In the car, the application of relay includes fuel injection, horn, starter motor and fog lamps since they need relays to switch on the electrical signals to the units. Relays moved with a low current control circuit to switch on and off a higher current power circuit, and when a relay is bad, the relate component will bad. These relays are usually fitted in the engine bay and in many parts of the car. If a faulty relay is considered, it is required to remove it and test which would involve either a procedure together with some specific instructions or one may have to go to a dealer service department or a repair shop; in case of relays which are faulty ,it is expected that relays have to be replaced as a complete set. In general, there are no hookups that can directly be connected to a relay; therefore, to test it is recommended to check the circuit wiring diagram to identify correct connections. In most of the relays, contacts of two terminals are connected to the control circuit-that is they are connected to the coil of the relay while other two terminals are connected to the power circuit. Relays are mostly provided with markings that help in the identification of the control and power circuit terminals. To confirm, join a fused jumper wire from one terminal of a control circuit to the positive battery terminal, and another fused jumper wire between the other terminal of the control circuit and the negative terminal of the battery; there should be a click sound from the relay. If it does not click, then the jumper wires may have to be changed as they may be polarity sensitive. When placing the wires, verify the relay markings so that continuity should be equivalent to the power circuit terminals. If the relay does not meet any of these test results, then it should be change with a new one.
