TEST OR INSPECTION
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.
Release cab TANK TO PUMP switch (WP 0004). Turn battery disconnect switch to
OFF position (WP 0007). Open pump operator's panel housing (WP 0325). While an
assistant puts pump operator's panel TANK TO PUMP switch to closed
position (WP 0004), check for continuity across pump operator's panel TANK TO PUMP
switch, from terminal wire 2854 (red) to terminal wire 2770 (blue).
If there is no continuity, replace pump operator's panel TANK TO PUMP
switch (WP 0338).
