The following procedure tests for a short to voltage in a circuit.
1.Set the rotary dial of the DMM to the V (DC) position. 2.Connect the positive lead of the DMM to one end of the circuit to be tested. 3.Connect the negative lead of the DMM to a good ground. 4.Turn ON the ignition and operate all accessories. 5.If the voltage measured is greater than 1 volt, there is a short to voltage in the circuit.
