Clutch Switch: Testing and Inspection

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 the clutch switch test.
2. Disconnect switch pigtail connector from speed control harness connector, then connect an ohmmeter to the two switch connector terminals.
3. With clutch pedal in the fully released position, the resistance should be less than 5 ohms. With clutch pedal fully depressed, the circuit should be open.
4. If switch does not function as described, replace switch.
