Fuses in a car protect most circuits. The fuse rating is calculated taking into account the load of the electrical circuit.

If you install a fuse of a larger rating, then at significant loads the circuit elements (wiring and details of the electrical circuit diagram) will fail

If you install a fuse of a lower rating than it is calculated according to the scheme, then the fuse will fail even with insignificant loads. Therefore, it is necessary to install fuses of the appropriate rating.

Consumers with high power are connected via a relay

Carry out any work on the car's electrical equipment only with the battery disconnected.

Disconnect or connect the battery only with the ignition off.

When checking the circuits of electrical equipment, it is forbidden to short-circuit the wires to ground (check the serviceability of the circuits "for a spark"), as this can lead to failure of the electrical components.

It is forbidden to use fuses that are not provided for by the design of the car or designed for a higher current, as well as use wire instead of fuses.

When replacing fuses, do not use screwdrivers, as this can lead to a short circuit in the electrical circuits.

It is forbidden to disconnect the battery while the engine is running in order to avoid damage to the voltage regulator and electronic components of the car.

When carrying out electric welding work on a car, it is necessary to disconnect the wires from the terminals of the battery, generator and the electronic engine control unit.

The fuse boxes are located under the hood and in the passenger compartment.

To access the mounting block in the car, pry the recess in the decorative cover of the mounting block with your fingers

Remove the cover from the instrument panel

On the inside of the decorative cover there is a fuse diagram

Before replacing a blown fuse, you need to find out the cause of the blown out and eliminate the cause.

We look at the table which circuit this fuse protects, check this circuit, eliminate the malfunction, and only then install a new fuse of the same rating.

The fuse box in the passenger compartment is located in the dashboard on the left side under a decorative cover

The purpose of the fuses is indicated on the block and in the figure.

The troubleshooting circle is usually narrowed by the gradual identification and elimination of normally functioning elements of the same circuit.

If several elements or circuits fail at the same time, the most likely cause of failure is a blown fuse or failure of contact with "ground" (different circuits in many cases can be closed to one fuse or ground terminal).

Failures of electrical equipment are often explained by the simplest reasons, such as corrosion of connector contacts, fuse failure, blown fuse or relay damage.

Visually check the condition of all fuses, wiring and connectors on the circuit before proceeding with a more detailed check of the health of its components.

One method for finding a short circuit is to remove the fuse and connect a probe lamp or voltmeter instead.

There must be no voltage in the circuit. Tug the wiring while observing the probe lamp.

If the lamp starts blinking, there is a short to ground somewhere in this wiring harness, possibly caused by frayed wire insulation.

A similar check can be carried out for each of the components of the electrical circuit by closing the corresponding switches.

It should be borne in mind that, depending on the configuration, fuses may be added, or fuses may not be present.

Under the hood of the car, the fuse box is located on the left side in the direction of travel of the car and is covered by a cover.
