Lincoln FOAZ-14N089-B Relay

You can Select Your Vehicle to check if FOAZ-14N089-B fits your vehicle.

Many vehicle accessories utilize relays for transmitting electrical signals. To check if the relay is fine, take it out of the car and test for continuity across the power circuit terminals. Place a fused jumper wire between one control circuit terminal and the positive battery terminal and another jumper wire between the other control circuit terminal and ground. Check for continuity across the power circuit terminals. It requires replacement if any of these tests are failed by the relay.

The various relays are mounted in the engine compartment and several locations throughout the vehicle.

If the ohmmeter shows infinite resistance in both directions, the relay should be replaced.

If the relay is defective, the component it controls will not operate properly.

Relays use a low-current circuit (the control circuit) to open and close a high-current circuit (the power circuit).

Relays use a low-current circuit (the control circuit) to open and close a high-current circuit (the power circuit).

The various relays are mounted in the engine compartment and in several locations throughout the vehicle.

Terminal 30 is normally connected to the battery voltage (B+) source for the circuit loads.

If a faulty relay is suspected, it can be removed and tested using the provided procedure or by a dealer service department or other repair shop. Defective relays must be replaced as a unit.

Relays use a low-current circuit (the control circuit) to open and close a high-current circuit (the power circuit).

To test for continuity between the relay power circuit terminals, remove the relay from the vehicle and use an ohmmeter. There should be no continuity between terminal 30 and 87 with the relay de-energized.
