Repair and operation of the car

Check of the relay

Relays are built in many current contours. The switching relay works as the switch. For example: When driving beam is turned on via the manual switch, the relay receives the command, a tax for lamps of driving beam current. It is possible to give, of course, current from the battery on lamps directly via the manual switch. At all consumers of the electric power with a high current (high beam headlamps, screen wipers, fog lights) relays are switched on not to overload the switch and to provide the shortest way for current. Along with such switching relays there are also functional relays, for example for system of windscreen washer screen wiper or the relay of a signal of inclusion of external lighting.

Check of switching relays

At inclusion of the corresponding consumer on the relay the signal of management is given, it means, the magnetic coil in the relay pulls contact and closes a contour of "working current". Working current proceeds via the relay further to the consumer.

It is the simplest to check serviceability of the relay, having replaced it with obviously serviceable. Act in workshops this way. As fans very seldom have on hand a serviceable spare relay, the following step with the so-called switching relay which except other is used for inclusion of fog and main lights is recommended.
