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.
Turn battery disconnect switch to OFF position (WP 0007). Disconnect main wire
harness pump operator's panel wire harness connector DO2. Turn battery disconnect
switch to ON position (WP 0007). With a test lead set, check for 22 to 28 VDC between
main wire harness wire 2346 (red) at main wire harness pump operator's panel wire
harness connector DO2, terminal 8 and a known good ground.
If 22 to 28 VDC are present, repair wire 2346 in pump operator's panel wire
harness if repairable (TM 9-2320-325-14&P), or replace pump operator's
panel wire harness (WP 0459).
