ICON 3
Remove rings, wristwatches, neck chains, and any other jewelry before working
around vehicle. Jewelry can catch on equipment and cause serious injury. Jewelry
and tools may short across electrical circuits and cause damage to equipment, or
severe burns or electrical shock to personnel.
NOTE
Sensor failure or problems may occur due to moisture and corrosion. Inspect pressure
transducer and connector for damaged terminals, loose water seal wedge lock
connections, moisture, corrosion, and other foreign objects, using a bright light.
Step 8.
Turn water pump engine off (WP 0022). Open pump operator's panel
housing (WP 0325). Remove cab instrument panel E (WP 0311). Turn battery
disconnect switch to OFF position (WP 0007). Disconnect main wire harness
personnel cab pressure governor control 12-terminal wire harness connector.
Disconnect personnel cab pressure governor pressure transducer wire harness
connector. With a test lead set, check for continuity across red wire from pressure
transducer connector, terminal 1 to pressure governor 12-terminal connector,
terminal 6.
If continuity is not present, replace pressure transducer wire
harness (WP 0460).
Step 9.
With a test lead set, check for continuity across white wire from pressure transducer
connector, terminal 3 to pressure governor 12-terminal connector, terminal 7.
If continuity is not present, replace pressure transducer wire
harness (WP 0460).
Step 10.
With a test lead set, check for continuity across black wire from pressure transducer
connector, terminal 2 to pressure governor 12-terminal connector, terminal 5.
If continuity is not present, replace pressure transducer wire
harness (WP 0460).
