Everything you need to know about fuses on the VAZ 2106

VAZ 2106 fuse box pinout, diagram

If you have any problems with electrical equipment: the low or high beams have disappeared or are not working, the turn signals, stove, cigarette lighter, fan, wipers are not working, the signal has disappeared, etc., then this could all be the reason that the fuse has blown. This means it needs to be replaced.

To do this, you need to know the location of the mounting block. And it is located under the steering wheel, on the left side. In order to understand what the VAZ 2106 fuses are responsible for, you need to look at the simple pinout of the old fuse block (FB) and see the description below.

Table “VAZ 2106 fuse designations”

Relay for high and low beam "six"

As already mentioned, the standard high and low beam relays of the VAZ 2106 are absolutely identical, have similar catalog numbers (90.3747-10 or 113.3747-10), are of the same type as the initiation relay for the radiator fan device of the cooling complex of the power plant and can be replaced with each other friend.

To connect the light relay to the VAZ 2106, devices with item number 113.3747 are used, which are installed in a mounting-type block device. Similar devices are installed in the system to turn on the EDC fan device, heat the stern glass and produce alarm sounds.

The initiation voltage of the device at an average temperature of about 23 °C is within 8 V, and the resistance of the device winding at a temperature of 20 °C is 85 ± 8.5 Ohms.

Instead of products under catalog number 113.3747, it is allowed to use updated high and low beam relays VAZ 2106 90.3747-11 in a plastic case and with increased dimensions. It is also allowed to replace products 113.3747-10 with a mounting bracket with gadgets with fasteners under the nomenclature value 90.3747-10 with the same characteristics.

The automotive industry practices the production of light relays for the VAZ 2106 under the nomenclature numbers 902.3747 (version 11 - without fasteners and 10 - with fasteners), used on injection "sixes", because The device integrates an additional resistance to suppress interference, connected in parallel to the relay winding. For such high and low beam relays, the resistance between connectors “85” and “86” is 65 - 80 Ohms. They are interchangeable with the VAZ 2106 light relay with numbers 113.3747.

The following shows the location and designation of each factory relay:

1. Voltage regulator, which is responsible for proper charging of the battery. Located on the left mudguard.

4. Low and high beam headlights. They are also located on the right mudguard. They are identical and interchangeable.

5. Turn and hazard warning relay. It is located behind the instrument panel, approximately behind the tachometer.
6. The wiper relay is located on the left side, under the instrument panel.

The video below clearly shows where which relay is located.

Replacing the light relay on the “six” - work order

The “six” light acquires special importance when a motorist has to drive in conditions of poor visibility, in difficult weather conditions and at night.
However, any driver must remember that defects in the vehicle’s electrical equipment system, one way or another, affect the functionality of the power plant. And this is despite the fact that the main electrical circuits are protected by relay elements, just as the lighting of the “six” is protected, the safety devices of which are routed to the vehicle’s fuse box. On the VAZ 2106, the headlight relays, along with other main electrical equipment of this vehicle with high current consumption and high voltage, are connected via relay elements. The main purpose of the VAZ 2106 light relays, whose price is low, is to protect the switch contacts from energy overload.

Car enthusiasts often ask where the high and low beam relays are located on the “six” and what they look like. Let us explain that almost all relay devices, as well as the relay - voltage regulator, are located in the power plant compartment. The exception is the turn signal and hazard warning relays, which are located under the instrument cluster in the car interior, covered by a front panel. Both relays are identical in appearance (they can be easily found on the mudguard on the right as the car moves) and are located next to the battery charging indicator relay.

The electrical diagram of the light relay is located below:

On the general diagram of the electrical equipment of the “six” you can see at number 5 the VAZ 2106 low beam relay, and at number 6 the VAZ 2106 high beam relay, which are interchangeable elements. Also here you can see the integration of the main electronic devices of the vehicle into the general electrical supply circuit of the vehicle of this modification.

Below is the pinout of the new type of power supply or, as people say, “Euroblock”. The diagram also shows which fuse is responsible for what.

Replacing the "six" light relay

Russian car enthusiasts driving Zhiguli “classics” ask the question of how to connect a light relay to a VAZ 2106 so that it can function without problems in the future. Similar work is carried out when replacing the “six” light relay.

The work is carried out in the following sequence:

1. We unscrew the fasteners and dismantle the headlight relay for subsequent replacement;
2. We remember the frequency of connecting electrical wiring or mark them with a marker. Remove the wiring from the device connectors;
3. We install the updated device in the reverse order.

Replacing the VAZ 2106 fuse box with a “Euroblock”

And finally, for those who don’t know how to replace the old model with a “Euroblock”, the following information. There is nothing complicated here.

You just need to follow the instructions below:

1. First you need to disconnect the minus from the battery.
2. Use a 10mm wrench to unscrew the old power supply. In this case, the wires are not disconnected.
3. According to the diagram above, wires and jumpers are installed.
4. It is important to install jumpers only on those wires that carry voltage from the engine compartment.
5. Jumpers are installed between pins 3-4, 5-6, 7-8, 9-10, 11-12.
6. Next, the wires are removed one by one from the old device and attached to the Euroblock.
7. At the end, check that the connection is correct (for example, with the low beam on, if you pull out the 5th fuse, the left headlight should go out).
8. All other circuits are also checked.

The video below clearly shows how to replace an old power supply with a Euroblock.

Location and electrical diagram

The power supply itself consists of two lines with fuses, which is installed in the car interior and attached to the body with two nuts. In particular, it is located on the driver's side under the instrument panel. Below is a diagram of the device, as well as the purpose of each element.

As you can see, almost all circuits of a domestically produced car are protected using fusible devices. However, there are exceptions here too. In particular, we are talking about:

• starter retractor relay - it is missing;
• the power circuit of the relay coil, which ensures the operation of the radiator fan of the cooling system, is also not protected;
• the ignition coil is also not protected by a relay;
• If your car has an old-style power supply, then it does not have a power supply circuit for the switch and a Hall sensor.

The element installed in the power supply is designed for a certain voltage in the wiring. This voltage is calculated using a simple formula - the voltage of all energy consumers in the wire must be multiplied by the reserve number, ranging from 1.2 to 1.5. So what's the purpose? In order for the operation to be stable, the nominal values ​​of the block elements must match.

It should be added that very often owners of 2106 make mistakes by using an ordinary coin instead of a fusible device. It is better not to do this, since a short circuit may occur in your car at any time. Therefore, old-style power supplies, like any other machine component, also require periodic maintenance. Due to design features, that is, weak power supply holders or tips that regularly oxidize, you may notice the contact part burning.

Thus, due to the increased contact resistance, overheating occurs and the contact condition of the element deteriorates. This may result in additional problems with the vehicle's wiring. To prevent this from happening, you should periodically, at least twice a year, inspect the power supply unit as a whole. Clean the mounting sockets, inspect the power supply and promptly replace failed fuses.

But this all applies to old-style power supplies. Some owners of these car models, taking into account the periodic problems with the old-style power supply, change it to a new one.
