Strategy For Locating Faults

If the value of a ground or power circuit is out of range or a signal is suspected as being faulty, then use the following methods to determine the fault.

- Inspect circuit wires for visible breaks or shorts, loose connectors, bent or pushed out connector pins, or corrosion.

- Test battery for low voltage and current.

- Perform Monitor Wiggle Test on the problem circuit. An audible beep will sound if an intermittent short or open is present.

- Perform click testing for those signals which activate relays or solenoids. Using the switch box in the selector pin jacks allows relays and solenoids to be activated.

- If no faults found, proceed with Power and Ground tests. Power and Ground Tests
