Testing For a Short to Ground






Testing For a Short to Ground

- Remove the fuse and disconnect all items involved with the fuse.

- Connect a test lamp or a voltmeter across the terminals of the fuse.

- Starting at the fuse block, wiggle the wiring harness about six to eight inches apart and watch the voltmeter/test lamp.

- If the voltmeter registers voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.
