Testing Low-Oil

Light Sensor

The low-oil light sensor is a magnetic switch. Its oper-

ation is based on a magnet located around the inside

diameter of a 1/2-in. hole in a plastic float. The switch

located in the stem of the sending unit is positioned

through the hole in the float. When the float drops to

the lower part of the stem, the magnet closes the elec-

trical contacts (located in the stem) allowing the cur-

rent to pass on to the warning light.

If the sensor should fail, it must be replaced. To test

the sensor, use the following procedure.

1. Remove the sensor from the oil reservoir by twist-

ing and pulling upwards. Wipe excess oil from the

sensor.

2. Unplug the sensor from the wiring harness.

3. Set the meter selector to the OHMS position.

4. Touch each of the meter leads to one of the two

wires coming from the sensor. With the sensor in

its normal position (float end down), the meter

should read resistance.

5. If the meter reads no resistance, check to make

sure good contact has been made with each of the

wires coming from the sensor. If the meter still

reads no resistance, replace the sensor.

6. While maintaining contact between the meter

leads and the sensor, raise the float. The meter

must read no resistance. If the meter reads resis-

tance, replace the sensor.

7. If the sensor tested out satisfactory but the light

doesn’t illuminate with only a small amount of oil

in the reservoir, check the bulb.

8. If the bulb is in good condition, check for voltage

at the connection where the sensor plugs into the

accessory wiring harness. Using a multimeter set

on the 50 ACV scale, start the engine and allow it

to idle. Touch the red lead of the voltmeter to the

red wire in the two-prong connector. Touch the

black lead to the black wire in the wiring harness.

At idle, the meter should read 5 to 6 volts (AC). If

no voltage is present but the lights on the snowmo-

bile operate normally, either check the wiring har-

ness for a broken wire or replace the harness.

Testing High

Temperature Sensor

1. Disconnect the main wiring harness connector

from the temperature sensor.

5-20

2. Connect an ohmmeter between the sensor terminal

and any convenient chassis ground (or any brown

wire). The ohmmeter must read less than 20 ohms

of resistance with the water temperature more than

+230°F. The ohmmeter must read no resistance

with the water temperature less than +190°F.

NOTE: If the sensor has been removed from the
engine for testing purposes, immerse the sensor
body (only up to the threads) in automatic trans-
mission fluid and slowly heat the fluid. The ohm-
meter must indicate the above resistances when
connected between the sensor terminal and the
sensor body/chassis.

Testing

High Temperature

Warning Light

NOTE: Prior to testing the warning light, verify
that there is a 10-13V DC power supply from the
white/blue wire at the main/console connector and
to the plug-in at the gauge.

1. Remove the torx-head cap screws securing the

console to the steering support; then move the con-

sole out of the way.

2. Temporarily insert a jumper wire to the white/blue

wire from the console wiring harness connector at

the gauge to any convenient chassis ground (or

any brown wire).

3. If the high temperature warning light is not illumi-

nated with the engine running (and the harness ter-

minal grounded), test the light bulb. An ohmmeter

must read less than 10 ohms across the bulb fila-

ment.

4. If the bulb does not illuminate even when tested

good, use the ohmmeter to test the bulb harness.

Also test the red/white wire continuity from the

temperature sensor connector to the bulb connector.

Testing Fuel Gauge

1. Remove the torx-head cap screws securing the

console to the steering support; then move the con-

sole out of the way.

2. With the meter selector set to the DC Volt position,

connect the red meter lead to the gray wire of the

connector plug-in (at the gauge); then connect the

black meter lead to a chassis ground.

3. With the rear of the snowmobile on a shielded

safety stand, run the engine at 2000 RPM.

4. Meter reading must be within 10-15V DC at the

gauge.

Testing Fuel

Gauge Sender

1. On the F-Series/T-Series, remove the torx-head

cap screws securing the console to the steering

support; then move the console out of the way.

2. On the Crossfire/M-Series, remove the close-out

panel.

3. Disconnect the fuel gauge sender unit from the

main wiring harness.

NOTE: On the Crossfire/M-Series, test from the
black/red two-wire connector. On the F-Series, test
from the two gray wires in the four-wire connector.

4. Connect the ohmmeter leads to the two sender

wires.

5. Compare the reading to the chart following.

Testing

Electric Fuel Pump

1. Remove the torx-head cap screws securing the

console to the steering support; then move the con-

sole out of the way.

2. Disconnect the fuel pump sender four-wire con-

nector from the main wiring harness.

3. Connect the positive lead of a 12-volt power sup-

ply to the red wire and the negative lead of the 12-

volt power supply to the black wire.

4. The pump should operate (it would be heard run-

ning).

NOTE: If the fuel pump fails to operate, reverse
the test leads at the fuel pump connector allowing
the meter to run in the opposite direction. This will
verify that nothing has entered and/or obstructed
the pump.
