The design of the wiring of electrical equipment "six"

The main feature that the VAZ 2106 circuit has is that all the conclusions of the nodes and devices with a minus sign are directly connected to the "mass" of the car body. Due to its design, the wiring of the "six" has the following solution.

Considering the features that e. the wiring diagram of the "six", the following point is important: the replacement of any part should be carried out after the negative terminal is removed from the battery. If during repair you touch the terminals and the body of the vehicle with metal tools, a short circuit will occur. Especially for possible emergency situations, regardless of the position of the key in the ignition lock, the following electrical equipment is energized:

email horn chain;
backlight and brake lights;
alarm;
cigarette lighter;
socket.

If you service your vehicle yourself, you periodically encounter the problem of failure of one or another electrical system. Email will help you figure out the breakdown. wiring diagram. Having a VAZ 2106 electrical circuit, you can ring the circuit with a voltmeter, determine the location of the breakdown and repair the equipment.

The search for a breakdown should begin with the ignition switch. This multifunctional device acts as an ignition control mechanism, a car security system and makes it possible to tow the car when the alarm is on.

On VAZ-2103 and VAZ-2106 vehicles, a single-wire circuit for switching on electrical equipment is used. The second wire connecting consumers to sources of electricity is the car body or "mass". The rated operating voltage of sources and consumers of electricity is 12 V. However, the voltage in the electrical equipment system, depending on specific conditions, can vary from 11 to 14.5 V, and within these limits, consumers retain their performance.

The supply voltage to most consumers is supplied through the ignition switch. The power circuits of these electrical components, the operation of which may be required under any circumstances, are always connected to the battery (regardless of the position of the key in the ignition switch). Such nodes include nodes protected by fuse 1 (see table).

The power circuits of most electrical components are protected by fuses installed in plastic block 31. It contains 9 fuses for 8 A and one (1st) - 16 A. The block is located under the instrument panel on the left side of the steering column. The VAZ-2103 also has a 19 to 16 A fuse to protect the fan motor. It is located in a separate housing next to the fuse box. On VAZ-2106 vehicles, there is also an additional fuse box with six fuses, two of which (4th and 5th) are 16 A, and the rest are 8 A. The fuse numbers and the circuits they protect are shown in the table:

№	Protected circuits
1	Plafonds. Sound signals. Plug socket for portable lamp. Cigarette lighter. Stop lamps in the rear lights. Lights signaling open front doors. Watch.
2	Windshield wiper and its relay. Heater motor. Windshield washer.

When a fuse blows, you need to look at the circuits that it protects, fix the malfunction that caused it to blow, and then install a new fuse. It is not allowed to install homemade or any other fuses that are not provided for by the design of the car.

Some electrical systems that require emergency operation are not protected by fuses.

So the engine ignition system is not protected by fuses so as not to introduce an extra element into it, which reduces the reliability of the system in operation. If the ignition system fails, the engine will stop working. The engine start circuit is also not protected so as not to reduce the reliability of the start. In addition, the battery charge circuit is not protected by fuses, since the generator is connected to the battery with a short wire and the introduction of a fuse would complicate the circuit. Also, the windings of the relay for switching on the dipped and main beam headlights are not protected by fuses.

On vehicles, flexible low-voltage wires of the PVA type are used. These wires have flexible polyvinylchloride insulation, resistant to oil, gasoline and operable in the temperature range from -40 to +105°C. The flexibility of the wires is ensured by the manufacture of a conductive core from a large number of soft copper wires. To facilitate the search for the required wire in bundles, the wire insulation is painted in different colors. In addition, strips of different colors can be additionally applied to the surface of the insulation.

When current passes through the wires, the voltage drops and the wires heat up. To ensure that heating and voltage drop do not exceed the permissible limits, it is necessary to select the appropriate cross-section of the conductive conductors of the wires. The greater the electric current flows, the larger the cross section of the wire core should be. Therefore, on cars, wires with different cross-sections of the core are used: 16; 6; 4; 2.5 and 1 mm 2.

The thickest wires with a cross section of 16 mm 2 are connected to the "ground" of the battery and the engine, as well as the starter with the battery. These wires carry the highest current when the engine is started by the starter. The battery and the generator are connected by a wire with a cross section of 6 mm2, since a rather significant current also flows through them when the battery is charging and when the engine is not running, when all consumers are powered from the battery. The rest of the wires have a core cross section of 4, 2.5 or 1 mm 2.

The wires are connected to the units of electrical equipment and interconnected using quick connectors. An exception is the connection of wires to the battery, to the generator terminal "30", to the starter power bolt and to the low voltage terminals of the ignition coil. At these critical connections, the wire lugs are clamped with nuts for maximum reliability of the connections.

To protect the electrical connections from water and dirt, the back of the sidelights is covered with rubber covers. Protective rubber caps cover the lugs of high voltage wires, coolant temperature and oil pressure sensors, the "+" terminal of the battery and the terminal "30" of the generator. The lampholders of the lamps of the side direction indicators and the registration plate lighting lamps are also closed with caps.

To facilitate installation, all wires on the car are bundled. The bundles are connected to each other using plug connectors, which reduces the possibility of tangling wires during installation. There are six bundles of wires in total: front bundle, rear bundle, instrument panel wire bundle, right and left side lamp and side turn signal bundles, and battery wire bundle.

The main bundle of wires is the front. It has three branches. Two of them are located in the engine compartment, and the third is in the cabin under the instrument panel. From the cabin to the engine compartment, the bundle of wires passes through the rubber seal and branches out after exiting it. The right branch of the bundle is laid on the front end shield and the right mudguard of the body, and the left one - on the left mudguard. On the front panel and mudguards, the wires are fastened with steel brackets welded to the body and plastic clamps. The fastening of the bundle should be such that it is not too tight, but also does not hang out, as this can lead to chafing of the wires during shaking and shorting them to ground.

In the passenger compartment, the front beam passes under the instrument panel and has small branches going to the fuse boxes, switches, instruments, ignition switch and other electrical components.

The rear beam runs back along the left side of the body floor and has branches to the interior lamps and to the trunk lamp. The branch to the right ceiling passes behind the rear transverse beam of the body floor. The bundle wires are attached to the body floor with adhesive tape and plastic clamps.

Tips of wires (black), connecting plafonds with "mass", fasten to racks of doors by self-tapping screws. Tips of the wire connecting the sensor of the fuel level indicator to the "ground" are attached under the screws that secure the sensor and the right rear light.

Over the years of production of VAZ-2103 cars, changes were made to their scheme related to the replacement of individual components and aimed at improving the quality of cars and saving wires. Major changes include replacing the foot-operated windshield washer with a power washer and replacing the two-lever switch on the steering column with a three-lever one.

Features of the scheme of cars VAZ-2106

On these cars, compared to the VAZ-2103, a different design of the rear lights and registration plate lights. Two fuse boxes are installed - main 29 (application) and additional 28. Added relay 6 to turn on the dipped headlights. An alarm system has been introduced, including turn indicators using a switch 40 and a relay-breaker 33. There is a separate lamp 67 for monitoring the level of brake fluid and a switch 41 with a control for the degree of illumination of devices.

Recently, small simplifications have been made in the scheme of VAZ-2106 cars. So, at present, one sound signal is installed, and it is turned on directly by switch 43 without relay 24. Lights 48 for signaling the open front door with switch 47 and relay-breaker 66 of the parking brake indicator lamp are not installed. Now, when the parking brake is applied, the control lamp 57 lights up with a constant light.

On VAZ 2106 cars, the wiring diagram includes more than ten different components and modifications of the general network. The owner of the machine needs to understand this issue in order to repair and diagnose the electrical network if necessary.

The development of automobile vehicles is closely related to the evolution of mankind. The formation of transport developed slowly, since a self-propelled car is a complex set of mechanical and electrical elements, where the main components are grouped: body, chassis, engine and electrical wiring, working in perfect harmony with each other. The design and arrangement of these subsystems ensure the efficient functioning of the vehicle, using the design features of the elements and their purpose.

Diagram of the electrical equipment of the car VAZ 2106

The VAZ 2106 car was the real culmination of many years of innovative research and development. It is a machine with reliable mechanical and electrical devices. When developing the VAZ 2106, the specialists of the Volga Automobile Plant were guided by the terms of reference for updating and upgrading previous models to European quality standards. Making changes to the exterior, Soviet designers developed a new design for the rear lights, side direction indicators and other elements. The most popular and massive car VAZ 2106 was put into operation on domestic roads in February 1976.

In addition to changes to the suspension and engine modifications, the specialists paid attention to the electrical wiring in the car, which is a system of colored wires laid side by side and tied together with electrical tape. The electrical circuit is part of the transport and includes a circuit designed to operate the engine and a circuit for transmitting electrical energy to lighting consumers:

engine start system;
battery charge elements;
fuel mixture ignition system;
elements of outdoor and interior lighting;
sensor system on the instrument panel;
sound notification elements;

The vehicle's electrical system is a closed circuit with an independent power source. The current flows through the cable from the battery to the powered component, the current returns to the battery through the metal body of the car, connected to the battery with a thick cable. Thin wires are used for accessories and relays requiring low power.

Using modern developments in design and ergonomics of the location of controls, the plant's specialists supplemented the design of the VAZ 2106 with an alarm, steering column controls for wipers and a windshield washer. To effectively display technical indicators, the instrument panel was equipped with a lighting rheostat. A low brake fluid level was determined by a separate control lamp. Luxury equipment models were equipped with a radio, rear window heating and a red fog lamp under the rear bumper.

For the first time on models of the Soviet automobile industry, the rear lights are combined into a single housing with a direction indicator, side light, brake light, reverse light, reflectors, structurally combined with license plate lighting.

Wiring diagram VAZ 2106 (carburetor)

A complex network of wires runs through the car. To avoid confusion, each wire connected to an individual element has a different color designation. To track the wiring, the entire scheme is reflected in the vehicle service manual. The bundle of wires is stretched along the entire length of the body from the power unit to the luggage compartment. The wiring diagram for electrical equipment is simple and clear, requiring clarification in case of problems with the identification of elements. Color coding is used to facilitate the process of switching electrical consumers, the detailed connection of which is indicated in the diagrams and manuals.

Table: electrical diagram description

The electrical equipment system is made according to a single-wire circuit, where the negative terminals of the power consumption sources are connected to the car body, which performs the function of "mass". The current sources are an alternator and a storage battery. Starting the engine is provided by a starter with an electromagnetic traction relay.

To operate the power unit with a carburetor, a mechanical electric ignition system is used. The order of operation of the system begins with the creation of a magnetic field inside the core of the ignition coil, forming a reservoir for energy, which will be used to spark the spark plugs through high voltage wires.

The activation of the entire process of starting the electrical circuit begins with the ignition switch and the contact group that controls the car's ignition system, lighting system and light signaling.

The main outdoor lighting devices are dipped and main beam headlights, direction indicators, rear lights and registration plate lighting. Two lampshades are used to illuminate the interior. In addition, there are door switches on the pillars of the front and rear doors. The electrical wiring of the instrument panel includes a set of elements to alert the driver about the technical condition of the car: a tachometer, speedometer, temperature, fuel level and oil pressure gauges. Six indicator lamps are used to illuminate the instrument panel at night.

The main characteristics of the electrical wiring diagram:

activation of the electrical circuit through the ignition switch;
switching of current consumers through the fuse box;
connection of key nodes with a source of electricity.

Wiring diagram VAZ 2106 (injector)

A disadvantage of a mechanical ignition system with a carbureted engine is the use of low voltage interruption points on the primary winding of the ignition coil. Mechanical wear of the contacts on the distributor cam, their oxidation and burnout of the contact surface from constant sparking. Constant adjustment to compensate for wear on the contact switches eliminates mechanical changes. The power of the spark discharge depends on the state of the contact group, and poor sparking leads to a decrease in engine efficiency. The mechanical system is not able to provide sufficient component life, limiting spark power and engine speed.

To solve the problems of the mechanical ignition system, electronic ignition has been introduced. In the original systems, contact switches were replaced by a Hall effect sensor that responds to a rotating magnet on the camshaft. The new cars removed the mechanical ignition system, replacing it with an electronic system with no moving parts. The system is fully controlled by the on-board computer. Instead of an ignition distributor, an ignition module has been introduced that serves all spark plugs. Along with the development of transportation technology, vehicles have been equipped with a fuel injection system that requires precise and powerful spark generation.

The injection system on the VAZ 2106 for supplying fuel has been installed since 2002. The previously used mechanical sparking did not allow improving the performance of the motor. The updated power supply circuit of the injector uses an electronic control circuit for the operation of the entire system. The electronic unit (ECU) controls many processes:

fuel injection through nozzles;
control of the state of the fuel;
ignition;
exhaust gas condition.

The functioning of the system begins with the readings of the crankshaft position sensor, which signals the computer about the spark supply to the candles. The electronic circuit of the injector differs from the carburetor model, assuming the inclusion of various electronic devices in the vehicle system that transmit signals about physical and technical parameters. Due to the presence of numerous sensors, the electronic circuit of the injector works steadily and stably. After processing all the signals and parameters from the sensors in the internal memory of the microcontroller, the operation of the fuel supply actuators, the moment of spark formation, is controlled.

Underhood wiring

The main part of the electrical wiring is located in the engine compartment, where the main elements, electronic and mechanical sensors of the car are located. A significant number of wires reduce the overall aesthetic appearance of the motor, surrounded by a plurality of cable wiring. For convenient maintenance of the mechanical components of the engine, the manufacturer puts the wiring in a plastic braid, eliminating its chafing against the metal elements of the body and hiding it in the body cavities out of sight so that it does not distract attention from the power unit.

Under the hood on the engine there are many auxiliary elements that consume or generate electrical energy such as a starter, generator, sensors. All devices are interconnected in a certain way and in the order reflected in the electrical circuit. The wires are fixed in a safe and inconspicuous place, which prevents them from winding up on moving parts of the chassis and motor.

There are ground wires inside the engine compartment, which should only be tightly connected on a smooth metal surface. A reliable grounding contact through the car body provides a single reverse current circuit from the negative terminal of the battery, which is the "mass" of the vehicle. The bundled cables from the sensors are placed in a protective casing that provides insulation from heat, liquids and radio interference.

The wiring system located in the engine compartment includes:

battery;
starter;
generator;
ignition module;
high voltage wires and spark plugs;
numerous sensors.

wiring harness in cabin

With electrical wires, all sensors, nodes and dashboard function as a single mechanism, providing a single task: the uninterrupted transmission of electrical signals between interconnected elements.

Most of the elements of the vehicle are located in the cabin, providing process control, monitoring their implementation and diagnosing the technical condition of the sensors.

Automotive system controls located inside the cabin include:

instrumentation panel and its illumination;
external lighting elements of the roadway;
signaling devices of turn, a stop and the sound notification;
interior lighting;
other electronic assistants such as windshield wipers, heater, radio and navigation system.

The wiring harness in the passenger compartment provides the connection of all elements of the car through the fuse box, which, regardless of the number of devices, is the main element of the electrical wiring in the passenger compartment. The fuse box, located to the left of the driver under the torpedo, often caused serious criticism from the owners of the VAZ 2106.

If the physical contact of any wire is lost, the fuses overheat, burning the fusible link. This fact was the presence of a problem in the electrical circuit of the car.

The wiring harness is laid under the carpet, passing through technological openings in the metal body of the vehicle from the dashboard to the luggage compartment.

Features of maintenance of electrical equipment and replacement of wiring VAZ 2106

Properly laid wiring around the perimeter of the cabin and under the hood does not require special attention and maintenance. But, after repair work, the cable can be pinched, its insulation is damaged, which will lead to a short circuit. Bad contact will lead to heating of the cable and melting of the insulation. A similar result will be with improper installation of instruments and sensors.

The long period of operation of the vehicle affects the condition of the insulation of the wires, which becomes hard and brittle, especially under the influence of significant heat in the engine compartment. Damage caused by broken wires is not easy to find. If the damage is in the public domain without a braid, the repair is carried out without dismantling the wires.

When replacing one wire, mark the ends of the wire in the blocks with labels, if necessary, make a connection drawing.

The main stages of wiring replacement:

a new wiring harness for the VAZ 2106 model;
disconnected battery from the car network;
analysis of the instrument panel;
analysis of a torpedo;
removal of seats;
removal of soundproofing cover for easy access to the wiring harness;
clean corrosion that can cause poor contact;
at the end of the work it is not recommended to leave bare wires.

The wiring replacement procedure should not be carried out without an electrical circuit for connecting devices in order to avoid confusion during installation work.

When replacing a single wire, use a new one of the same color and size. After replacement, test the corrected wire with a tester connected to the nearest connectors on both sides.

Precautionary measures

Before performing work, disconnect the battery and isolate the sharp edges of the technological holes in the car body in places where the wires will pass in order to prevent a short circuit.

Malfunctions of electrical equipment VAZ 2106

Eliminating problems with electrical elements requires special skills and following simple rules:

the system requires a power source;
electrical devices require constant voltage;
the electrical circuit must not be interrupted.

When you turn on the washer, the engine stalls

The windshield washer is equipped with a switch that controls the fluid supply motor. A stalled engine malfunction can be caused by grounding the power cable, a corroded terminal, dirty and damaged wires. To troubleshoot, it is worth checking all these elements and eliminating the shortcomings.

Malfunctions of the contact ignition system

Possible causes of malfunctions are:

burning / oxidation of the contacts of the ignition distributor (distributor);
burning or even partial destruction of the ignition distributor cover;
burning of the contact of the runner and its wear;
failure of the runner resistance;
capacitor failure.

These reasons impair the performance of the engine, affecting its start, especially during the cold period. One of the recommendations is to clean the contact group of candles and the slider. If this reason occurs, the distributor contacts must be replaced.

Worn ignition cover causes damage to the runner. In this case, the parts must be replaced.

Another reason is a malfunction of the noise suppression capacitor of the ignition distributor. In any case, the part must be replaced.

The wear of the mechanical part of the distributor causes the shaft to beat, which manifests itself in various contact gaps. The reason is bearing wear.

Ignition Coil Malfunctions

Starting the engine is complicated by a malfunction of the ignition coil, which begins to heat up significantly when the ignition is off due to a short circuit. The reason for the breakdown of the ignition coil is that the coil is energized for a long time when the engine is not running, which leads to shedding of the winding and its short circuit. A defective ignition coil must be replaced.

Schemes of electrical equipment of individual branches

The electrical equipment of the VAZ 2106 has undergone minor changes. On the car there was a sound signal without a switch-on relay, a rear fog lamp. On cars of luxury modifications, a rear window heating system was installed. Most current consumers are connected through the ignition key, which allows them to work only when the ignition is on, preventing accidental shutdown or battery drain.

Auxiliary elements work without turning on the ignition when the key is turned to position "I".

The ignition switch has 4 positions, the inclusion of which excites current in specific connectors:

in position "0" from the battery are powered only by connectors 30 and 30/1, the others are de-energized.
in the “I” position, the current is supplied to the connectors 30-INT and 30/1–15, while the “dimensions”, the windshield wiper, the fan heating system of the heater, running lights and fog lights are energized;
in position “II”, contact 30–50 is additionally connected to the previously used connectors. In this case, the ignition system, starter, panel sensors, and “turn signals” are included in the circuit.
in position III, only the car starter is activated. In this case, the current is available only to the 30-INT and 30/1 connectors.

Scheme of the speed controller of the electric motor of the stove

If the car heater does not function efficiently enough, then you should pay attention to the stove fan. Automotive heating technology is simple and accessible for analysis.

Table: wiring diagram for the interior heater fan

The problem may be a bad connection, which causes the fan to stop working.

Contact ignition circuit

Table: scheme of the contact ignition system VAZ 2106

Contactless ignition circuit

The installation of a contactless ignition system is an innovative option when modifying the VAZ 2106 model. From this innovative approach, an even rumbling of the engine is felt, failures are eliminated during a sharp increase in speed, and starting in a cold period is facilitated.

Table: contactless ignition system diagram

The main difference between the non-contact system is the presence of a pulse sensor installed instead of a distributor. The sensor generates pulses, transmitting them to the commutator, which generates pulses as in the primary winding of the ignition coil. Further, the secondary winding produces a high voltage current, passing it to the spark plugs in a certain sequence.

Scheme of electrical equipment of the dipped beam

Headlights are an important safety feature responsible for improving the visibility of vehicles day and night. With prolonged use, the light-emitting thread becomes unusable, disrupting the operation of the lighting system.

Loss of lighting affects night driving. Therefore, a lamp that has become unusable should be replaced to increase illumination. In addition to lamps, switching relays and fuses can become the causes of a malfunction. When troubleshooting, include these items in the inspection list.

Wiring diagram for direction indicators

When creating the VAZ 2106 model, the designers included an alarm system in the list of necessary elements, which is activated by a separate button and activates all turn signals.

Table: symbols of the direction indicator circuit

There are no particular difficulties in working with the electrical system of a VAZ 2106 car. Constant careful care and care for the cleanliness of contacts is required. It is important to do everything competently and accurately, prolonging the life of important components and assemblies.

The modification range of the VAZ 2106 family includes:

VAZ 2106, 21065-00 - equipped with a model 2106 engine;
21061, 21065-01 - equipped with a model 2103 motor;
21063 - there was an engine from 21011.
Car brand 21065 is a luxury variant of this family. It has the following differences from the 2106 model: equipped with a five-speed gearbox and final drive with a gear ratio of 3.9. Some cars were equipped with a Solex carburetor and a contactless ignition system. The electrical equipment of the car is supplemented by an electrically heated rear window, halogen headlights and an anti-fog taillight. The body has been modified: the upholstery and headrests of the seats have been updated; the car is supplemented with model 2105 bumpers. Spare parts for the presented vehicles are everywhere. In addition, a kind of "novelty" is, so to speak, the trends of the 21st century make themselves felt. Thanks to this, car maintenance and repair is not a big problem.

Ignition scheme VAZ 2106

Includes ignition distributor, coil, spark plugs, lock, and low and high voltage wires. The connection diagram of the VAZ 2106 of this car system is shown in the photo.

Until 1980, machines of this brand were equipped with the R-125B distributor. It was installed in conjunction with 2103 type carburetors. This distributor had a mechanical octane corrector, with which it was possible to slightly change the ignition timing, however, at the same time, there was no special vacuum regulator. After 1980, when the engines were equipped with carburetors 2107-1107010-20 ("Ozone"), they began to use the distributor 30.3706, which had a vacuum ignition timing controller.
The coil used was of type B117-A. There was an open magnetic circuit. The device is oil-filled, sealed.
Candles of the A17DV type or similar ones, but of foreign production, were used.
Cars were equipped with a VK347 lock, which had an anti-theft device. It works as follows: when the key is removed (from position III "Parking"), the locking rod is pulled out of the switch body in a special way. It enters the groove of the steering shaft and, thus, the shaft is blocked.

It is recommended that you always carry with you, if you are the owner of a car 2106, an ignition distributor capacitor and an ignition coil. The probability of their failure is quite high, it is impossible to replace or repair them using some other devices.

If the coil or capacitor is damaged, it will be impossible to start the engine, but replacing failed devices is very simple. For example, the ignition switch (shown in the video). If an emergency arises, they can be replaced with similar devices from other car models.

Fuse diagram VAZ 2106

The VAZ 2106 fuse circuit is one of the simplest. It presents two lines with automotive fuses. This design is fastened with two nuts to the machine body. If you need to remove the fuse line, you will have to disconnect the battery. The disadvantages of this in its uncomfortable lids.

The main disadvantage is that due to the unbending legs, contact sometimes disappears. And in some cases, due to poor contact, the fuse heats up and, as a result, the plastic ruler melts. This disadvantage can be easily corrected by replacing the fork-shaped fuse box. It will take 10 minutes, but in the future, thanks to this "", you will get rid of various troubles that are associated with electricity.
