Testing for short circuits to ground
WARNING: This page is about a different car, the 2003 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
- Make sure the lead being tested is not under tension (e.g. remove the relevant fuse) and that any loads are disconnected.
- Set the multimeter for measuring ohms.
- Connect one test lead to a good ground and the other to the point to be tested.
- Carefully jiggle the wiring harness and make sure the multimeter reading shows infinite resistance (OL) all the time.
