Electrical Troubleshooting Tools: Ohmmeter

WARNING: This page is about a different car, the 2005 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Do not connect the ohmmeter to any circuit where voltage is applied. This will damage the ohmmeter.

The ohmmeter is used to measure the resistance between two points in a circuit and to inspect for continuity and short circuits.
