Checking the Power Supply For Shorting

Testing Methods: Checking The Power Supply For Shorting:




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 along to the circuit's grounding point.
4. If the voltmeter shows a reading, it indicates that voltage is present at the point concerned.
