Step 29.
Put pump operator's panel FOAM FLUSH switch to OFF position (WP 0004). Turn
battery disconnect switch to OFF position (WP 0007). Open pump operator's panel
housing (WP 0325). Turn battery disconnect switch to ON position (WP 0007). With a
test lead set, check for 22 to 28 VDC between pump operator's panel wire harness wire
2834 (red) at PUMP COOLER switch, terminal and a known good ground.
If 22 to 28 VDC are not present, repair wire 2834 in pump operator's panel
