Power and Ground Tests
*** UPDATED BY TSB# 91-14-B1 DATED 08-30-93Strategy for locating power and ground 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.
1. Perform monitor wiggle testing on the problem circuit. An audible beep will sound if an intermittent short or open is present.
2. 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.
3. If no faults found, PROCEED with Power and Ground tests.
