VOLTAGE TEST
(1) Disconnect AC harness AC condenser assembly
connector (WP 0028).
(2) Turn engine start switch ON (TM 9-2320-364-10).
(3) Place positive (+) probe of multimeter on AC
harness wire 1155 at AC condenser assembly
connector, terminal A.
(4) Place negative (-) probe of multimeter on a known
good ground.
(a) If 22 to 28 vdc are not measured, turn engine
start switch OFF and repair AC harness wire
1155 (see Appendix A) or replace AC wiring
harness (WP 0048). Verify repair, go to Step 15
of this fault.
(b) If 22 to 28 vdc are measured, go to Step 7 of
this fault.
VOLTAGE TEST
(1) Turn fan control switch to an on position (low,
medium, or high) (WP 0004).
(2) Turn temperature control switch to the coldest
position (fully clockwise) (WP 0004).
(3) If OFF, turn engine start switch ON
(TM 9-2320-364-10).
(4) Place positive (+) probe of multimeter on AC
harness wire 1156 at AC condenser assembly
connector, terminal B.
(5) Place negative (-) probe of multimeter on a known
good ground.
(a) If 22 to 28 vdc are not measured, turn engine
start switch OFF and repair AC harness wire
1156 (see Appendix A) or replace AC wiring
harness (WP 0048). Verify repair, go to Step 15
of this fault.
