DogDoc, pull the clutch switch off, spray it thoroughly with some spray contact cleaner and work the actuator pin a few times while spraying the cleaner into the switch. Get your analog ohmmeter out, set it to the lowest setting, put the probes to the 2 blade connectors and watch your meter as you actuate and let go of the actuator pin. You should get a ZERO reading with the pin pressed in......and an infinity reading when the pin is out. The meter needle should move abruptly from 0 to infinity with no jerkiness.
