Checking For Short-Circuit to Power Supply

Checking For Short-Circuit To Power Supply:

1 Disconnect the fuse from the system to be checked.
2 Connect one of the voltmeter's leads to B+.
3 Connect the other voltmeter lead to the point in the circuit to be checked.
Take a reading on the load side of the wiring harness and work outwards to the circuit's grounding point.
4 If the voltmeter shows a reading, it indicates that voltage is present at the point concerned.
