WARN I N G
Jewelry can catch on equipment and cause injury or short across electrical circuit and cause severe
burns or electrical shock. Remove rings, bracelets, watches, necklaces, and any other jewelry
before working around HET Tractor.
VOLTAGE TEST
(1) Disconnect A/C compressor receiver/
dryer harness connector from A/C
engine fan control solenoid.
(2) Connect jumper wire across A/C
compressor receiver/dryer harness A/C
high pressure switch connector
terminals.
(3) Turn engine switch to ON position
(TM 9-2320-360-10).
(4) Place positive (+) probe of multimeter
on yellow wire at A/C compressor
receiver/dryer harness A/C engine fan
control solenoid connector.
(5) Place negative (-) probe of multimeter
on ground.
(a) If 12 to 14 vdc is not measured,
turn engine switch to OFF position
and go to Step 6 of this fault.
(b) If 12 to 14 vdc is measured, turn
engine switch to OFF position and
go to Step 5 of this fault.
CONTINUITY TEST
(1) Set multimeter switch to ohms.
(2) Is there continuity measured on black
wire from A/C compressor receiver/
dryer harness A/C engine fan control
solenoid connector to ground.
(a) If continuity is not measured, repair
black wire from A/C engine fan
control solenoid connector to A/C
evaporator harness connector
(See WP 0057 00, Fig j) or notify
DS Maintenance. Verify repair, go
to Step 10 of this fault.
(b) If continuity is measured, replace
A/C engine fan control solenoid
(WP 0026 00). Verify repair, go to
Step 10 of this fault.
