Test # 5

CHECKING WIRES FOR SHORTS AND OPENS

Checking wires for shorts and opens

IMPORTANT
Make sure the ignition switch is "off" for the following tests.

Shorts:




^ Set your ohmmeter to ohms times one (Rx1).

^ Connect one lead of your ohmmeter to one end of the suspect wire.

^ Connect the other lead of your ohmmeter to a good ground.

^ If the meter reads ANYTHING other than infinity, you have a short to ground in that wire.

Opens:

^ If a suspect wire has no voltage through it, and its connection at both ends is good, and it's not shorted to ground, the wire has an open in it.

^ Replace the wire.
