The relay – the general information and check of serviceability of functioning

General information

For giving of power supply or a signal of management on many of consumers of the electric power in the car (such as components of system of injection of fuel, a horn, a starter, the cooling system fan(s), fog lights and so forth) relays are used. Actually, the relay represents the electric key providing short circuit of VV of a contour on NV to a signal. In case of a relay exit out of operation there is a refusal of functioning of the corresponding consumer. The most part of the relay is located in a motive compartment, others "are scattered" on the car. The description of check of serviceability of functioning of the relay is given below. The failed relays are subject to replacement.

Check

Correctness of connection of the relay can always be defined on provided in the Section of the Scheme of electric connections – the general information to schemes of electric connections.

Usually the contour of management is always connected to two of contact plugs of the relay. When giving on these NV plugs of tension current begins to circulate on a winding of management of the relay therefore there is a short circuit of big contacts of a working contour of the consumer of the electric power. Other plugs are plugs of working (VV) of a contour and become isolated among themselves when giving food on a contour of management.

For the purpose of simplification of identification of plugs of the relay explanatory marking with the image of the scheme of connection of keys is usually applied on its case. If similar marking is absent, it is necessary to address schemes of electric connections (see the Section of the Scheme of electric connections – the general information).

 PERFORMANCE ORDER

1. For check connect an ohmmeter between two VV plugs of a contour of the relay, in the relay of normally opened type conductivity has to be absent. Now connect the wire crossing point equipped with a safety lock between one of plugs of management of the relay and the positive plug of the battery (In +). By means of other wire crossing point ground the second plug of management, the relay has to publish click after which the ohmmeter will record conductivity existence (the relay of normally opened type). Some relays demand obligatory respect for polarity of connection.
2. At negative result of check replace the relay.
