Testing for a short to ground with a self-powered test light or ohmmeter 1. Remove the open fuse and disconnect the battery and load. 2. Connect one lead of a self-powered test light or ohmmeter to the fuse terminal load side. 3. Connect the other lead to a known good ground. 4. Beginning near the fuse box, wiggle the harness. Continue this process at convention points about six inches apart while watching the test light or ohmmeter. 5. If the self-powered test light blinks or the ohmmeter needle moves, there is a short to ground in the wiring near that point. Testing for aq short to ground with a short finder 1. Remove the open fuse. Leave the battery connected. 2. Connect the short finder between the positive battery terminal and the load side fuse terminal. 3. Close all switch in series with the wire you are troubleshooting. 4. Turn on the short finder. It sends pulses of current to the short. This creates a pulsing magnetic field around the wiring between the fuse box and the short. 5. Beginning at the fuse box, slowly move the short finder meter along the circuit wiring. The meter will show current pulses along the interior trim. As long as the meter is between the fuse and the short, the needle will |
