Relay

Relay - is an electronically-controlled switch, which is normally used as follows:

- Remote switches large currents from the circuit in which the current flows, this allowing the use of thinner wires and contacts of switches;

- It has more than one control input, unlike a mechanical switch;

- Performs the function of a timer, for example, sets the interval wiper.

If the electrical circuit controlled by a relay fails and the cause of the fault is probably relay, listen to the relay when the system. If the relay is working correctly, you should hear a click when it is turned on. If the relay is serviceable, the cause of the problem lies in the elements, or connecting wires. If the relay does not work, it means that it does not receive the main power or control pulse or relay is faulty.

Most of the relay is set in the fuse and relay located in the engine compartment.

Some specialized relays are located separately or in separate units under the instrument panel and the engine compartment.
