Clutch Switch

Ensure pedal height, free play and push rod play are correct. Verify engine does not start when clutch pedal is released. Ensure engine starts when clutch pedal is fully depressed.
If system is not operating correctly, ensure continuity exists between clutch switch terminals when switch is depressed and does not exist when between clutch switch terminals when switch is released. See Fig 1. Replace or adjust clutch switch as necessary.
