With a DMM
- Set the rotary dial of the DMM to the ohms position.
- Disconnect the power feed (i.e. fuse, control module) from the suspect circuit.
- Disconnect the load.
- Press the MIN MAX button on the DMM.
- Connect one lead of the DMM to one end of the circuit to be tested.
- Connect the other lead of the DMM to the other end of the circuit.
- If the DMM displays low or no resistance and a tone is heard, the circuit has good continuity.
