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

twisting and pulling upwards. Wipe excess oil
from the sensor.

2. Unplug the sensor from the wiring harness.

3. Using an ohmmeter, set the selector on the X1K

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
resistance, 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
snowmobile operate normally, either check the
wiring harness for a broken wire or replace the
harness.
