TEST OR INSPECTION
Remove rings, wristwatches, neck chains, and any other jewelry before working
around vehicle. Jewelry can catch on equipment and cause serious injury. Jewelry
and tools may short across electrical circuits and cause damage to equipment, or
severe burns or electrical shock to personnel.
Disconnect main wire harness driver side body wire harness connector. With a test
lead set, check for continuity across main wire harness wire 2640 (black) from driver
side body wire harness connector, terminal 10 to a known good ground.
If there is continuity, repair wire 2640 in driver side body wire harness if
repairable (TM 9-2320-325-14&P), or replace driver side body wire
harness (WP 0448).
If there is no continuity at either terminal, repair wire 2640 in main wire
harness if repairable (TM 9-2320-325-14&P), or replace main wire
harness (WP 0455).
