Installation of blade fuses in VAZ 2101, 2103, 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”

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.

Description and purpose of each fuse block of the VAZ 2106 car

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.

Typical symptoms of a faulty fuse

• The fuse has changed color, pinholes are visible, the predominant color is black. A symptom characteristic of old-style modules. The new ones don’t have this, the design is different;
• An indicator on the dashboard indicates a malfunction of one or another equipment;
• The mechanisms are not active when the engine is running, the ignition is on, and the battery is working;
• A burning smell can be heard in the cabin, emanating from the place where the power supply unit is fixed;
• The modules feel hot to the touch, with an unnatural temperature.

Replacement

The fuses are secured with spring terminals. There are two types: black (8 amps) and green (16 amps).

The burned out element looks like this:

1. Using a screwdriver, remove the cover.

2. We press out one of the terminals, remove the burnt-out element and put a new one of the same rating in its place.

3. We put the cover in place.

The replacement process is carried out in a similar way in the additional block.

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.

What fuse is responsible for what on the VAZ-2106

Quite often, VAZ-2106 car owners have to repair electrical equipment in their car. And such a breakdown is most often caused by malfunctions in the fuse circuit, which can simply lose contact with the plate conducting the current. Many car owners have already been able to see from their own experience that the design of fuses, to put it mildly, is not very reliable, because the elements can fail as soon as the resistance in the circuit increases a little. Then they begin to get very hot, which will lead to deterioration and even complete loss of contact. In addition, it is worth noting that damage can also occur if the pressing force of the plate that holds the fuse weakens. Moreover, if the breakdown is caused by this reason, then it will be quite dangerous. The fact is that if there is a bad contact on the fuse, the element may simply not work when a short circuit occurs, and it will inevitably heat up. As a result, a failed element can cause the entire circuit to catch fire, and at the most inopportune time.

What should a driver know about fuses?

Every car owner should know the most important information about fuses in order to identify the cause of a breakdown in a car system that refuses to respond to the driver’s order:

1. If the fuse fails, replacing this element with an improvised item, for example, a screw or screw, is under no circumstances allowed, since such actions often lead to a fire.
2. After the fuse trips, you need to find out which circuit it is responsible for:

• cigarette lighter;
• light or gas;
• turn signals.

And only after this should the cause of the burnout of the failed element be eliminated. Before installing a new one, be sure to clean the so-called socket of dirt and insulate the wiring.

1. If upon inspection it is noticed that the failed fuse has melted, then most likely there is a short circuit in the circuit. And if the plastic insert starts to melt, then you need to check the reliability of the contact in the “socket” itself.

Experts strongly recommend using your own personal fuse for each automotive consumer, and it is best to use Euro elements, as they are much higher quality and more reliable.

Fuse box in the passenger compartment

Despite the lack of differences between the mounting blocks of the “sevens” with carburetor and injection engines, the latter are equipped with an additional block, which is installed in the cabin under the glove compartment. The block consists of blocks with relays and fuses:

• main relay;
• fuel pump relay;
• fan relay.

Fuses are designed to protect:

• main relay;
• electric fuel pump;
• electronic engine control unit.

Fuse and relay box in the passenger compartment: 1 - fuse protecting the power circuits of the main relay; 2 - main relay; 3 - fuse protecting the constant power supply circuit of the controller; 4 - fuse protecting the power circuit of the electric fuel pump relay; 5 — electric fuel pump relay; 6 — electric fan relay; 7 - diagnostic connector

Replacing fuses

Before replacing fuses there are two things you need to do:

• turn off the ignition;
• disconnect the ground from the battery.

Otherwise, a short circuit may occur during operation.

The procedure is as follows:

1. remove the fuse box cover by releasing the fasteners;
2. inspect the fuses and determine those in need of replacement (this can be seen by a broken fusible thread or black traces of its combustion);
3. remove the fuse using pliers or special tweezers;
4. insert a new fuse rated for the same current;
5. close the lid.

Purpose of VAZ 2107 fuses

The essence of the operation of fuses is that when the current passing through them exceeds, the insert located inside burns out, thereby preventing heating, melting and fire of the wiring. If an element has become unusable, it must be found and replaced with a new one. How to do this and in what sequence you need to understand in more detail.

Various fuses were installed on the VAZ 2107, but they have one purpose - to protect electrical circuits
