TEST OR INSPECTION
Install circuit breaker 6 (WP 0398). Open pump operator's panel housing (WP 0325).
Turn battery disconnect switch to ON position (WP 0007). Check for 22 to 28 VDC
between pump operator's panel wire harness wire 2346 (red) at PANEL LIGHTS switch
terminal connector, and a known good ground.
If 22 to 28 VDC are not present, go to Step 22.
Turn battery disconnect switch to OFF position (WP 0007). Check for continuity across
PANEL LIGHTS switch from terminal connector to terminal connector, when switch is
put to on position.
If there is continuity, repair wire 1661 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 there is no continuity, replace PANEL LIGHTS switch (WP 0328).
