This switch functions magnetically. Do not use magnetized tools near this switch.
1. If the switch is open when the clutch pedal is released, speed control will not operate. This must be corrected before making any other tests. Use only a multimeter of 5000 ohm/volt rating or higher when performing the clutch switch test.
2. Disconnect switch pigtail connector from speed control harness connector and 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, remove and replace switch.
