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 NO. 1 DRIVER SIDE DISCHARGE valve control.
Disconnect valve control wire harness connector from No. 1 driver side discharge valve
motor. With a test lead set, check for continuity across discharge valve control wire
harness from terminal to terminal.
If there is no continuity, repair discharge valve control wire harness if
repairable (TM 9-2320-325-14&P), or replace No. 1 driver side discharge
valve control wire harness (WP 0453).
