TEST OR INSPECTION
Open pump operator's panel housing (WP 0325). Remove pump primer motor diode
pack from pump operator's panel wire harness pump primer motor diode pack
connector (WP 0419). While an assistant puts pump operator's panel DRIVER MAIN
INLET PRIMER switch to on position (WP 0004), with a test lead set, check for 22 to 28
VDC between pump operator's panel wire harness wire 2788 (blue) at pump primer
motor diode pack connector terminal C, and a known good ground.
If 22 to 28 VDC are not present, go to Step 72.
