    Q:
    How to test and replace a faulty relay in a Lincoln Mark VII? Posted by Skip D.
    A:
    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.
