 TM 9-2320-364-34-1
Remove all jewelry such as rings, dog tags, bracelets, etc. If jewelry or tools contact positive electrical circuits, a
direct short may result. Damage to equipment, injury or death to personnel may occur.
NOTE
Arctic heater temperature sensor resistance is between 650 ohms at -13_F (-25_C) and 1000 ohms at 77_F (25_C).
CONTINUITY TEST
(1) Ensure engine coolant temperature
is between -13_ and 77_F (-25_
and 25_C).
(2) Remove cover from arctic heater
(TM 9-2320-364-20).
(3) Disconnect arctic heater unit harness
connector from arctic heater control unit
(TM 9-2320-364-20).
(4) Remove three screws and arctic heater
control unit (Para 18-2.2).
(5) Connect positive (+) lead to yellow wire
at arctic heater internal harness
connector, terminal 14.
(6) Connect negative (-) lead to yellow wire
at arctic heater internal terminal 18.
(7) Is resistance measured across arctic
heater temperature sensor between 650
and 1000 ohms at room temperature?
(a) If resistance reading is not between
650 and 1000 ohms at room
temperature, replace arctic heater
temperature sensor (Para 18-2.2).
(b) If resistance reading is between 650
and 1000 ohms at room temperature,
go to Step 2 of this Fault.
