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 wire continuity to determine if hidden breaks exist.

Use electrical schematic to trace path of wire (WP 0326 00).

Connect ohmmeter leads to each end of wire.

An infinite resistance reading indicates a broken wire.
