  1. Make sure the lead being tested is not under tension (e.g. remove the relevant fuse) and that any loads are disconnected.
  2. Set the multimeter for measuring ohms.
  3. Connect one test lead to a good ground and the other to the point to be tested.
  4. Carefully jiggle the wiring harness and make sure the multimeter reading shows infinite resistance (OL) all the time.
