The electrical diagram of the VAZ-2106 machine is necessary for finding faults in the wiring and their quick elimination.

The whole complex of electrical equipment is connected by a single-wire type - the negative terminals of the outputs from the current sources are connected to the “ground” directly to the element that consumes energy. As a result, the "mass" in this scheme VAZ-2106 plays the role of the second connecting wire. The figure below shows a complete view of the vehicle's equipment and wiring diagram.

The VAZ-2106 circuit at the electrical equipment level is especially useful for the owners of this car when it becomes necessary to quickly find a malfunction in the wiring system. Have you adjusted the valves on the VAZ-2109? Check the wires!

In addition, the circuit is often used to evenly connect additional elements and audio devices. If you decide to replace or repair lighting devices, an ignition system and other electrical equipment on the VAZ-2106, using this diagram you will find the required terminal and current source. If you find problems with the engine, first check the tightening torque of the cylinder head bolts, and then check the wiring.

Consider this wiring plan in parts, in which specific parts and elements of the electrical equipment of the machine will be painted.

How are the main elements of the wiring of the VAZ-2106 car protected?

The wiring of the machine is protected with fuses, which are mainly installed in the central and additional unit, located in the lower part of the dashboard on the left side next to the steering column. The circuit from the battery to the terminals and parting is closed when the car ignition is turned on.

Advice: when replacing or repairing lighting fixtures and wiring, be sure to disconnect the battery from the mains. Relays, switches, battery, candles, and even the relay coil in the lighting and fan switching system in the cooling system are not protected by fuses. When the brakes are pumped on the VAZ-2107, a similar problem may arise.

If one of the circuit elements is damaged, the fuse will blow. In the event of a malfunction of the main set of fuses, the backup ones are activated, which are additionally installed next to the ignition unit. If a blown fuse is found, it is not enough just to replace it - you need to study the wiring in detail and find out the reason for the combustion of this part in the VAZ-2106.

The electrical equipment and wiring diagram should help you quickly find and fix faults in the lighting of headlights, dashboard indicators and other systems of your VAZ-2106.

Video: how to read the car wiring diagram

Wiring performs one of the main functions in any car - it ensures the stable operation of the engine and all electrical devices. The presence of malfunctions in the wiring diagram of the VAZ 2106 can lead to the inability to fully operate the machine.

[Hide]

Symptoms and causes of malfunction

To begin with, let's analyze the signs of malfunctions in the operation of electrical circuits.

Signs

What "symptoms" can identify a malfunction:

1. The car will not start or drive. There can be many reasons for a malfunction, starting from a discharged battery and ending with a failed generator device.
2. The car starts up and can move, but some components and systems do not function correctly.
3. On dashboard the vehicle battery indicator came on. The malfunction can be associated both with the battery (discharge, drop in capacity or damage), and with the operation of the generator device.
4. Optics not functioning correctly. The headlights are weak, but they intensify when you press the accelerator pedal. Malfunctions can be caused by a malfunctioning generator.
5. Certain electrical appliances do not work. For example, interior lighting or a heated rear window. The reason may be damage to the circuit wires or a blown fuse. Block diagnostics required.
6. Side direction indicators do not function. The reason must be sought in the electrical circuit and fuses.

Causes

1. Failed battery plates 2. Blown fuse VAZ 2106 3. Broken generator belt 4. Damaged high voltage wires

For what reasons, problems arise in the operation of electrical equipment:

1. Battery discharge or breakdown associated with a decrease in capacity or destruction of the inner plates. Malfunctions may be due to the fact that the battery has worked out its service life. At the end of its useful life, the internal components of the battery wear out faster, especially if the owner of the machine makes mistakes when using the device. When the battery is completely discharged, you can try to charge it, but this does not always solve the problem. If the wear of the device is very large, then after charging the driver will be able to start the engine, but as a result of stopping the car owner will again face a problem.
2. Generator problems. A malfunction of the device may be caused by the failure of one of the structural components of the generator set or wear of its belt. If the diagnostics show that insufficient voltage is supplied to the electrical appliances, and the battery is working, it is necessary to check the generator regulator relay, as well as the integrity of the belt. One of the signs of its wear is power surges and whistling from under the hood. The timing belt cannot whistle like that. To replace the relay controller, you will have to dismantle the device and disassemble it completely.
3. Damage to wire insulation, wire breakage. If the insulating layer on electrical circuits is damaged, it leads to current leakage. Accordingly, electrical appliances will not receive a sufficient voltage level necessary to power them. In the event of a break in the wiring, the operation of the equipment will be impossible. Damaged electrical circuits must be replaced, and if the insulation layer is broken, then the wire must be changed or rewound with electrical tape.
4. Broken contacts. Almost all electrical circuits have connectors for connection. If their contacts are damaged, burned out or oxidized, this leads to the fact that the current cannot flow to the equipment. When oxidized, the elements must be cleaned, this usually fixes the problem. If the pins are damaged, then the only solution is to replace the connectors. But in the event of a burnout, the plugs cannot be replaced. It is necessary to find out the reason, since the burning of the contacts indicates power surges in the electrical network. If the problem is not eliminated, the car owner will constantly encounter it after replacing contacts.
5. Breakage of relays or fuses. All elements located in the mounting block are responsible for the operating condition of electrical devices. If they fail, become damaged or burn out, the equipment will not work. Detailed diagnostics and replacement of failed components is required. Use the diagram on the back of the unit to locate the defective fuse. As in the case of the contacts, the presence of traces of burning on the fuses indicates voltage surges in the on-board network that must be eliminated. If the device is responsible for the operation fuel pump, then its breakdown will make it impossible to start the engine.
6. Malfunction of the ignition lock or other elements of the SZ or BSZ - distributor, starter. With such malfunctions, the engine will not start. If the starter is faulty, the driver will hear clicks when trying to turn on the engine. The dashboard is usually activated, as indicated by the lights on it, but the engine does not start. It is necessary to carry out one by one dismantling of all structural components of the ignition system - lock, distributor and starter. These devices are subject to detailed diagnostics, disassembly and replacement of failed components.
7. One of the causes of electrical malfunction, in which the motor may not start, is damage high-voltage wires ignition systems. We are talking about those cables that are connected to the candles. If they are damaged, sufficient high-voltage discharge cannot be delivered to the spark plugs. This results in problems with starting the engine. If the power unit starts, but the insulation is damaged on the high-voltage wire, then the motor will triple. Problems can be solved by replacing the cables. In more detail, the causes of the problems are shown in the photo.

Practice shows that most malfunctions in the wiring of a car are associated with a poor-quality connection.

You can learn about the nuances of repairing the wiring when replacing one ignition with another from the video shot by Vyacheslav Kravchenko.

In such models, the principle of operation of the electrical circuit when starting the motor looks like this:

1. The driver inserts the key into the lock and then turns it to the “Starter” position. This energizes the device.
2. The generating set starts working. Voltage is supplied from the device to the coil, this element is designed to generate a high-voltage pulse. A low-voltage current is supplied to it, which, as a result of transformation, receives a high voltage. From the coil, the discharge goes to the distributor.
3. By means of high-voltage cables, the device drive begins to push the crankshaft of the car engine. The latter closes the contacts in a certain order, after which a discharge is applied to the candles.

Depending on the type of car, classic or electronic ignition can be installed on the carburetor.

Classic ignition

Such a system is called contactless, it consists of:

• ignition switch, that is, a lock;
• coils;
• distribution mechanism;
• high voltage cables;
• candles.

The function of the switchgear is to interrupt the primary circuit on the module. After that, the mechanism distributes the voltage across the candles in a specific order. Thanks to the coil, the low voltage current is converted into high voltage. The purpose of the candles is to ignite a combustible mixture in the cylinders of an automobile internal combustion engine.

You can learn about the designations of the safety devices on the carburetor version of the car from the video published by the AVTOCLUB_22 channel.

Electronic

If the machine is equipped with electronic system ignition, then a switching mechanism is located in it on the section of the circuit between the distributor device, as well as the coil.

BSZ consists of:

• switching device;
• switch, that is, a lock;
• coils;
• distribution device;
• high-voltage cables through which the discharge is supplied to the candles;
• the candles themselves.

Thanks to the switchgear, control pulses are sent to the switching device, this is done to generate a spark. Then the signals are sent one by one to all spark plugs. The main purpose of the switch is to convert control pulses from a non-contact device into current, the latter being used to feed the primary winding of the coil. This improves the appearance of the spark, which is especially important for power units operating on a lean fuel mixture.

The switching device is diagnosed with a spark. If, as a result of the check, a high-voltage signal is not received at the distributor, this indicates a malfunction of the switch. The device must be replaced. But if, as a result of repair or change, the problem was not solved, then it is necessary to carry out diagnostics of electrical circuits and change the damaged wires. Perhaps the reason should be sought in the increased resistance of the veins, this leads to the fact that the spark will be too weak.

VAZ 2106 with injector

Cars of later years of production began to be equipped with injection power units. We will not consider the wiring diagram of such machines, since it is almost identical to that described above.

On the transfer of "six" from the carburetor to the injector and repair work you can learn how to transfer the wiring from the video from Sergey Kryuchkov.

The wiring diagram for connecting devices in such machines has undergone certain changes:

1. Cars began to be equipped with electric pumps used to increase the pressure level in the rail. AT power units with carburetors, this pressure is absent, they use mechanical pumping devices.
2. The combustible mixture is formed directly in the cylinders of the internal combustion engine. In classic versions of a car, its formation occurs in the carburetor.
3. Electric injectors have been added, they are responsible for fuel injection.
4. Also, the wiring diagram is supplemented by an ECM control module. The device is used to detect the moment at which the injection of a combustible mixture is required. In carburetor versions, it enters the cylinders when the intake valve is opened.

Injection systems are characterized by a large number of electronic components. If the engine does not start, the reason may be not only damaged wiring, but also the sensors are not working.

Instructions for diagnostics and replacement of electrical wiring

If the wiring diagram in the VAZ 2106 is damaged, diagnostics of the voltage level in the on-board network should be performed, this will require a test lamp with two connected wires:

1. One of the "control" contacts is connected to the negative terminal of the battery under the hood of the car. You can use a mass, that is, any metal part of the car body or engine.
2. The second contact is connected to the connection of the diagnosed section of the electrical circuit. It is important that it is located as close as possible to the battery or safety device.
3. If, as a result of connection, the "control" began to burn, then there is voltage in the electrical circuit. This indicates that the diagnosed part of the wiring is in working order.
4. The diagnostic procedure is carried out in the same way for the rest of the wiring.
5. If the check showed that the light does not light up, this indicates that there is no voltage in the circuit. The cause of the malfunction must be sought between this point and the last point where the current was.

The VAZ 2101-2107 channel in the video showed how the battery charge diagnostics procedure is carried out.

Depending on the type of connection, voltage in the circuit may appear only after the ignition switch is turned on.

In case of a short circuit, one of the search options is to dismantle the safety device and connect a tester (voltmeter or multimeter) or "control" to the contacts of its socket. When checking, other components of the electrical system in the diagnosed section of the circuit must be disconnected so that there is no voltage. If you use a test lamp, then after connecting the contacts to the sockets, you must move the wires in different directions. If, during the execution of the task, the lamp began to burn, this indicates that there is a short circuit somewhere in the area. Most likely, the wire insulation has worn out.

Grounding diagnostics are carried out to test the reliability of connecting electrical devices to the mass of the machine:

1. Open the hood and disconnect the battery. One of the contacts of the device that is being tested must be connected to the mass, that is, to the body or metal on the car.
2. The second contact is connected to the junction or grounding point.
3. If, as a result of the connection, the "control" began to light up, this indicates that everything is in order with the ground in the diagnosed section of the circuit.

User Roman Rostovchanin told about the mistakes that should not be made when checking the grounding of contacts.

How to find the damaged section of the wiring:

1. It is necessary to disconnect the voltage from the diagnosed section of the circuit. The wiring section is checked by means of a lamp with a connected voltage source.
2. The two ends of the wire from the light source are connected to different ends of the electrical circuit or to the positive output and the mass of the machine. When the indicator comes on, there are no breaks in the wiring. If the lamp does not turn on, then you need to look for the place of damage.
3. Diagnostics of the ignition lock is carried out in the same way, "control" is connected to its terminals for testing. When the switch is activated, the light source should come on.

If the cause of the malfunction of electrical appliances is the presence of an open circuit, then it is almost impossible to find the damaged area visually, since it is difficult to see oxidation on the contacts or their damage. To solve the problem, you can try to move the connected wire or reconnect the contacts. Sometimes this will fix the problem. As for replacing the damaged section of the circuit, you just need to cut the worn out wire, and connect a new one instead. The junction is sealed or wrapped with electrical tape.

If you decide to completely change the wiring in the car, we recommend that you contact a specialist.

If the malfunction consists in a blown safety device, then such a problem can be determined visually. A break in the wire in the body of the part indicates the need to replace it. When changing devices, use fuses of the same power; the use of spare parts with other ratings is not recommended. The fact is that for different sections of the electrical circuit, a different level of protection is required. The power of the device is indicated on its body. If a part fails, then the cause must be found before it is replaced. Most often, fuses break due to a short circuit, which is associated with an open or worn wiring.

The user Valery Potapenko in his video gave recommendations on finding and replacing failed fuses.

Burnout jumpers can be used in the electrical circuits of the machine. They are used in areas of wiring that are not protected by safety devices, for example, in the circuits of the ignition system. The main similarity between jumpers and fuses is that diagnostics of both parts can be carried out visually. To check, it is necessary to disconnect the battery from the power supply, then dismantle the jumper and assess its condition. If visual diagnostics showed the need for replacement, then the device is changed.

How to prevent malfunctions in the wiring?

What must be considered in order not to encounter malfunctions in the operation of electrical circuits:

1. The procedure for replacing the wires must be carried out with the electrical appliances and battery disconnected.
2. Disconnecting and turning on the battery contacts is allowed only with the ignition off.
3. When checking the wiring, you must not allow a short circuit, this can lead to damage to electrical appliances.
4. Do not use metal tools to remove safety devices.
5. With the engine running, do not disconnect the battery. As a result, the car owner may face the problem of failure of the voltage regulator and other components of the circuit.
6. If the operation of the diode bridge of the generating set is being checked, it is not allowed to use a megohmmeter powered from a network with a voltage of more than 12 volts.
7. When welding the body, the battery and generator must be disconnected. It is also necessary to disconnect the computer from the power supply, if any.
8. Do not repair or replace wiring with the engine off.
9. Periodically recharge the battery and clean its terminals.

The main feature of the VAZ 2106 electro wiring is that it is single-wire. Therefore, it is interesting to look at the wiring that performs 2 roles: plus and minus. It is also important to know that everything that is electrical in the car is designed for a specific workflow.

As for the car itself, many are already familiar with the functionality of the VAZ 2106 car, the space both under the hood and in the trunk. This car can be customized as soon as the user is comfortable. But even this famous car, like the VAZ 2106, can surprise you with something again.

The wiring elements, like any other element that is responsible for the functioning of the car, have their own characteristics in full, and the wiring diagram, in turn:

• activates electrical circuits by using the VAZ 2106 ignition lock;
• connects to the battery through the fuse block;
• conducts electric current of key nodes.

Based on all of the above, all malfunctions should be started from the ignition lock, because most of the responsibility lies with it. The key node itself is not only responsible for controlling the entire ignition system in the car, but also performs a security function. He also allows the towing of the car.

For what reasons do you need to repair the ignition lock

The ignition lock of such a classic car as the VAZ 2106 has 4 modes of operation, which differ in the performance of electrical functions.

1. The zero mode is practically not responsible for anything, it only powers some wires.
2. The first mode makes it possible to operate not only the navigation lights, but also foglights, wiper blades and supports the heating of the car.
3. The second mode is responsible for the operation of the turn signals, dashboard and ignition system.
4. The third position supplies the terminals.

Almost every driver may need to replace the ignition switch once. This can be explained by the fact that some drivers lose their ignition keys, but how to start the car without keys?

Well, if we talk about a classic car, most likely, the driver of the VAZ 2106 has already dealt with the physical wear and tear of some parts, in this case we are talking about the lock larva. If the wires in the ignition already look somewhat suspicious, then the replacement of the wiring should be done as soon as possible so as not to lead the situation to a short circuit.

How to change the ignition switch

In order to replace the ignition switch, you must perform the following steps:

• disconnect the battery;
• unscrew all the screws of the cover under the steering wheel and remove it;
• move the key node to the "0" position;
• insert an awl into the hole to remove the retainer;
• mark contact wiresso as not to confuse them in the future;
• install a new lock and follow the instructions again, but vice versa.

It is convenient that the wiring diagram is made in such a way that in order to change the entire contact group, it is not necessary to remove the ignition lock at all. But in any case, you do not need to actually "rip off" everything with one hand, because you will not be able to install everything removed earlier.

As for the purchase of spare parts, then in this case it must be done from trusted suppliers, because there are enough fakes on the market now. VAZ 2106 is used only to high-quality components. It must be remembered that the body of the original ignition lock is made with care, even at the edges and on top, and the hologram cannot be torn off neatly.

A distinctive feature of a fake will be the smooth and accurate movement of the key in the lock, in fakes it is usually not so easy.

Advantages of contactless ignition

The wiring diagram can be characterized differently. Demon contact ignition is a popular type of tuning for classic car models, and the VAZ 2106 is no exception. This type of ignition has no drawbacks. The main advantage is saving gasoline, the engine runs as cleanly as possible, and the start in winter is smoother, the acceleration of the car becomes more comfortable. But the main advantage is still the smooth operation of the engine.

It is important to know that the smoother the mechanism, the VAZ engine, the farther you can go in this car. And if you know what the circuits are responsible for, then the repair of the main parts can be done by hand.

The wiring diagram of the VAZ 2106 is the same, except for some elements. The sensor here is impulse, it creates vibrations that go to the transistor switch. Due to this supply, other impulses appear that enter the system.

The VAZ 2106 circuit is not as complicated as it seems. There are tons of other tricky surprises in the car, but this is certainly not the wiring diagram. You need to know and understand how important it is to understand what is electrical circuit VAZ and what it affects, as well as whether there are any similarities with other models, for example, with the VAZ 21063. And no matter how old the car is, what year or century it was produced, information about the car will always be relevant.

The wiring diagram of a VAZ can be identical to its other models, like other elements and mechanisms, for example, an engine diagram. It is convenient that spare parts for such cars are sold at every car market, this applies to all electrical equipment. AT classic cars it is very easy to remember what an electrical circuit is, because its analogs are found quite often, therefore, in all "classics", electrical wiring elements can be identical. You should not be afraid of such machines, here all the elements are clear to an ordinary Russian person. Therefore, many do not buy new cars, but are tuning old units and actively using them for many years.

Almost all classic models traditionally have a standard contact-type ignition system (KSZ). An exception is 21065, which uses a non-contact transistor circuit, in which the break of the primary winding power supply circuit is implemented using a breaker mounted in the distributor. Below we will consider in more detail how the VAZ-2106 contact ignition system is arranged and works.

Contact ignition system device

The following components are included in the ignition contact circuit design:

lock (switch);

coil (short circuit);

breaker (MP);

distributor (MR);

regulators, centrifugal and vacuum (CR and VR);

candles (SZ);

high-voltage wires (VP).

Ignition coil (Short circuit) with two windings allows you to get a high current by converting low voltage.

Mechanical breaker (MP) is structurally made together with a mechanical distributor (MP) in one housing - a distributor. It provides opening of the primary short circuit winding.

Mechanical valve (MR) in the form of a rotor with a contact cover distributes current to the candles.

Centrifugal regulator (CR) allows you to change the advance angle (UOZ) in proportion to the crankshaft revolutions. Structurally, the CR is made in the form of two weights. In the process of rotation, they act on the movable plate, on which the MP cams are located.

Vacuum regulator (ВР) makes adjustments to the value of the lead angle (LEO) depending on the load. When changing position throttle (DZ) the pressure in the cavity behind the DZ changes. BP reacts to the degree of vacuum and adjusts the value of the SPL.

Principle of operation and diagram of the contact system

The contact ignition system of the VAZ-2106 works according to the following scheme. When the contacts in the breaker are closed, a low current flows into the primary short-circuit winding. When the contacts are opened, a high current is indicated in the secondary short-circuit winding, which is transmitted through high-voltage wires first to the MR cover, and then distributed to the candles.

An increase in the crankshaft speed leads to an increase in the rotational speed of the CR, the weights of which diverge to the sides under the action of centrifugal forces. As a result, the movable plate moves, increasing the SPL. Accordingly, with a decrease in revolutions, the lead angle decreases.

The contact transistor ignition system is a modernized version of the classic circuit, which uses a transistor switch (TC), included in the primary circuit of the short circuit. Such constructive solution allows you to significantly increase the life of the distributor contacts by reducing the current strength of the primary winding.

Checking the ignition system VAZ-2106

Have a Phillips and flathead screwdrivers, test light or tester, rubber gloves and pliers ready. Before checking contact ignition, apply the parking brake or install the pads under the wheels of the car.

First, carefully check the integrity of all elements of the system, as well as the reliability of the connection of high-voltage wires in all areas. They should fit snugly into their respective contacts.

Turn on the ignition and check the current flow to the system. To do this, connect one wire of the lamp or tester to ground, and the other to the "+ B" contact of the coil. The lamp should be on, and the tester should show a voltage of more than 11 V. Turn off the ignition.

To test the high voltage wire, put on rubber gloves and remove the center wire from the distributor cover. Install a working candle in the cable end, and then press it against the ground with a metal part. Turn the crankshaft on with the ignition on. If at the same time there is a discharge on the candle, then the wire is in good order. In the event that there is no spark, you need to look for the cause of the malfunction in the distributor.

To check the operation of the distributor, remove the cover and inspect it for any damage, as well as the integrity of the carbon contact. If any defects are found, replace the cover with a new one.

Look at the distributor rotor. The runner must not be damaged in any way. Sometimes the rotor body can punch to ground. Also check the functionality of the noise suppression resistor installed in the rotor. If in doubt, it is recommended to replace the rotor.

After that, it is necessary to check the presence of a gap between the contacts of the MP. First, set the crankshaft with a special wrench in a position in which the upper end of the cam of the distributor shaft will be exactly in the center of the textolite pad of the rotary contact lever. Measure the gap between the contacts of the MP, its specified value is 0.35-0.4 mm. Make appropriate adjustments if necessary. After that, check the value of the lead angle.

After completing the above steps and correcting any identified problems or replacing damaged components, start the engine. If in this case the motor does not start, try replacing the capacitor located in the breaker.

Useful Tips

If the noise suppression resistance installed in the distributor rotor has failed, it can be temporarily replaced with a spring from a conventional ballpoint pen.

What to do if a breakdown of the ignition switch or a broken wiring is detected along the way and, as a result, power does not flow to the ignition coil? In this case, you can drive to the nearest service center by connecting the emergency power supply using an additional cable. Connect one end of it to the positive terminal of the battery, and the other to the "+ B" terminal of the coil. However, make sure that there is no arcing. If strong sparking occurs, disconnect the wire immediately. This means that there is a problem with the wiring and this option will not work.
