Circuit breakers
The main fuses, relays and timers are located in the central electrical box located under the dashboard on the driver's side. Additional fuses are located in the box in front of the battery (see fig. 12.1). The fuses can be inspected and, if necessary, replaced by opening the box cover. The location of the fuses and relays is shown on the cover of the box. Each fuse has an inscription about the amount of passed current.
In order to shine the fuse, use the tweezers located on the cover to remove the fuse from the socket. Remove the fuse from the tweezers The wire inside the fuse is easily visible and will be broken if the fuse is blown (see fig. 12.2).
Always replace the fuse with another fuse of the same rating. Never replace a fuse more than once without determining the cause of the blown fuse. The power of the fuse is given on the cover of the box.
Relay
A relay is an electronically controlled switch that is typically used in the following way:
- the relay can switch high voltage current remotely from the circuit in which this current flows, allowing the use of thinner wires and switch contacts;
- a relay can have more than one control input, unlike a mechanical switch;
- the relay can act as a timer. for example, set the wiper interval.
Relays are located on the back of the fuse box Various relays can be removed by gently pulling them out of their sockets (see fig. 12.3).
If a relay-controlled system fails, and the cause of the failure is probably the relay, listen for the operation of the relay while the system is on. If the relay is functioning properly, you should hear a click when it turns on. If the relay is OK, then the cause of the malfunction lies in the elements or connecting wires. If the relay does not function, it means that it does not receive the main power supply or control pulse, or the relay is faulty.
