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.
With a test lead set, check for continuity across main wire harness wire 1640 from main
wire harness personnel cab pressure governor 4-terminal connector, terminal 2 to a
known good ground.
If continuity is present, replace personnel cab governor control
panel (WP 0309).
If continuity is not present, repair wire 1640 in main wire harness if
repairable (TM 9-2320-325-14&P), or replace main wire
harness (WP 0455).
