    Q:
    How are the terminals on most relays configured for the 2003 Ford Crown Victoria? Posted by Customer
    A:
    On most relays, two of the terminals are the relay's control circuit (they connect to the relay coil which, when energized, closes the large contacts to complete the circuit). The other terminals are the power circuit (they are connected together within the relay when the control-circuit coil is energized).

    Q:
    What should you do if the relay doesn't click during the test for the 1995 Lincoln Town Car? Posted by Customer
    A:
    If the relay doesn't click during the test, you may try swapping the jumper wires on the control circuit terminals, as polarity can be critical on some relays. If it still doesn't click, it's likely defective and should be replaced.
