3. When the lever is compressed, the meter must show
less than 1 ohm.

NOTE: If the meter shows more than 1 ohm of resis-
tance, replace the switch.
Engine Coolant
Temperature (ECT)
Sensor

NOTE: Preliminary checks may be performed on this
component using the diagnostic mode on the LCD
gauge (see EFI Diagnostic System in this section).
1. Connect the meter leads (selector in OHMS position)
to the sensor terminals.
2. Suspend the sensor and a thermometer in a container
of cooking oil; then heat the oil.

NOTE: Neither the sensor nor the thermometer
should be allowed to touch the bottom of the con-
tainer or inaccurate readings will occur. Use wire
holders to suspend the sensor and thermometer.
3. On the ECT sensor when the temperature reaches
20° C (68° F), the meter should read approximately
2.45k ohms.
4. On the ECT sensor when the temperature reaches
50° C (122° F), the meter should read approximately
800 ohms.
5. On the ECT sensor when the temperature reaches
80° C (176° F), the meter should read approximately
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 posi-
tion.
RESISTANCE (Fan Motor Connector)
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to the blue wire; then con-
nect 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 resis-
tance, troubleshoot or replace the fan motor.

NOTE: To determine if the fan motor is good, con-
nect the red wire from the fan connector to the posi-
tive 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.
! WARNING
Wear insulated gloves and safety glasses. Heated oil can
cause severe burns.
! WARNING
Care should be taken to keep clear of the fan blades.
