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 valve control
wire harness connectors from TANK FILL & RE-CIRCULATING LINE valve control and
tank fill & re-circulating line valve motor. With a test lead set, check for continuity
between valve motor valve control wire harness and TANK FILL & RE-CIRCULATING
LINE valve control connectors terminal to terminal.
If there is no continuity, repair wires (TM 9-2320-325-14&P), or replace tank
fill & re-circulating line valve control wire harness (WP 0453).
