Step 25.
Reconnect pump intake digital pressure gauge wire harness connector to PUMP
INTAKE digital pressure gauge (WP 0317).
Disconnect cab discharge digital pressure
gauge wire harness connector (WP 0438).
With a test lead set, check for continuity
across sensor ground wire from pump discharge digital pressure gauge wire harness
connector terminal 2, to cab discharge digital pressure wire harness connector,
terminal 2.
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).
Step 26.
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 wire harness 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 27.
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 wire harness connector, terminal 6.
a.
If continuity is present, replace pump operator’s panel PUMP
DISCHARGE digital pressure 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).
