Relay check

Relays are built in many those contours. The switching relay works as the switch. For example: When the driving beam joins via the manual switch, the relay receives command, a tax for lamps of a driving beam a current. It is possible to submit, of course, a current from the battery on lamps directly via the manual switch. At all consumers of the electric power with a high current (headlights of a driving beam, screen wipers, fog lights) are included the relay not to overload the switch and to provide for a current the shortest way. Along with such switching relays there are also functional relays, for example for system of a stekloomyvatelya-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 management signal is given, it means, the magnetic coil in the relay pulls contact and closes a contour of "a working current". The working current proceeds via the relay further to the consumer.

It is simplest to check serviceability of the relay, having replaced it with the obviously serviceable. So arrive in workshops. 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.


    To take out the relay from fastening. To include ignition and the corresponding switch. At first by the indicator of tension to determine, whether tension is put to the corresponding plusovy plug of a nest of the relay. For this purpose to connect the indicator to weight and other contact carefully to insert into the plug. If the light-emitting diode of the indicator lights up, tension is put. If the indicator showed lack of tension, to check conducting on break existence from a plusovy pole of the battery to the plug according to the scheme. To make a crossing point of a piece of the isolated wire, the ends should be smoothed out. To connect this crossing point in a relay nest the plug of plus of the battery which carries constantly out tension with a relay exit. It almost too most what to insert the serviceable relay. In a nest of the relay it is possible to determine an arrangement of plugs by flowers of cables according to the scheme. If at the inserted crossing point the driving beam, for example, lights up, means the relay is faulty. If the driving beam does not light up, to define, whether connection of a headlight with weight is serviceable. Then to check on break a wire from the relay plug to a headlight on the basis of the scheme. If it is required, to insert the new relay.
