Most electrical circuits are protected by fuses. The electric motors of the gear motors (windshield wipers, rear door glass, headlights - if installed) are protected by automatic bimetallic fuses of multiple action. The power supply circuit of the injection system (vAZ-21214 engine) protected by a fuse made of a wire with a core of reduced cross-section (1 mm²). The battery charging circuit, ignition circuit are not protected (vAZ-21213 engine), engine start, the circuit "generator - ignition switch - fuse box". Powerful consumers (starter, headlights, electric motors of cooling system fans, electric fuel pump, etc.) are connected via a relay.
The fuses are grouped in two fuse boxes located on the left under the instrument panel. The fuse ratings and the circuits they protect are shown in the table.
Injection system fuses (vAZ-21214 engine) are located in a separate block on the left side panel under the instrument panel.
A 30 A fuse protects the power supply circuit of the radiator electric fans, and three 15 A fuses protect the electric fuel pump and control unit, respectively (DC power input) and the main relay circuit of the injection system (see also Injection engine control system).
Caution! When repairing the electrical system, disconnect the negative terminal of the battery (with the engine off).
Before installing a new fuse to replace a blown one, find out and fix the cause of the blown fuse.
Do not use fuses of increased rating or homemade ones - this may cause a fire
Due to the risk of short circuit, do not pry off blown fuses with metal tools (with screwdrivers), if the relevant circuits are not de-energized.
