TEST OR INSPECTION
For Step 51 it will be necessary to check both wires 1364 (white) at POWERED
EQUIPMENT RACK LIFT switch. Both wires carry same amperage but are used in
reversed voltage at switch to allow equipment ladder rack to raise and lower.
Turn battery disconnect switch to OFF position (WP 0007). Remove relay P10
(WP 0402). With a test lead set, check for continuity across wire 1364 (white) from
relay P10, terminal 30 to POWERED EQUIPMENT RACK LIFT switch, connector and
If there is continuity across both wires 1364, go to Step 54.
If there is no continuity across one wire 1364 at POWERED
EQUIPMENT RACK LIFT switch, repair wire 1364 in ladder rack
control wire harness if repairable (TM 9-2320-325-14&P), or replace
ladder rack control wire harness (WP 0449).
If there is no continuity across both wires 1364 at POWERED
EQUIPMENT RACK LIFT switch, go to Step 52.
