Step 6.
Turn battery disconnect switch to OFF position (WP 0007).
Reconnect cab discharge
digital pressure gauge wire harness connector to PUMP DISCHARGE digital pressure
gauge.
Disconnect pump intake pressure transducer wire harness connector from
pump intake pressure transducer.
With a test lead set, check for continuity across
sensor signal wire from pump intake digital pressure gauge wire harness connector,
terminal 2, to pump intake pressure transducer wire harness connector, terminal C.
If continuity is not present, repair sensor signal wire in pump intake pressure
transducer wire harness if repairable (TM 9-2320-325-14&P), or replace
pump intake pressure transducer wire harness (WP 0460).
Step 7.
With a test lead set, check for continuity across sensor ground wire from pump intake
digital pressure gauge wire harness connector, terminal 6, to pump intake pressure
transducer wire harness connector, terminal A.
If continuity is not present, repair sensor ground wire in pump intake
pressure transducer wire harness if repairable (TM 9-2320-325-14&P), or
replace pump intake pressure transducer wire harness (WP 0460).
Step 8.
With a test lead set, check for continuity across sensor power wire from pump intake
digital pressure gauge wire harness connector, terminal 3, to pump intake pressure
transducer wire harness connector, terminal B.
If continuity is not present, repair sensor ground wire in pump intake
pressure transducer wire harness if repairable (TM 9-2320-325-14&P), or
replace pump intake pressure transducer wire harness (WP 0460).
