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 cab instrument
panel cab power distribution wire harness connector. With a test lead set, check for
continuity across wire 4037 (orange) from cab instrument panel wire harness connector
terminal 13 to turret control junction box terminal strip.
If there is continuity, repair wire 4037 in cab power distribution wire harness
if repairable (TM 9-2320-325-14&P), or replace cab power distribution wire
harness and block (WP 0441).
