severe burns or electrical shock to personnel.
Step 39.
Turn battery disconnect switch to OFF position (WP 0007). Open pump operator's
panel (WP 0325). Disconnect cab discharge digital pressure gauge wire harness
connector from pump discharge pressure transducer wire harness connector. Turn
battery disconnect switch to ON position (WP 0007). With a test lead set, check for 22
to 28 VDC on wire 2341 at pump discharge pressure transducer wire harness
connector, terminal 4.
If 22 to 28 VDC are not present, repair wire 2341 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).
Step 40.
Turn battery disconnect switch to OFF position (WP 0007). With a test lead set, check
for continuity across wire 3895 at pump discharge pressure transducer wire harness
connector, terminal 5 to a known good ground.
a.
If continuity is present, replace cab discharge digital pressure gauge
wire harness (WP 0438).
b.
If continuity is not present, repair wire 3895 in pump operator's panel
wire harness if repairable (TM 9-2320-325-14&P), or replace pump
