Testing For Open Circuits By Measuring Resistance

WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

  1. Make sure the component or lead to be tested is not under tension (e.g. by removing the relevant fuse).
  2. Set the multimeter for measuring ohms and connect the ohmmeter to each end of the component/lead to be tested.
  3. Jiggle the relevant wiring harness while observing the ohmmeter.

    Normally, the resistance of a wiring harness is less than 1 ohm. Specified values apply to components.
