The photo of which is presented below is a classic version of a road-type motorcycle of the middle class, designed to ride on tracks of completely different surfaces. The Izhevsk Machine-Building Plant was engaged in the production of this model. The popularity of the motorcycle speaks for itself, because almost everyone has it (and is).

Brief general information

The engine, which was installed on the IZH Planeta-4 motorcycle, had a fairly large thrust. In this case, the work was carried out at relatively low speeds. A side trailer (passenger or cargo type) or a universal module could be attached directly to the motorcycle itself. In addition, it was possible to attach additional knee pads and a trunk. In order to reduce the effort when disengaging the clutch, IZH Planet-4 uses a multi-plate clutch. In conjunction with the air cleaner, the oversized cylinder rib dampers help to reduce the noise level generated by the motorcycle. The front wheel of this model is equipped with a hydro-pneumatic type suspension with a disc brake.

Modernization

The production of the IZH Planet-4 motorcycle has undergone a number of changes. So, in the design, a generator was used, the operation of which is based on permanent magnets. This part also has a non-contact ignition system, which, in turn, works independently of battery... In addition, the engine itself is equipped with a special separating type lubrication pump. This made it possible to eliminate the need to use a gasoline-oil mixture. The IZH Planeta-4 motorcycle is equipped with a four-speed gearbox with an eccentric-type mechanism for disengaging the clutch and a more powerful motor chain. The front disc brake is hydraulically actuated and the suspension system uses improved shock absorbers. In addition, changes were made to the kinematics of the brake drive for the rear wheel.

Technical features of the motorcycle

Basic data: the distance between the wheel axles is set at 1 450 mm; at absolute load and tire pressure within normal limits ground clearance is 135 mm. Dimensions are as follows: length - 2200 mm, width - 810 mm, height - 1200 mm, weight (dry) - 158-165 kg, maximum carrying capacity - 170 kg, including load on the trunk equal to 20 kg. Motorcycle power is 22 horse power... At an optimal speed of 90 km / h, fuel is consumed at 5 liters per hundred kilometers.

Motor characteristic

The IZH Planeta-4 motorcycle is equipped with a 2-stroke engine, the cylinder size of which is 72 mm, and the volume is 3 346 cm. The lubrication system is separate, equipped with an oil pump that doses the feed depending on the frequency with which the crankshaft rotates and the load engine. There is an electronic type with regulation (automatic) of the advance in ignition, depending on the frequency with which the engine crankshaft rotates. However, it does not depend on the battery. For operation, it is desirable to use gasoline with an octane rating of at least 76. The engine uses an air cooling system. The transmission from the engine to the clutch is carried out using a double-row bush drive chain.

Checkpoint

Four-speed gearbox - three-shaft, it is located in one block with the engine. The gear ratio to the clutch from the engine is 2.17, while rear wheel from the gearbox - 2.33. In more detail about the rest of the gear ratios: 1st - 3.88; 2nd - 2.01; 3rd - 1.26; 4th - 1.0. The suspension of the front part of the motorcycle is telescopic, and the rear suspension is of lever type, with shock absorbers (spring-hydraulic). Rear brakes drum type, front - disc with hydraulic drive.

How is the IZH Planet-4 wiring arranged?

The motorcycle uses twelve volt equipment. Electrical wiring "IZH Planeta-4" single-wire type. The metal frame performs the "minus" task. It clearly demonstrates the main components of the IZH Planet-4 motorcycle wiring diagram of the ignition system, power sources, side lights and cornering lights, as well as head lights.

Generator

The motorcycle is equipped with a 3-phase alternator which has an electromagnetic excitation circuit. The principle of its operation is based on some features. So, the electrical circuit "IZH Planeta-4" looks like this: the current is supplied to the rectifier, which, in turn, converts it into a constant one, then through it supplies it to consumers. The following items are presented in the generator factory manual:

Voltage regulator with rectifier "BPV-14-10";

The head light circuit consists of a rear brake light, a parking light and a control color. The motorcycle is equipped with a speedometer with mileage indicators (daily and total), a tachometer, indicator lamps for direction indicators and headlights, a voltmeter and an engine temperature sensor. Very often during operation it is necessary to set the gap between the breaker contacts. To do this, it is best to use the scheme and special toolsto know which elements need to be dismantled.

IZH Planet 5 wiring diagram has a simple design: a single-wire network direct current provided by a 12 volt battery, which is charged by a 100–140 watt generator. The role of the negative wire in the electrical circuit is performed by the metal frame, and since the rest of the wiring has a positive charge, their short circuit is often the main cause of the malfunction.

Maintenance

The owner can independently perform some maintenance procedures:

• check the motorcycle generator if the battery loses its charge;
• set the gap between the breaker contacts;
• adjust the quality of the audio signal.

The need for inspection and adjustment of the wiring arises if:

• the motorcycle runs in the rain for a long time, as this causes oxidation of the contacts;
• the motorcyclist drives in an area with a lot of vegetation damaging the wiring;
• the driver rides in winter on snow, which can stick to the wiring parts and damage them.

Self-check of the generator of the motorcycle Planet 5 in case of loss of charge

The reason for the loss of charge in the IZH Planet 5 battery is most often a generator breakdown.

To check with your own hands you need:

• instrument multimeter;
• straight screwdriver.

Step-by-step instruction

The following steps must be followed:

1. Disconnect the wires from the battery and remove the generator cover.
2. Disconnect the top 5 wires from the generator by unscrewing their fasteners before that. In order not to confuse the wires during assembly, it is worth marking them.
3. Measure the resistance of the windings using a multimeter in ohmmeter mode. To do this, you need to touch one probe to the case, and the other should be connected in turn to the 3 winding wires. There should be no short circuits, as evidenced by the inscription on the multimeter screen.
4. Test the resistance between the stator contacts: it is necessary to touch them in turn with the probes of the multimeter. The display should be 8 ohms.

The presence of a short circuit at the 3rd stage or a mismatch of the indicators at the 4th stage will indicate problems with the generator.

Photo gallery: stages of checking the IZH Planet 5 generator with a loss of charge in pictures

Stage number 1. Photo disconnecting the generator from the battery Stage 2. Disconnecting the wires from the generator Stage number 3. Measuring the resistance of the windings Stage number 4. Testing resistance

How to set the gap between the breaker contacts correctly?

In order to set the gap between the breaker contacts, you will need:

• straight screwdriver;
• wrench 10;
• key for candles;
• stylus 0.4 mm thick (+/– 0.05 mm).

1. Place the motorcycle on a stand, transfer the box to neutral.
2. Remove the right crankcase cover and unscrew the spark plug.
3. With a 10 key, grab the alternator rotor mounting bolt and turn the crankshaft to the position where the contacts are as distant as possible.
4. Loosen the screw that secures the contact.
5. Place a dipstick between the contacts and adjust the eccentric screw to a position where the dipstick passes the contacts with little resistance.
6. Tighten the screw that secures the contact.

The IZH Jupiter 3 motorcycle was created as an improved model of the previously produced IZH Jupiter 2. For the first time in domestic practice, turn signals were installed on this model, which is why changes were made to the IZH Jupiter 3 wiring diagram.

In most cases, the wiring of IZH Jupiter 3 purchased from the hands is practically absent. The headlight does not work, the brake light, but in principle, except for the ignition, nothing works. Repair is required or rare cases replacement of wiring.

To get started, you need a wiring diagram for IZH Jupiter 3, such information is easy to find on the Internet.

Old Soviet wires are much better than modern counterparts, so you don't need to throw them away. After a visual inspection of the wiring and identification of obvious defects, the selected wires should be ringed with a tester for the presence of internal breaks.

It is necessary to carefully check the generator and the ignition system. With a long idle technique, the contacts of the breaker cams are oxidized. Cleaning is done simply, folded in half sandpaper "zero" is inserted between the contacts and rubbed until carbon deposits and rust are completely removed. To replace the high-voltage wire "armored wire" suitable automobile high voltage wires... An old spark plug with strong contamination is cleaned with a thin metal wire, all the dirt between the central electrode and the wall is cleaned out. Cleaning the plug contacts, like the ignition, is done with sandpaper. The gap is set with feelers in the range from 0.5 to 1 millimeter.

Incorrect operation of the ignition system can be caused by a breakdown of the capacitor insulation, which leads to a short circuit of the primary winding of the ignition coil to ground. A break in the capacitor lead wires leads to strong arcing at the contacts and a weak spark on the candle. Because of which the engine runs intermittently and starts with difficulty. If the capacitor is swollen and mechanically damaged, it will have to be replaced.
For proper maintenance and repair, the wiring diagram for IZH Jupiter 3 6 volts should be available on paper. Under the gas tank and the seat, there was a cable running to the rear turn signals and the brake light, it was necessary to additionally protect it, for example, wrap it with thin rubber from a bicycle camera. If necessary, the missing parts of the wiring can be purchased at the nearest auto parts store. Since it is very difficult to acquire "native" turn signals and brake lights, it makes sense to choose the ones that are suitable in design and quality.

The wiring must be solid, there is no need to twist the ends by hand and insulate with insulating tape. If, nevertheless, this cannot be avoided, the joints should be soldered and insulated with heat shrink tubing.

It is advisable to supply the terminals of the storage battery with lead with a bolt tightening. In old models of batteries, the caps of the cans were often unscrewed and the electrolyte spilled out. As a result, the wires and terminals were highly oxidized.

Ignition adjustment

First you need to determine which contact is used for which cylinder. Set the contact gaps to 0.4 mm, if the cam is badly worn, reduce the gap to 0.3 mm. Then unscrew the spark plugs and set the piston in one cylinder to the top dead center. Insert any clean stick instead of a candle and mark. Measure 3 millimeters from this mark, and set the piston to a new mark. Use a screwdriver to loosen the contact plate of this cylinder. Insert a tissue paper between the contacts and turn the plate against the stroke until the paper can be pulled out. Instead of paper, you can connect a light bulb, one wire to ground, the second to a contact. Turn the plate until the light comes on. The second cylinder is regulated in the same way as the first.

After all the procedures, it remains to fill in oil and gasoline, the motorcycle is ready for use. Good wiring is the key to long and flawless operation of Izh Jupiter 3.

Installation of BSZ on Izh Jupiter-5: system advantages

The installation of a contactless ignition system on the Izh Jupiter-5 is a rather relevant topic. When setting up BSZ on Izh Jupiter-5 BSZ, it is necessary to take into account a number of nuances that can significantly affect the operation of the equipment used.

What are the advantages open to users who decide to install electronic ignition on Izh Jupiter, are described below.

Most modern motorcycles are not equipped with cams, that is, breakers. Why did the manufacturer consider them unnecessary for the models currently on sale? The answer is simple enough. This system is not very reliable.

A lot of the parts used in the system are sources of trouble. The most common ones are listed below:

1. Ignition gaps change their original position during driving a few days after adjustment;
2. A spark occurs every other time, since the contacts burn regularly;
3. Beating of capacitors constantly occurs;
4. Low spark power;
5. When the battery is lowered by two or three volts, it is quite difficult to start it. This ignition is the reason for constant repairs while driving.

Many people mistakenly believe that it is very difficult to implement BSZ sovek on Izh Jupiter 5. As a rule, the purchase of the necessary spare parts takes more time than the installation of a BSZ on an IL. Of course, after implantation, the working capacity changes significantly in best direction.

This is noticeable on idle... The speed of their passage has noticeably increased and unnatural twitching has disappeared. Also, the characteristic knocking of iron components in the crankcase and accompanying detonations disappeared. The handling of the Jupiter 5 motorcycle will improve at the same time as it accelerates.

Required details

In order for the ignition system to function properly, a number of auxiliary parts are required. They are listed below:

• Switch for BSZ of a VAZ car. You should not choose exclusively from the low price segment. The Astro switch has a lot of positive reviews;
• Hall Sensor. The best option for Jupiter 5 - a similar manufacturer VAZ. By purchasing it in branded packaging, you protect yourself from counterfeiting;
• Ignition coil with two leads. You should choose between gazelle engine number 406 or Oka with electronic system ignition;
• A pair of silicone armor wires with rubber caps;
• A modulator is a butterfly-shaped plate made of iron.

Modulator

The most difficult stage is the production of the modulator. It is important to keep the required shape The more reliably the required dimensions are observed, the lower the likelihood of malfunctions after the implementation of the system, that is, there will be no need to adjust it with a file. The ignition timing must match on any cylinder used.

The bolt hole must be centered. Otherwise, the motor will not be synchronized. It is also recommended to check the integrity of the crankshaft bearings. If you find defects, you should immediately replace them.

Contact ignition is not able to work normally with dead bearings. The thickness of the part should not exceed one and a half millimeters. If it is thin, it will not be possible to avoid deformation, and the thick one is in contact with the surface of the hall sensor housing.

Any material other than steel can be used to create the plate. Aluminum and others should not be used, as they are not magnetic. The drawing to be followed can be found in the public domain. The presented diagram will be useful to those persons who have decided to upgrade the ignition device. vehicle... Below are the installation techniques electrical devices ignition into Jupiter.

It must be turned by a professional turner. He will make a simple disk and draw on it the markings of the elementary distances between the corners. After that, in accordance with it, you will cut out the necessary sectors at home. The cost of the modulator is seventy rubles.

It is impractical to use an ordinary plate, since its width is less than twelve millimeters. This will not be enough for the full accumulation of the energy resource in the coil. Of course, it can be installed, but reaching four thousand revolutions per minute will become impossible.

In addition to the above, you will need:

• A threaded stud seven millimeters step 1, as well as a pair of nuts with washers of the corresponding parameters. The priority material for these components is brass. This is due to the least magnetization of the plate from the generator rotor.

  If you use a standard bolt, then there may be difficulties with the introduction of ignition. The bolt tends to rotate the modulator next when tightening. However, it is necessary to observe the leading indicator, maintain a single position of the rotor and modulator, tighten the bolt. It is advisable to use a hairpin, since many are not able to perform all the necessary actions in combination;

• A set of wires with connectors for ignition without contact from VAZ. This part can be purchased or made with your own hands.

System collection and installation

The contacts in the breaker, capacitor, ignition bobbins and armor wires, which are part of the previous ignition device, are probably eliminated. The switch should embed the glove compartment on the right and the ignition coil directly under the tank. There are no mounting gaps on the spool, which means it can be attached with a massive layer of adhesive tape. The stock bolt is also canceled with other parts.

In place of the bolt, install a stud of the specified size and put on a washer. Then, the rotor is tightened with a nut at its end. The hall sensor is attached to the stator by any means. The basic rule when installing it is to set the optimal distance of the modulator section and the ratio of the radius and the line of symmetry.

When the hall sensor can be fixed, we apply the modulator. It must fit into the drilled hole in the sensor. In most situations, there is a discrepancy in size, so it is necessary to place the washers on the stud. If it was possible to maintain the required clearance, then it is recommended to install the engraver and tighten the modulator with a third-party nut.

Final steps

It is necessary to put on rubber caps on the armor wires, and insert the latter into over the candlesticks or coil. If you skip this step, the motorcycle will stall when riding in rainy weather, as moisture gets into the battery.

By inserting the candles into the tip, it will be possible to maintain excellent contact between the battery and the vehicle volume. Now you will need a pre-purchased set of wires. The switch, coil and hall sensor are wired. It needs to be isolated. Of the entire mass, an exclusively general plus is required.

Setting suitable parameters

Tuning the BSZ to Izh Jupiter 5 also requires special attention. The ignition is switched on with the tachometer connected. After thirty seconds, indicators of 3000, 4000, 5000 rpm should appear on the device panel. If present, the switch is operating correctly.

In other cases, you should pay attention to the previously grounded candles. We insert the screwdriver into the hall connector, and then take it out. A spark should appear on the candles. If it was not possible to cause a spark with the above actions, then the reason for the incorrect operation is the incorrect connections.

The setup looks like this. The hour-shaped indicator is unscrewed and the cylinder piston is fitted. Having connected a voltmeter to the second and third connectors, it is necessary to start rotating the modulator axis. After a jump from 7 to 0.1 volts is detected, the modulator must be secured with a nut. Usually set the required lead angle.

The test run should be successful if the components are self-installed according to the instructions. Now you can use the BSZ.

IZH Jupiter 5 and its electrical equipment: briefly about the main

Unlike similar motorcycle models of the Soviet era, the diagram electrical wiring motorcycle IZH Jupiter 5 provides for operation from a battery with air cooled equipment. This causes many problems for owners. The article provides recommendations for modernization that solves the problem with sparking.

IZH motorcycle models are maximally unified. The wiring diagram for IZH Jupiter 2 is not much different from the later versions of the IZH motorcycle. There are external differences. For example, the Planet 5 bike has one cylinder, while Jupiter 5 has two.

The first 12-volt motorcycle was IZH Jupiter 4. The wiring diagram of IZH Jupiter 5 and the wiring diagram of IZH Jupiter 3 differ in components.

IZH Jupiter 5 wiring diagram

On the bike of the fifth Jupiter there is a contact SZ, which runs on a battery, so the operation of the transport depends greatly on the degree of battery charge.

If the charge is insufficient, the following problems arise:

• the motor runs intermittently;
• the engine is difficult to start;
• at low speed the battery is discharged.

You can eliminate these problems by going to BSZ. Any electrician can handle this task (video by Viter Electronic).

How to make the transition to contactless SZ?

To switch to contactless SZ, motorists use parts from other motorcycle models. When upgrading the generator set, the wiring of the IZH Jupiter 5 remains unchanged. Small alterations concern the IZH electrical circuit. After the changes, the battery is used for servicing auxiliary equipment. To go to BSZ, parts are taken from Planet 5 and a VAZ 2108 car.

The following changes are made to the IZH electrical equipment diagram:

• install 2 Hall sensors from the eighth VAZ model;
• to the sensors you need to connect 2 VAZ electronic switch;
• each of the cylinders serves a switch-sensor pair;
• two more ignition coils must be added to the circuit.

SZ after modernization

On the IZH motorcycle wiring diagram, the components are marked with numbers:

1. Spark plug.
2. Ignition coils from Planet 5.
3. Switches.
4. Hall sensors.
5. Egnition lock.
6. Battery.

For the created ignition system, it is necessary to modify the IZH Jupiter 5 generator, the circuit of which does not require major changes.

How can the generator be modified?

The presented modernization option is advantageous in that it does not require the purchase of a new generator that will serve new system ignition.

Recycled generator device

It is enough to follow these steps:

• to make a modulator-electric circuit breaker;
• install a breaker on the rotor shaft or generator.

You can create a modulator with your own hands. To do this, take a metal plate and drill a hole in it for the fastening bolt. The manufactured part will serve as a modulator-chopper.

Homemade modulator for interruption

The modulator is connected as follows:

• install the modulator plate (2) and tighten it with the bolt (3), but not completely;
• rotating the crankshaft, you need to ensure that the piston is in top dead point;
• then you need to set the ignition timing;
• the mounting bolt on the plate can now be tightened.

Hall sensors (1) are installed together with the modulator.

Improving the standard system

The ignition system can be improved in other ways. To do this, you need to identify what problems with the wiring are. They can occur in the primary circuit between the coil and the 12 V battery or are caused by operating conditions. A visual inspection of the primary circuit can reveal malfunctions in the connections, contacts and the ignition switch.

If operating conditions are ideal, the primary circuit operates with a 12V battery without interruption.

But when dirt and dust gets into the circuit, the resistance at the contact points increases, which entails a decrease in voltage from 12 Volts to 7-8 Volts. This voltage is not enough for a powerful discharge to appear in the secondary winding of the coil. As a result, a charge of less than 12 V appears on the spark plug, which badly ignites the combustible mixture in the cylinders. Burnt contacts, oily candles and batteries with a charge less than 12 V further worsen sparking.

Regular wiring after revision

The following measures can help solve these problems:

1. The plug connectors are removed and each wire is soldered using traditional soldering and then insulated.
2. An additional toggle switch is installed that turns off all consumers when the engine starts. Thus, the coils are supplied with 12 volt voltage from the battery (diagram 1).
3. Redesign the ignition lock (ЗЗ) (diagram 2). You need to take the wire and solder one end of it to the lock connector 4, which is free, and the other to the positive terminal of the coil. The standard wire should be re-soldered from terminal 5 to terminal 6. After turning on this key position, the power supply from the battery to the primary circuit is carried out according to a simplified scheme.

Thus, the changes made will make the wiring of the IZH Jupiter 5 motorcycle more reliable and efficient.

Contactless electronic ignition on the legend of the domestic motorcycle industry - IZH Jupiter 5

Motorcycles IZH are rightfully considered the legends of the national automotive industry... The use of these vehicles was especially important in soviet years, however, even today IZH is successfully used by many domestic motorists. In this article we will talk about what electronic ignition is on the IZH Jupiter 5 motorcycle and how the ignition system (SZ) is set up.

Tuned motorcycle IZH Jupiter 5

IZH Jupiter 3 uses contactless ignition (BSZ) 1137.3734, intended for all models equipped with a 12-volt generator. The ignition coil module for Jupiter 4 or another model makes it possible to select the appropriate operating mode of the engine due to the serial connection of the output wires.

The device as a whole improves technical specifications vehicle thanks to:

• improved engine start at low temperatures;
• more stable work power unit, which is achieved as a result of reducing the asynchronous formation of a spark, as well as by optimizing the lead angle of the SZ in accordance with the motor speed;
• reducing the level of toxicity of exhaust gases, fuel consumption, as well as reducing plaque on candles;
• stable start of the power unit even on a battery that has run down to 6 volts, provided that certain models ignition coils;
• easier installation and maintenance of the system as a whole.

Technical data

Contactless SZ operation on Jupiter

Let us briefly consider the main technical parameters characteristic of the third IL model:

1. The negative terminal of the battery is always grounded, the battery voltage level is 12 volts.
2. If the ignition switch is off, respectively, the engine does not work, the current consumption parameter will be no more than 0.15 amperes.
3. The unit allows you to ensure the uninterrupted appearance of a spark if the number of crankshaft revolutions does not exceed 7 thousand per minute. The level of current that the node consumes in this case will not exceed 2.5 amperes.
4. In addition, the mechanism also allows for the uninterrupted formation of a spark if the voltage parameter in the electrical circuit changes from 6 to 16 volts. At this time, the voltage indicator on the candles will not change.
5. According to technical data, the unit can function normally if the air temperature is between 25 degrees below zero and 60 degrees Celsius.
6. Thanks to the use of a microprocessor component in the operation of the unit, the formation of the torque allows for the correct and stable operation of all other mechanisms. Of course, if at the same time the power unit is working in normal mode.

Scheme

IZH motorcycle ignition circuit

As for the circuit, the optical ignition on the IZH Jupiter 5 or any other SZ is mounted using spare parts and fasteners that are included in the kit. As you know, the mechanism is designed to ignite the air-fuel mixture. The mixture itself, which is located in the engine cylinder, ignites due to the spark formed between the spark plug electrodes. It's not a secret for anyone that the quality of the SZ functioning largely affects the operation of the entire vehicle.

As practice shows, one of the problems of IZH is that the lead angle periodically gets lost. This is due to wear on the cams as well as on the interrupter contacts. It should be noted that mechanical effects in the electronic SZ are completely absent.

The pulse is removed in a separate block, while the signal goes to the switch, where it is amplified. Subsequently, the impulse goes to the coil, then everything happens as usual. A discharge is supplied to the spark plug, which contributes to the ignition of the mixture, as a result of which the crankshaft begins to move. It is not so difficult to replace the device or adjust it at home, but you must remember that improper actions can lead to possible malfunctions further.

To tune the system on a motorcycle, it is advisable to use devices with a scale of up to 15 volts and an internal resistance of up to 0 kOhm. Thanks to the electronic device, adjusting the assembly does not take much time and effort. The terminals from the device must be connected to the Hall sensor. More detailed setup procedure contact ignition without the use of auxiliary devices is shown in the video below (the author of the video is the Khan Rulu channel).

So, for the correct adjustment, place the cylinder piston in the position for the most optimal sparking. Any cylinder can be used. Then the ignition is activated, while the modulator device must be turned in the direction of the rotor movement by the crankshaft. Rotation is carried out until the changes are visible on the voltmeter screen. The moment you can catch a spark, the position of the shutters should not be changed. As for the modulator device, it must be securely fixed on the generator shaft, for this, a fastening screw is used.

During adjustment, in any case, short-circuit the high-voltage on the motor housing. This is done so that when using the short circuit, the system does not overload, which ultimately can lead to the failure of the BSZ. In addition, the operation of the motor cannot be stopped when removing the spark plug caps.

After the adjustment has been made, the performance of the system must be checked. If you place the cable under test about 7-8 mm from the power unit, and then try to start the engine, a spark should slip through. As you can see, in general, the procedure for setting up a node is not particularly complicated, but it requires care and the correct approach, so the above recommendations are still worth considering. In addition, do not forget about safety precautions, since improper actions can lead to a short circuit in the wiring and failure of the unit as a whole.

Improving the car, the plant made a number of changes to it. In particular, the fixation and accuracy of operation of the IZH P101 and IZH P102 switches and the steering wheel switch have been improved. The optical element of the company "Hella" in the headlamp was replaced by the Soviet FG 137, and the lamps IZH UP1 of the direction indicators were replaced by unified lanterns 16.3726. There are other innovations as well.

Now Jupiter-4 is also equipped with 12-volt equipment. The plant prepares for production and new model "Planets-sport", the electrical equipment of which is unified with "Jupiter-4".

However, even now the owners of Planeta-Sport can use a number of IZH Yu-4 electrical appliances without significant alterations. These include the 28.3701 generator (if it is sold without a breaker and a capacitor, they can be taken from the old IZH GP1); direction indicator lamps 16.3726; FG 137 headlamp optical element; rear light FP146; speedometer SP102; rechargeable battery 6MTS-9.

To install an IZH RP2SM-10 turn indicator interrupter in the headlight housing, an additional bracket must be made of a steel strip 1-1.5 mm thick and the plug-in tips must be replaced with round ones. After the same alteration of the handpieces, the combined switches IZH P101-20 and IZH P102-20 from the motorcycle IZH Yu-4 can be used on Planet-Sport. To do this, pressing the fixing antennae with an awl or knitting needle, remove the plug tips. Cut them off and crimp and solder round tips at the stripped ends of the wires. At the IZH P101-20 switch, a blue lead wire 130-150 mm long with a plug tip is also soldered to the black wire.

The improvement of the electrical equipment of motorcycles and the use of new devices led, naturally, to some complication of the electrical circuit. Let's get acquainted with its main elements using the example of the electrical equipment of the Planet-Sport circuit, which is in many ways similar to the circuits of other Izhevsk motorcycles.

Ignition system... This is perhaps the main system, because without it the motor cannot work. Let's trace and remember its electrical circuit. From the storage battery 24, through the fuse 25 and the rectifier 26, power is supplied to terminal (2) of the connecting panel in the headlamp housing and then to terminal (3) of the ignition lock 9. When its key is turned to position I, the terminals (3-2 - 1 and 5 —6). Now, from the terminal (1) of the lock, the current goes to terminal (5) of the connecting panel, from it to the emergency ignition switch 11, and through its closed contacts to terminal (1) of the connecting panel and then to the primary winding of the ignition coil 21 (the second end of the primary winding - terminal "-" is connected to the breaker). This engages the motorcycle ignition circuit.

If the engine does not run because there is no spark on the plug, check for high voltage. To do this, remove the wire from the cap and bring it to the edge of the cylinder with a gap of 2-3 mm. If when rotating crankshaft With the kick starter, a spark between the wire and the cylinder will not appear - there is no high voltage. The reason for this is found as follows. When the ignition is switched on with a 12-volt control lamp, it is checked whether power is supplied to the "+" terminal of the ignition coil. If not, then check the entire circuit, starting from the battery. Loose or oxidized terminals and a defective fuse are common causes of no voltage.

Having achieved that on the terminal "+" of the ignition coil appears normal voltage, carefully clean the breaker contacts, check and set a gap between them of 0.4—0.6 mm and adjust the initial ignition timing.

If the engine gives only individual flashes when starting, and a white coating appears on the contacts of the breaker, it means that the capacitor has failed (rarely, but this happens).

With the correct clearance, clean contacts of the breaker and a working capacitor, the reason for the absence of a spark on the candle may be a malfunction of its plastic cap (breakdown to ground) or the ignition coil (it is non-separable, therefore it is replaced). A poor quality spark plug can cause the engine to malfunction or make it difficult to start. Alarm and lighting system

Direction indicator... When the ignition is turned on (the key is in position I), electricity from the storage battery 24 (or rectifier 26 with the engine running) is supplied through terminals (3 and 1) of the ignition switch 9 to terminal (5) of the connecting panel. The power wire of the relay 6 of the direction indicators, the sound signal 18 and the "plus" wire of the light switch 11 located on the steering wheel are connected to it. From relay 6, power is supplied to the lights through the terminal (9) of the connecting panel and then to the turn signal switch 19. From it, through the terminals (6 and 7) of the connecting panel, it goes to the lamps 10 and 28 of the direction indicators. The indicator lamp 16 of the direction indicators is also connected to the terminals (6 and 7) of the connecting panel through the block of diodes 7.

The reason for the refusal in the operation of direction indicators is most often the lack of "mass" in the lanterns when they loose their attachment to the frame, oxidation or weakening of the connections of the tips with wires, contacts in lamp holders.

To speed up troubleshooting, the circuit is checked from the idle consumer to the power source. To find out the operation of the direction indicator relay 6 without dismantling it, you must first make sure that voltage is supplied to the terminal (5) of the connecting panel, and the brown wire of the relay is reliably connected to ground. Then check the serviceability of the circuits going to the direction indicator lamps by shorting the terminal (5) with the terminals (6 and 7) of the connecting panel with a separate wire. The lanterns of the right (terminal 6) or left side (terminal 7) and the control lamp 16 should be on without blinking if the circuits are in good condition. Then disconnect the pink wire of the relay from terminal (9) and connect it to terminals (6 and 7) of the junction panel. With a working relay, the lights of the starboard or port side should flash at a frequency of 60 to 120 per minute.

The relay removed from the motorcycle is checked using two A12-21-3 control lamps (power of each 25 W), connected in parallel. Connect the "plus" of a constant voltage of 12 volts to the red wire, "minus" to the brown wire, and control lamps to the pink wire. With a working device, the lamps should flash at a frequency of 90 ± 30 per minute.

Headlight... It contains the main part wiring diagram, turn signal relay, control lamps of neutral 3 and oil pressure 5, lamp 8, illuminating the speedometer scale, lamp 1 of the parking light, lamp 2 of the head light, ignition switch 9 and the speedometer.

On the latest motorcycle models, the direction indicator interrupter is mounted on the frame under the gas tank.

Consider the electrical circuit of the head, parking and side lights. When the ignition is on (the key is in position I), power is supplied to the terminal (4) of the connecting panel, then through the contacts of the light switch 11 - to the central contact of the high-low beam switch 19. Further, through the terminals (11 and 12) of the connecting panel - to the thread of the high or low beam of the lamp 2.

Side light in the headlamp (lamp 1) and in rear light 29 lights up when the switch 11 is triggered and current flows through contacts (5 and 6) of the ignition lock 9.

If the key in the ignition switch is turned to position II (parking), then these lamps are powered through its contacts (3 and 5), regardless of the position of the switches on the steering wheel.

Weak lights when the engine is not running indicate that the battery is not fully charged. If this is observed in all operating modes of the engine, it means that the voltage in the lamp supply circuit drops dramatically. In this case, check the electrical connections of the power and ground wires, clean and tighten the screw and plug connectors, contacts in the headlight and lamp holders. Check the integrity and reliability of the contacts in the switches and fuse.

Since the motorcycle is constantly being improved during the production process and its electrical circuit changes, it is advisable to include the differences between your motorcycle in the diagram printed here, so that, using it, you can always easily and quickly find the desired chain and determine the malfunction.
