set, check for 22 to 28 VDC at wire 2341 from pump operator's panel cab discharge
digital pressure gauge wire harness pump discharge digital pressure gauge wire
harness connector, terminal 4 to a known good ground.
If 22 to 28 VDC are not present, replace cab discharge digital pressure
gauge wire harness (WP 0438).
Step 34.
