The vehicle's on-board circuit (except the starter circuit) is powered through two fuses

The lighting circuit is protected by a 40 A fuse, the remaining circuits are 60 A.

Both fuses are installed in a block mounted on the partition in the engine compartment

In addition, each circuit of all electricity consumers is additionally protected by fuses with a lower operating current.

They are located in two blocks under the instrument panel on the driver's side.

The rated current of the fuses and the circuits they protect are indicated in the table.

Fuses are numbered from left to right, 8 A - black; 16 A – green.

The starter circuit is designed for short-term high current and does not have a fuse.

When repairing the electrical system, disconnect the battery. Do not use oversized fuses or homemade fuses - this can lead to failure of the electrical consumer and possibly a fire.

Fuses GAZ-2705

Use your fingers, squeezing the latches on both sides, and remove the unit cover.

Fuses GAZ-2705

Using a 10mm wrench, unscrew the two nuts and, removing the wires from the studs, replace the faulty fuse with a similar one (40 A or 60 A).

Replacing fuses for electrical circuits

Fuses GAZ-2705

Remove the block cover.

Fuses GAZ-2705

Fuses are installed between spring terminals.

8 A fuses have a black insulator, 16 A fuses have a green insulator.

They are arranged in numerical order from left to right.

For cars manufactured since 2003, release the cover latch

Fuses GAZ-2705

Remove the cover

Having pressed the lower or upper terminal, remove the faulty fuse and install a new one.
