A typical wiring diagram for a VAZ 2106 is made taking into account the single-wire principle of connecting elements of the vehicle's electrical equipment. This means that the negative contacts of electronic devices are connected to the so-called. "mass" vehicle, and the wired connection provides only positive terminals.

Car electrical wiring device

This principle of integrating electronic components into the electrical circuit of a vehicle is translated into practice in the following type of connections:

1. The vehicle's current electrical circuits are activated through the use of the ignition switch.
2. Electronic devices that ensure the maintenance of the required degree of safety during vehicle operation are connected to the battery through a safety unit.
3. The body parts of all “six” units are good conductors of current.

Important: when carrying out repair and maintenance work on a car, it is necessary to de-energize the electrical wiring by removing the negative wire from the battery terminal, otherwise unauthorized contact with the battery contact with a tool can lead to a short circuit. For clarity, the electrical diagram. VAZ 2106 wiring diagram is posted on our Internet resource, and car enthusiasts can use it to carry out the necessary tests.

When independently servicing a vehicle, it is necessary to determine the cause of a particular defect in the electrical components of the “six”. Troubleshooting should begin with the ignition switch, which is intended for:

• control the functionality of the ignition system;
• coordinating the operation of security systems and preventing car thefts;
• towing a “six” with a working emergency light.

In a VAZ 2106 car, the wiring diagram includes the following elements:

• Battery with negative wire contact on the vehicle body;
• starter with connector “50” from the ignition switch through the start relay;
• generator device;
• safety block;
• ignition switch;
• regulator relay.

The principle of operation of electrical equipment of the VAZ 2106

The ignition switch has 4 positions, when each of them is activated, certain connectors and contacts are switched:

1. In position “0”, the battery current is transmitted only to connectors 30 and 30/1, the others are de-energized.
2. In position “I”, current is supplied to connectors 30-INT and 30/1-15, while the “dimensions” and the purifier are energized windshield, fan heating system of the heating complex.
3. In position “II”, contact 30-50 is additionally connected to the previously used connectors. In this case, the ignition system, starter, panel sensors, “dimensions” and “turn signals” are included in the circuit.
4. In position “III” only the “dimensions”, horn and windshield and stern wipers are activated. In this case, the current is available only to connectors 30-INT and 30/1.

A number of cars of this brand are equipped with such devices as a rear window heating complex, an electric windshield washer, a light relay, etc. The power supply to these gadgets is supplied via a separate line through the ignition switch at the key positions “I” and “II”.

Important: because Since the washer tank is made of PVC material and is a dielectric, the electric motor is additionally equipped with a negative wire and when working with it, it is necessary to use dielectric protection on the connectors.

In the “six”, the following power circuits operate in constant mode under current: horn, brake lights, emergency lights, cigarette lighter socket, “carrying” plug, instrument lighting. The leading circuits of the electrical equipment of vehicles are subject to protection by fuses, which are located in two special blocks (main and spare), located on the driver’s side under the dashboard.

One of the elements of the VAZ 2106 wiring diagram is a safety block, the design of which does not meet modern requirements for the maintenance of electronic equipment. Flaws:

• an unstable connection between the fuse and the socket leads to the appearance of burnt spots;
• during operation, the safety element is subject to heating, which negatively affects the nearby fastening sockets;
• the low cost of replaceable fuses does not guarantee their reliability, so checks of this unit should be carried out regularly.

Using the so-called "bugs" can lead to a vehicle fire, because there is a high probability of committing a short circuit. There is a completely safe option for upgrading standard products, in which blade fuses must be installed, the seats of which are perfectly integrated into the safety block.

Advantages of blade fuses:

• stable contact of the product with the mounting location;
• the fusible type element is sealed in a transparent PVC casing;
• dynamic heat dissipation due to the increased contact area.

Important: the “six” generator unit, the wiring to it, as well as to the battery, starter, bobbin, optics relay and some other elements are not equipped with safety elements.

The VAZ 2105 model first appeared on city streets in 1980 and immediately became extremely popular. The fact is that the design of the car repeated the features of European models of those years: front and rear headlights, aluminum bumpers, and a modern instrument panel.

All this required the designers to rework the usual electrical circuit of the car.

The original diagram published in the article will make it easier for car owners and service station technicians to find faults in the electrical system of a Zhiguli family car..

The VAZ 2105 wiring diagram together with a verification tester will allow you to:

1. determine the causes of circuit failure;
2. identify which sensor or relay has stopped performing its functions;
3. establish a breakdown in the ignition system;
4. identify the circuit whose fuse has blown;
5. check the on-board voltage supplied by the generator;
6. find the cause of failure of incandescent lamps, etc.

The VAZ 2101 platform was taken as the basis for production. At its core, it was the same rear-wheel drive five-seater sedan car. The VAZ 2105, with its design, practically copied the models of cars produced in Europe in the early 80s, and cost an order of magnitude lower, which predetermined its popularity in Western countries.

Abroad, the car was named Lada Riva and Lada Nova (depending on the country of sale). Under these names he was shown in video advertisements.

The car plant produced several modifications of the VAZ 2105:

1. With the VAZ-2105 index, the car was equipped with a 4-speed gearbox. gearbox and carburetor engine volume 1290 cc. cm (63 hp);
2. The VAZ-21050 was equipped with a 5-speed checkpoint;
3. The VAZ-21051 was equipped with an engine from the VAZ 2101 (volume 1200 cc, power 58 hp) with a 4-speed. checkpoint;
4. The VAZ-21053 was equipped with a VAZ-2103 carburetor engine (volume 1450 cc, power 71 hp);
5. VAZ-21053-20 was completed injection engine from VAZ-2104 (volume 1450 cc, power 71 hp), meeting Euro-2 requirements. It also came with 5 tbsp. Transmission.

For reference: the electrical wiring of the VAZ 21053 was distinguished by a different form of terminals in the engine compartment. This was caused by the installation of the ECM -electronic system engine control and additional sensors.

Features of the electrical equipment of the VAZ 2105 car

The electrical equipment of the VAZ-2105 car is made according to the classic single-wire circuit for the Zhiguli family, in which:

1. the metal body of the car plays the role of a second wire;
2. negative conclusions of all electrical devices and components are connected to ground;
3. electrical circuits are protected by fuses;
4. the operation of the main systems is activated through the vehicle's ignition switch.

For reference: the ignition switch controls electrical networks by supplying power from the battery or generator.
The contact group of the lock is designed in such a way that when the engine starts, the electrical wiring of the VAZ 2105 secondary circuits is turned off.

Egnition lock

As a control system electrical systems The car used an ignition switch that had four main positions:

1. Position “0” – everything is off.
2. Position “1” – ignition is on. The key is locked in the lock, and with the key inserted, external lighting circuits, control devices and alarm lamps (level brake fluid, engine oil pressure, fuel level in the gas tank);
3. Position “2” – turning on the starter. Auxiliary circuits and VAZ 21053 wiring that connects them do not work to facilitate engine starting;
4. Position “3” – parking. All circuits are turned off, and after removing the key, the steering column is locked.

For reference: the factory instructions inform you that, regardless of the position of the key, the interior lighting lamps, brake light lamps (when the brake pedal is pressed), the horn and the connector for connecting a portable lamp remain energized.

Fuse and relay box

To protect electrical circuits and devices, a fuse circuit is used to break the electrical connection. This happens when the voltage increases - the fuse-link melts due to temperature and the circuit is disconnected.

The photo shows:

1. From 1 to 17 – fuses;
2. Relay 18 is responsible for turning on the low beam headlights;
3. Relay 19 is responsible for turning on high beam headlights;
4. Relay 21 activates the headlight cleaner and washer;
5. Relay 22 is responsible for turning on the heating rear window.

For reference: under No. 20 the jumper is indicated. The wiring diagram of the VAZ 21053 in the export version is distinguished by the installation of a relay for turning on sound signals in this place.

Legend domestic auto industry, VAZ 2101, took over almost all the best features from its Italian donor, and in some ways it became even more advantageous to differ from the Fiat 124. As a result of test drives, some shortcomings in the design of the Italian car were revealed, and only Soviet roads heroically helped to identify, eliminate and improve the design of the penny to the proper level

These changes also affected the electrical equipment of the VAZ 2101, in particular, the location of some electrical appliances. We found a real factory electrical diagram for a 1970 Zhiguli, and we are happy to provide it for study.

The sources of electrical energy are the generator and, which are connected in parallel. A voltage of 12 volts is considered nominal, but its value may fluctuate depending on engine operating conditions. At high engine speeds, the voltage in the network can reach no more than 14 volts, and at low speeds - no less than 11. All electrical appliances that are installed on board the car are designed for this voltage range and can operate at these values ​​without interruption.

To adjust the voltage generated by the generator, a relay regulator is provided in the circuit. Its responsibilities include monitoring the voltage at the output of the generator, and when the readings drop, the relay sends a signal to the control lamp located on the instrument panel. At low voltage, it may discharge prematurely and not have time to recharge, which can damage it. If the charging voltage is too high, the electrolyte may boil, which will also not lead to anything good.

Fuse box VAZ 2101

If short circuits occur in the circuit during vehicle operation, the current strength in the damaged area increases. If the damaged circuit is not disconnected from the network, it can very quickly drain the battery, the wires can overheat, which will cause a greater likelihood of a fire, melting the wires and the upholstery of the car. In order to avoid this, the entire electrical wiring diagram is divided into ten zones, the state of which is controlled by a specific fuse.

The fuses are collected in a single block, numbered, and we can know exactly when a certain fuse blows in which circuit the short circuit occurred. This can be tracked both by the diagram and by the indicators on the body of the fuse box cover.

VAZ 2101 car relay

Some electrical devices of the VAZ 2101 have quite serious power, consume large currents, and in order to protect the switch contacts from overloads, relays are used in the electrical circuit. Only electromagnetic relays were installed on the penny, and most of them were located under the hood of the car. Only the turn signal relay was installed under the instrument panel. The following were installed on the hood:

All relays on the VAZ 2101 car cannot be repaired, and in case of failure they are replaced with new ones.

On the VAZ 2101 car it was installed contact system ignition, which was distinguished by its simplicity and reliability. Still, some elements require special care, and this primarily applies to the distributor.

If there is no spark at the spark plugs, we can confidently say that the distributor is involved. The sore spot of the contact distributor was the cover, which tended to develop microcracks. They could not be identified visually, but voltage leaked through them and a spark struck the housing. This can only be checked on a special stand, or in complete darkness, when sparks from the distributor cover are visible.

There is nothing complicated about the electrical circuit of a penny, you just need to know it, then any trouble with electrical equipment can be easily detected. Respect your 2101 and good luck on your journey!
