Step 16.
Turn battery disconnect switch to OFF position (WP 0007).
Reconnect pump operator’s
panel wire harness PUMP INTAKE digital pressure gauge wire harness connector.
With
a test lead set, check for continuity across sensor power wire, from pump discharge
digital pressure gauge wire harness connector, terminal 3 to cab discharge digital
pressure gauge wire harness pump discharge pressure transducer connector, terminal
3.
If continuity is not present, repair sensor power wire in cab 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 17.
With a test lead set, check for continuity across sensor signal wire from pump discharge
digital pressure gauge wire harness connector, terminal 2, to cab discharge digital
pressure gauge wire harness pump discharge pressure transducer wire harness
connector, terminal 2.
If continuity is not present, repair sensor signal wire in cab 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 18.
With a test lead set, check for continuity across sensor ground wire from pump
discharge digital pressure gauge wire harness connector, terminal 6, to cab discharge
digital pressure gauge wire harness pump discharge pressure transducer wire harness
connector, terminal 6.
a.
If continuity is present, replace pump operator’s panel PUMP DIGITAL
PRESSURE DISCHARGE gauge (WP 0317).
b.
If continuity is not present, repair sensor ground wire in cab 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).
