Wiring diagram UAZ 459. Electrical equipment repair service UAZ vehicles

It is difficult to imagine how a car would be organized without electrical filling; for this reason, the UAZ 31519 wiring diagram occupies an honorable place in the description of the car. As an integral part of the modern car, this connection of units and functional elements is constantly being developed and improved. Without a well-drawn up drawing, it is impossible to understand the kilometers of conductors and understand the connection with the rest of the equipment. Changes to the design, connection of an additional consumer, correction of damaged elements will certainly force you to refer to the UAZ 31519 electrical circuit. For ease of reading, the circuit is made in color.

general information

A car with all-wheel drive UAZ 31519 was produced at the Ulyanovsk plant in the period from 97 to 2013. The main goal of designing the unit is to replace the obsolete UAZ 31514 with a model with higher power. On the basis of the car, modifications have been created that differ among themselves in the level of interior trim and power plants. Due to the use of users with different characteristics and parameters, the UAZ 31519 electrical equipment diagram also contains individual features.

The connection of users of the UAZ 315195 car, etc. is carried out according to the principle of a single conductor, when the positive terminal of the equipment is connected in one circuit. The negative leads are attached to the machine frame, which plays the role of the second conductor. The car's mains voltage is 12V, the protection of the equipment was taken over by the block of safety elements.

The connection between energy consumers takes place by means of a composite exciter key, in which the contacting part and the anti-theft equipment are structurally provided. The wiring diagram of the UAZ 31519 provides for the power supply of consumers using a current source until the power plant is activated. After activating the motor, power is provided by a generator that generates an alternating current and passes the energy through the rectifier unit. In addition, the product charges the rechargeable battery to keep it operational. You can also read about.

Circuit breakers

In order to preserve the integrity and operability of the circuits, the UAZ 31519 circuit provides for the use of disconnectors. The product is made using the technology of joining two metals, and is placed below the dashboard. Three main protective elements, with a value of 10A, are installed in a special compartment PR103, located between the engine and the passenger compartment.

Purpose of disconnectors:

  • Fuse 1: protects control devices;
  • Fuse 2: protects turn signaling devices;
  • Fuse 3: protects the alarm and horn.

Disconnector # 1 is located on the starboard side of the machine. The power supply of the stove fan is protected by a 6A disconnector. The product is mounted near the stove switch. UAZ cars: 315192, 315194, etc. sometimes contain additional disconnectors, since the kit is changed.

Circuit supervision

The control of the circuits of UAZ-315194 machines, etc. without switching off the voltage, is carried out by a voltmeter or ammeter. The first is connected in parallel, connecting to the tested segment or device. Measurement range "0-25" V. During manipulation, the negative wire is attached to the car frame, the positive wire is attached to the user or supplier. A decline in the effective electric field indicates a malfunction of the chain system (short circuit, rush, oxidation, etc.). The control is carried out by a light bulb, the power of the product does not exceed three, four W; voltage twelve V.


Verification with an ammeter is carried out with a maximum limit of at least 10A stable current. The incorporation of the device is consistent with respect to the controlled item. Positive contact relates to the source, negative - to the consumer. At a current value below the required level, they speak of a malfunction of the electrical circuit, above it indicates a consumer short circuit.

From the beginning of production until the mid-80s, a simplified wiring diagram for the UAZ 469 and 469B was used. The cars were supplied mainly to the army, therefore they were equipped with contact ignition and did not have electronic devices. After the modernization, the designation of the car was changed to UAZ 3151, and the electrical circuitry of these SUVs changed accordingly.

Generator G250 350 W

The generators with improved parameters installed on the later UAZ 3151 cars are connected in a similar way.

Ignition

On all-terrain vehicles UAZ, there are two types of ignition systems - contact and transistor. The first model was used on the UAZ 469 / 469B, but from the mid-80s it was supplanted by the contactless one. Gradually, the owners changed devices on early cars, so it's rare to find a car with a "classic" system.

Contact ignition circuit

Contact ignition elements for UAZ 469:

  1. Battery.
  2. Starter Solenoid Relay.
  3. Coil.
  4. Fuse box.
  5. Current meter.
  6. Mass switch.
  7. Voltage regulator module.
  8. Generator.
  9. Egnition lock.
  10. Moving contact (slider).
  11. Additional capacitor.
  12. Spark pulse distributor.
  13. Candles.
  14. Additional resistors in the tips.

Classic ignition circuit with mechanical contact group

Electronic ignition circuit

The UAZ 3151 began to use a non-contact system with improved characteristics.

Ignition system components:

  1. Coil.
  2. Transistor switch.
  3. Pulse distribution sensor.
  4. Candle.
  5. Fuse box.
  6. Vibrator of the emergency ignition system.
  7. Additional resistor.

Transistor ignition system

To connect the parts of the contactless fuel ignition system, wires with different colors of insulation are normally used:

  • blue (G);
  • red (K);
  • yellow (F);
  • green (H).

The difference between ignition systems

The difference between the contact ignition system is a contact group that distributes high voltage pulses. Because of this, the assembly is prone to overheating and burning, which impairs the transmission of current. In a contactless system, signals are generated by a Hall sensor and a transistor switch. The design has no mechanical elements subject to active wear and is capable of operating at reduced voltage in the on-board network.

Common faults

Breakdowns associated with the UAZ 469 wiring diagram:

  • battery discharge;
  • broken wires due to mechanical stress or corrosion;
  • voltage drop in sections of circuits due to oxidation of contact connections;
  • lack of charging due to wear of the brushes on the generator or insufficient tension of the belt drive;
  • the output of a part of the electrical circuit due to a blown fuse;
  • burnout of one or more lighting lamps;
  • problems with the starter retractor relay.

Preventive measures

The main measures for the prevention of electrical system malfunctions:

  1. Regularly check the condition of the cable lugs installed on the battery terminals. Clean parts from oxides and dirt.
  2. Wipe off dust from the battery case. If a serviced battery is used, then it is necessary to clean the ventilation ducts and bring the electrolyte density to normal. Recharge the device periodically using the charger.
  3. In case of long downtime, disconnect the battery using the standard disconnect switch.
  4. The wiring harness must not bend or chafe against the sharp edges of the body panels. If insulation damage is found, restore the protection with insulating tape or replace the wiring section. Protect kinks with special sleeves.
  5. If the fuse blows, determine the cause of the breakdown. It is forbidden to make repairs by installing reinforced elements designed for increased current.
  6. Monitor the condition of the starter by periodically cleaning the rubbing elements from dirt and lubricating them with Litol-24. Check the axial clearance of the rotor, which should be within 1 mm, and the tightening of the bolts securing the unit to the crankcase. Electrical contacts must be cleaned of carbon deposits with a file.
  7. Clean the distributor slider from dust and grease with a rag and clean gasoline. Simultaneously lubricate the rotor bushing (a few drops are fed under the removed felt). High-voltage wires must be tightly installed in the seats. If moisture gets on the elements, wipe them with a clean and dry cloth.
  8. Do not abuse the use of an emergency vibrator, which has a service life of about 30 hours. Deactivate the carburetor economizer when the backup ignition is switched on.
  9. Check the fastening of devices in the instrument cluster, replacing burnt-out parts.

DIY repair of wiring and electrical equipment

The main malfunctions of electrical equipment on the UAZ 469 and repair methods:

  1. If there is no battery charge, check the tension of the alternator drive belt and the condition of the brushes. The problem may arise due to wear of the slip rings or the rotor rubbing against the stator (bearing wear). The exact cause of the breakdown can only be determined after removing the generator and troubleshooting the components.
  2. An overcharged battery indicates a breakdown of the voltage regulator, which must be replaced.
  3. Generator running noise is a sign of bearing wear or bearing wear. Worn and damaged parts require replacement.
  4. The absence of sparking in a contactless ignition system indicates breakdowns of the coil or cover, as well as incorrect adjustment of the lead angle. Possible breakdown of the switching device. For repairs, it is required to replace broken units and adjust the moment of spark supply.
  5. Burnt-out products must be replaced with parts with similar parameters. Periodically adjust the headlight beams (as well as fog lamps, if installed).
  6. A rattling sound during horn operation is caused by poor contact or cracks in the membrane. Repair requires checking the condition of the wiring and connection points. The damaged audio signal is replaced by a new one.
  7. If a short circuit is detected in the circuit, it is necessary to find out the cause of the malfunction. To do this, you need to go through all the elements connected to this wire. Each consumer is disconnected from the network and separately checked for operability. If the insulation on the wiring harnesses burns, they must be replaced.
  8. When replacing a wiring section, it is required to ensure a reliable connection of the old and new sections. The fastest technique is to twist the bare areas, but this method does not provide reliable contact and long service life. A more reliable joint can be created by installing a special crimping sleeve. After installing the element, it is necessary to protect the bare area with insulating tape. The third method of connection is soldering the wiring, which provides a strong joint, which in its characteristics is somewhat inferior to crimping.

How to install the ignition yourself

Contact ignition installation instructions:

  1. Unscrew the spark plug from the first cylinder (from the pulley).
  2. Determine the moment the compression starts. For this, the hole of the candle well is clamped with a finger, and the assistant turns the shaft with a handle. The moment the air starts to escape is the starting point of the compression cycle.
  3. Turn the crankshaft until the hole on the pulley coincides with the special pin installed on the timing gear cover of the guitar.
  4. Check the position of the rotor, the contact of which should be located opposite the inner conductive element of the cover, which supplies a voltage pulse to the first cylinder.
  5. Loosen the screw and turn the octane-corrector plate until the pointer coincides with the middle part of the scale.
  6. Then grab the distributor body and gently turn it counterclockwise until the contact group closes.
  7. Disconnect the wiring from the engine compartment lamp.
  8. Use a separate harness to connect the lamp terminal to the ignition coil connector. A wire is attached to the same element that goes to the ignition distributor.
  9. Turn the key in the ignition lock. Then smoothly rotate the distributor body until the lamp turns on. At this stage, it is important to fix the very initial moment of the flash, the accuracy of the adjustment depends on it.
  10. Hold the distributor housing in the found position. Then tighten the fixing screw and replace the cover.
  11. Check the correct installation of high-voltage wires.

How to adjust the ignition

The first stage in adjusting contact ignition is setting the gaps:

  1. Remove the spring clips and remove the cover from the distributor.
  2. Remove the slider rotor.
  3. Turning the crankshaft using the starting crank or wrench, set the cam position that provides the maximum clearance in the contact group.
  4. Measure the gap value with a feeler gauge. A value in the range of 0.35-0.45 mm is considered normal.
  5. If the gap is increased or decreased, loosen the fixing screw of the fixed contact. Then turn the adjusting eccentric unit (has a separate flat for a screwdriver).
  6. After setting the gap, tighten the locking screw and re-measure.
  7. Reinstall the removed parts. If further adjustment is required, only the runner rotor needs to be mounted.

To control the ignition parameters, warm up the engine to operating temperature and check the acceleration of the car at a speed of 30-35 km / h. The vehicle must be in direct gear. With correct adjustment, a short-term detonation with a low intensity will occur. If it is noticeable, then you should turn the octane corrector one division counterclockwise (change the ignition timing).

The sequence of steps and features of the non-contact ignition adjustment:

  1. Set the piston in the first cylinder to the position of the end of the compression stroke. This requires aligning the marks on the pulley and gear cover.
  2. Remove the cover from the distributor.
  3. Check the contact position of the slider. The conductive plate must be located exactly opposite the element marked "1" on the cover.
  4. Unscrew the fastening bolt and turn the octane corrector plate to the middle position (on the scale and indicator), and then tighten the fastener.
  5. Unscrew the fastening of the corrector plate to the distributor housing.
  6. While holding the slider with one hand, turn the body clockwise. The purpose of the operation is to match the red mark on the rotor surface with the pointer tip. Then fix the knot in the new position.
  7. Reinstall the removed parts and check the correct installation of the wires and the integrity of the insulation.

The check is carried out according to a similar method, only the acceleration starts from 40 km / h and is carried out up to 60 km / h. After that, the detonation should disappear. If necessary, turn the distributor by 0.5-1 division of the octane-corrector scale (counterclockwise). If there is no detonation at all during acceleration, then the assembly rotates clockwise.

In modern UAZ models - Patriot and Hunter, there are very often cases of fire in electrical wiring! Be vigilant, regularly check the electrical equipment of the car, install only standard fuses (ours are not Chinese!). Make sure no water gets into the computer.

The tachometer (from the six) looks perfect next to (to the right) of the speedometer. The connection is standard - everything is written there on the tach case. One - per coil (either low-voltage end). One - + 12V. One is mass. One is taha lighting. For fun, you can connect the parking brake light. The generator failure lamps will remain, but this cannot be connected without a relay. And the lamp of the open (closed) air damper of the carb. The last three are not connected to me, I don't want to mess around yet. I drilled the hole with a 2.5 mm drill in a circle less than the diameter of the tach circle by 3 mm, then finished it with a round file. The holes need to be screwed first. Do not press hard with a drill! Otherwise, the panel will be wrapped on the last holes.

(from UAZ-Hunter to a regular UAZ)
Electronic speedometer AR 20.3802 (two-line display:
the upper line - the total mileage (6 digits, insignificant zeros are highlighted), the lower line - the resettable daily distance counter), the AP 68.3843 speed sensor (six-pulse, no-pass, M22 thread, Kozmodemyanovsky connector).

There was only one difficulty during installation - a complete lack of information about both the speedometer and the Hunter's electrical circuit. Searches did not give any results. It was also not possible to find a native harness with connectors. I had to use the scientific poke method. Everything is clear with the sensor: red - power supply (+12 V) (after ignition), blue - signal, black - ground. (The connector was simply cut off). The speedometer connector looks like this (the numbering of the contacts is conditional):

The purpose of the conclusions was established:
1. Earth.
2. Power supply (+12 V). (After ignition switch). (When voltage is applied, the liquid crystal digital display turns on. When the voltage is removed, the distance traveled readings are saved).
3. Signal from the sensor. (To blue sensor wire).
4. Night illumination (for lighting devices).
5. Output 12 volts to power the speed sensor.
6. High beam indicator (the symbol in the center of the scale lights up).
7. Nothing happens. (Probably not involved).
Due to the lack of a mating connector, I connected it with single wires with soldered lugs ("mothers") from the audio equipment. Everything works. Doesn't make noise. The arrow does not jump. The error is minimal. And at night - generally beautiful.

Note: when laying wires with a cross-section of 0.5 - 4.0 mm2 in bundles, the cross-section of which along the route contains from two to seven wires, the allowable current in the wire is 0.55 of the current in a single wire according to the table, and when the presence of 8-19 wires - 0.38 of the current in a single wire.

Causes:
First: Belt tension.
Second: The diode bridge (horseshoe) partially burned out. This is a replacement
Third: What I had. The bastardly thin wiring from the generator should pass all 65a. charging current, and mine was charred and half burnt near the attachment to the generator. This was the reason. It is imperative to change it entirely.


Luggage compartment lighting

I made the trunk light according to this scheme. The location of the tip and switch can be seen in photo 1, the lanterns in photo 2. If the secret police is not worth it, then decoupling diodes are not needed. It is possible without a tip, then you can only turn it on manually (now there are three positions: off, on manually, on automatically when you open the trunk).

Wiring diagram UAZ-469 combines all devices and devices used in a car. In the event of malfunctions in the operation of the system, the full operation of the car can cause difficulties for the car owner, so all breakdowns must be promptly eliminated. You can learn more about malfunctions, as well as wiring prevention, from this material.

What is included in the wiring diagram?

Above is the form of the wiring diagram.

Regardless of which UAZ you are using - old or new - the main components of the electrical network are as follows:

  1. Dashboard. The main sensors and indicators are displayed on it, indicating the inclusion of a particular device. The tidy allows the driver to know at what speed he is moving, how much fuel is left in the tank, what is the crankshaft speed and what is the engine temperature. In addition, the tidy has a lot of bulbs that light up synchronously with the inclusion of certain devices.
  2. Accumulator battery. The battery is an integral element of any car, it allows you to power the equipment of the car when the engine is turned off, and also helps the ignition system to start the power unit. If the battery is discharged, it will not work to start the engine in the traditional way - you will need to either recharge it or try to start from the pusher.
  3. Generating device, failure of which will also lead to the inability to start the engine. This unit provides voltage to all devices and devices used in the car while driving.
  4. Fuse box. This device contains all safety devices designed to protect electrical circuits and devices against overvoltage. If a power surge occurs in the network, then the fuse will take the main blow (by the Ben & Ice Video Master channel).

Common faults

As for breakdowns in the work of the electrical wiring of the product of the Ulyanovsk Automobile Plant, they are as follows:

  1. Battery discharge. As we have already reported, without a battery, normal motor operation will not be possible, the same applies to electrical equipment. Battery discharge can occur for various reasons. Due to the evaporation of electrolyte or its leakage as a result of damage to the battery case, damage to the plates inside the structure, or their short circuit. Usually such problems are caused by wear and tear of the device or its incorrect operation.
  2. Failure of the safety device. Its burnout can occur as a result of wear or a power surge. Before installing a new fuse, ring the circuit to ensure there are no surges. If they do occur, then you need to determine the cause and eliminate it, otherwise the problem will recur.
  3. Broken wire. This problem is relevant not only for UAZ, but also for other cars. To avoid breaks, wires should be routed away from moving body parts.
  4. There is no contact with the device. This usually occurs as a result of a broken wire, but if it is intact, then the problem lies in the contact. The end of the wiring could simply come off or oxidize. Oxidation is one of the main problems in domestic cars.
  5. Failure of the generator. The design of the generating unit itself is quite complex, so there can be many problems in its operation. If the generator itself works, but not correctly, first of all it is necessary to diagnose its belt - it may be overtightened or too loose, in this case the problem will be solved by adjusting it.

Preventive measures

What preventive measures will save the car's electrical network from malfunctions:

  • with the engine off, limit the use of electrical equipment, as the battery will drain faster;
  • from time to time carry out diagnostics of the battery performance and check its charge;
  • provide reliable insulation of the wiring;
  • never use homemade fuses.

The good old UAZ-469 is one of the simplest cars. As if assembled from a children's designer, it is by no means replete with any excesses and bells and whistles. Instead of an air conditioner - the ability to remove the soft roof, and instead of an electrical package - a complete absence of what can be controlled with this package. Nevertheless, there is electrical wiring on this car. Although the same wiring diagram for the UAZ-469 ignition is implemented in the simplest way.

Starter

On a UAZ-469 car, the starter is connected almost directly, through the ignition switch and relay. There is simply no other electronics in the ignition circuit. Even in the more modern "Hunter", which outwardly not every motorist can distinguish from the UAZ-469, the wiring diagram is much more complicated. The control impulse from the ignition relay goes directly to the generator, and all the wiring passes through On the 469, they were used only for the lighting and the generator. In general, the experienced owner of the UAZ-469 simply does not need an electrical circuit. You can understand this car in a few minutes.

Features:

It is worth noting a few interesting features of this car. which will be of interest to those who are driving the legendary UAZ for the first time. For example, the light switch for this machine is located at the feet in the form of a special pedal. We will not judge how convenient it is when driving, we will leave it to those who have already driven the UAZ-469. The wiring diagram for this car is also full of many interesting features that are graceful in their simplicity. Oil level and pressure gauges, for example, went directly to the dashboard and alarm indicator, bypassing the fuse box and other elements. This allows you to repair the car literally "on the knee", being anywhere. It is not for nothing that the 469 is still valued by the military. When repairing the UAZ-469, they do not even need an electrical circuit.

Characteristics

Despite its simplicity, the UAZ-469 already in those years had two fuel tanks and excellent cross-country ability. It was possible to overcome fords, obstacles and bad roads on this SUV without any modifications, but today tuning of various UAZs, including the 469 model, is gaining more and more popularity. Amateurs equip cars with enlarged wheels with mud tires, raise the car and install more powerful motors. True, with the latter option, all the simplicity of the design fades into the background, because you have to completely redo all the electrical wiring of cars. Nevertheless, the popularity of the car is only growing.
