The following procedure tests for a short to voltage in a circuit.
|
1.
|
Remove the power feed (i.e. fuse, control module) from the suspect circuit.
|
|
3.
|
Set the rotary dial of the Digital Multimeter (DMM) to the V (DC) position.
|
|
4.
|
Connect the positive lead of the DMM to one end of the circuit to be tested.
|
|
5.
|
Connect the negative lead of the DMM to a good ground.
|
|
6.
|
Turn ON the ignition and operate all accessories.
|
|
7.
|
If the voltage measured is greater than 1 V, there is a short to voltage in the circuit.
