Remove the 5-pin connector from the controller. There will be three wires in it.

The throttle switch is an ON/OFF switch.

Use “Ω” setting on the meter.

Place one probe on the white wire and one on the chassis ground.

With the button pushed in (throttle fully returned) the meter should say “OL”.

With the button extended (throttle pressed), there should be a value shown close to
Zero Ohms (0Ω).

If this test result is good, the throttle switch is also good and does not need tested as
an individual component.
Throttle Position Sensor / Potentiometer

Use “Ω” setting on the meter.

Unplug the throttle position sensor from the harness.

Place one probe on the end of each wire.

With plunger extended (throttle returned), the resistance should be less than 160
Ohms (Ω).

Depress plunger by pressing down on the throttle pedal. With the throttle fully
