3. On the ECT sensor when the temperature reaches
20° C (68° F), the meter should read approxi-
mately 2.45k ohms.
4. On the ECT sensor when the temperature reaches
50° C (122° F), the meter should read approxi-
mately 800 ohms.
5. On the ECT sensor when the temperature reaches
80° C (176° F), the meter should read approxi-
mately 318 ohms.
6. On the ECT sensor when the temperature reaches
110° C (230° F), the meter should read approxi-
mately 142 ohms.
7. If the readings are not as indicated, the sensor
must be replaced.
8. Install the sensor and tighten securely.
9. Connect the leads.
Fan Motor
The connector is the black two-prong one located
above the oil cooler/radiator.
NOTE: The ignition switch must be in the ON
position.
RESISTANCE
(Fan Motor Connector)
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to the blue wire; then
connect the black tester lead to the black wire.
FI501A
3. The meter must show less than 1 ohm.
NOTE: If the meter shows more than 1 ohm of
resistance, troubleshoot or replace the fan motor.
NOTE: To determine if the fan motor is good,
connect the red wire from the fan connector to the
positive side of a 12 volt battery; then connect the
black wire from the fan connector to the negative
side. The fan should operate.
Power Distribution
Module (PDM)
The fuses are located in a power distribution module
under the seat. If there is any type of electrical system
failure, always check the fuses first.
NOTE: The ignition switch must be in the LIGHTS
position.
1. Remove all fuses from the distribution module.
2. Set the meter selector to the DC Voltage position.
3. Connect the black tester lead to ground.
4. Using the red tester lead, contact each end of the
fuse holder connector terminals individually.
5. The meter must show battery voltage from one
side of the connector terminal ends.
NOTE: Battery voltage will be indicated from only
one side of the fuse holder connector terminal; the
other side will show no voltage.
NOTE: When testing the HI fuse holder, the head-
light dimmer switch must be in the HI position;
when testing the LIGHTS fuse holder, the headlight
dimmer switch can be in either position.
NOTE: If the meter shows no battery voltage,
troubleshoot the battery, switches, distribution
module, or the main wiring harness.
FUSES
NOTE: To remove a fuse, compress the locking
tabs on either side of the fuse case and lift out.
