If a faulty relay is suspected, it can be unbolted and checked in accordance with this procedure, or taken to a dealer service department or auto repair shop; bad relays must be replaced as a single unit. In fact, before testing a relay, it is advisable to refer to the wiring diagram of the circuit to know the correct connections. Normally, two of them are terminals of the control circuit allowing for connection to the relay coil and two other are power circuit terminals which make internal connection when the control circuit coil is energized. The most relays are labeled to make identification of the control and power circuits possible. To test, simply disconnect the relay and can check for continuity between the power circuit terminals, there must be no connection between the terminal 30 and 87. Then connect a fused jumper wire from one of the control circuit terminal to the positive lead of the battery and another fused jumper wire from the second terminal of the control circuit to the negative terminal; the relay should click when connected. Otherwise, it may just 'not click' and then the jumper wires may need to be flipped around. Then probe and connect the jumper wires, and test if there is continuity between the power circuit terminals, between 30 and 87, there should be continuity in this one. In the case of failure of any of these tests, then the relay should be replaced.
