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.
Connect batteries (WP 0368). Check for 10 to 14 VDC between wire 1663 at cab
power distribution wire harness circuit breaker 4 terminal and a known good ground.
If 10 to 14 VDC are present, repair wire 2074 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).
