Notice: Refer to Test Probe Notice in the Preface section.

1. Remove the power feed (i.e. fuse, control module) from the suspect circuit (3).
2. Disconnect the load (5).
3. Select the Ω position on the Digital Multimeter (8).
4. Connect the positive lead of the Digital Multimeter (1) to one end of the circuit to be tested (4).
5. Connect the negative lead of the Digital Multimeter (1) to a known good ground (7).
6. If the Digital Multimeter (1) does not display infinite resistance, Over Limit (OL) (2), there is a short to ground in the circuit (6).

1. Review the system schematic and locate the fuse that is open.
2. Open the first connector or switch leading from the fuse to each load.
3. Connect a Digital Multimeter across the fuse terminals (be sure that the fuse is powered).

•	When the Digital Multimeter displays voltage the short is in the wiring leading to the first connector or switch.

•	If the Digital Multimeter does not display voltage refer to the next step.

4. Close each connector or switch until the Digital Multimeter displays voltage in order to find which circuit is shorted.
