Switch Testing
Oil Level Sensor Testing (2 Stroke Models)
1 . Disconnect PurpleIBlack and Rec:ilWhite sensor wires.
2.
Test for continuity between the wires with the float on
the bottom (oil level empty or low), and off the bottom
(safe level).
3.
The wires should have continuity when oil level is low
or empty, and no continuity when float is off the
bottom.

Oil Level Warning Light Testing (2 Stroke Models)
1.
Disconnect Purple/Black and RedlWhite wires from sensor to remove the sensor from the circuit.
2.
With ignition key off, connect the wires (on the harness side) together.
3.
Turn key (and auxiliary switch) on. The light should illuminate. If not, check for battery voltage on RIW wire to
sensor, check bulb condition, and related wiring.
Coolant Temperature Sensor Test (Hot Light)
With the ignition switch (and engine stop switch) "ON", power is delivered to the hot light via the RedlWhite wire.
The BluelWhite wire (ground) out of the light socket is connected to the coolant temperature sensor on the cylinder
head. In normal operating conditions, the temperature sensor is non-conductive (open). If engine coolant reach-
es the specified temperature, the sensor becomes conductive completing the ground path for the light.
With engine cold, disconnect lead and measure resistance of sensor between connector terminal and ground.
There should be no continuity or very high resistance (megohms). To test the HON" temperature, heat the switch
in a water bath to the temperature shown in table below. The switch should become conductive (low resistance)
at indicated temperature. Do not immerse switch past the threads or allow switch to contact container when heating.

Hot Light Circuit Test
Disconnect temperature sensor wire lead and short it to ground on the cylinder head. Turn key and auxilliary
switch to "ON" position. The hot lamp should come on. Check the bulb and related wiring if the lamp does not
illuminate.
