3. Connect the red tester lead to the white/green wire on
the harness side of the connector.
4. Turn the ignition switch to the RUN position.
5. The meter must show battery voltage.
NOTE: If the meter shows other than specified,
check the harness, connector, main relay, and battery
connections.
RESISTANCE (Gear Position)
The gear position switch is located on the engine/trans-
mission next to the shift arm.
FI525B
1. Disconnect the gear position switch connector; then
using a multimeter, test the switch in each position as
follows. Resistance must be less than 1 ohm for all
tests.
KC410A
A. Neutral (N)Pins 3 to 4
B. Reverse (R)Pins 3 to 4 and 3 to 2
C. High (H)Pins 3 to 4 and 3 to 1
D. Low (L)Pins 3 to 1
2. Connect the harness to the gear position switch.
Fan Motor
NOTE: To determine if the fan motor is good, con-
nect the blue wire from the fan connector to the posi-
tive side of a 12 volt DC power supply; then connect
the black wire from the fan connector to the negative
side. The fan should operate.
KC270A
NOTE: Fan motor resistance checks are not recom-
mended. Resistance values change with the motor
commutator position.
Front Drive Actuator
NOTE: With the engine stopped and the ignition
switch in the ON position, a momentary “whirring”
sound must be noticeable each time the select switch is
moved to 2WD and 4WD. Test the switch, main relay,
and wiring connections prior to testing the actuator.
VOLTAGE
1. Select the 2WD position on the drive select switch;
then disconnect the connector on the actuator wiring
harness.
2. With the ignition switch in the OFF position, connect
the black tester lead to the black wire in the supply
harness; then connect the red tester lead to either
orange wire in the supply harness.
3. Turn the ignition switch to the ON position. The
meter must show battery voltage.
4. Connect the red tester lead to the second orange wire
in the supply harness. The meter must show battery
voltage.
5. Connect the red tester lead to the white/green wire in
the supply harness. The meter must show battery
voltage.
This component can be tested using the CATT II. Utilize
the Test screen.
! WARNING
Care should be taken to keep clear of the fan blades.
