Step 29.
Turn battery disconnect switch to OFF position (WP 0007).
Disconnect cab pump
discharge digital pressure gauge wire harness connector from cab PUMP DISCHARGE
digital pressure gauge.
Disconnect cab discharge digital pressure gauge wire harness
pump operator’s panel pressure transducer wire harness connector. With a test lead
set, check for continuity across sensor signal wire in cab pump discharge digital
pressure gauge wire harness cab connector terminal 2, to cab discharge digital
pressure gauge wire harness pump operator’s panel pressure transducer wire harness
connector, terminal 2.
If continuity is not present, repair sensor signal wire in cab pump discharge
digital pressure gauge wire harness if repairable (TM 9-2320-325-14&P), or
replace cab discharge digital pressure gauge wire harness (WP 0438).
Step 30.
With a test lead set, check for continuity across sensor ground wire in cab pump
discharge digital pressure gauge wire harness cab connector terminal 5, to cab
discharge digital pressure gauge wire harness pump operator’s panel pressure
transducer wire harness connector, terminal 5.
a.
If continuity is present, replace cab PUMP DISCHARGE digital gauge
(WP 0317).
b.
If continuity is not present, repair ground wire in cab pump discharge
digital pressure gauge wire harness if repairable
(TM 9-2320-325-14&P), or replace cab discharge digital pressure
gauge wire harness (WP 0438).
