Clutch Switch Test

CAUTION: This switch functions magnetically. Do not use magnetized tools near this switch.

1. If switch is open when clutch pedal is released, speed control will not operate. This must be corrected before performing any other tests. Use only a voltmeter of 5000 ohm/volt rating or higher when performing clutch switch test.
2. Disconnect switch pigtail connector from speed control harness connector, then connect an ohmmeter to two switch connector terminals.
3. With clutch pedal in fully released position, resistance should be less than 5 ohms. With clutch pedal fully depressed, circuit should be open.
4. If switch does not function as described, replace switch.
