TESTING

NOTE

Failure of an electrical device to function is more likely due to a faulty switch (actuator) or to a faulty device

itself, than to a broken wire in wiring harness. Do not assume that a broken wire exists until related electrical

device and actuator have been checked.

Inspect wires for poor connections at terminals, cuts or other defects.

Check continuity of suspected wires to determine if hidden breaks exist.

Use electrical schematic to locate both terminals of suspected wire.

NOTE

A zero reading indicates a broken wire.

Connect ohmmeter leads to each end of wire.

Disconnect suspected wire and an adjacent wire. At one end of wires, connect the two wire terminals together. At the

other end of the wires, connect ohmmeter leads to terminals of these two wires at other ends.
