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 ON position (WP 0007). Check for 22 to 28 VDC
between wire 2834 (red) at FOAM FLUSH switch, terminal to a known good ground.
If 22 to 28 VDC are not present, repair wire 2834 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).
If 22 to 28 VDC are present, replace FOAM FLUSH switch (WP 0338).
