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.
Turn battery disconnect switch to OFF position (WP 0007). Remove clevis pin from
base casting and linear actuator from non-operating equipment ladder rack. Slowly
bring channel support down to farthest possible position. Disconnect driver side body
wire harness equipment ladder rack motor connector. Turn battery disconnect switch to
ON position (WP 0007). While an assistant holds POWERED EQUIPMENT RACK
LIFT switch to DOWN position (WP 0011), check for 22 to 28 VDC between driver side
body wire harness wire 2828 (red) at driver side body wire harness equipment ladder
rack connector, terminal B and a known good ground.
If 22 to 28 are not present, repair wire 2828 in driver side body wire harness
if repairable (TM 9-2320-325-14&P), or replace driver side body wire
harness (WP 0448).
