Clutch Switch
The clutch switch is a normally open proximity switch
that is attached to the frame under the dash (Fig. 13).
The switch is in its normal open position as long as the
clutch pedal is released (clutch engaged). When the
clutch pedal is depressed (clutch disengaged), the pedal
is positioned close to the clutch switch causing the
switch to close. The closed clutch switch is used in the
starting interlock system to make sure that the drive sys-
tem is disengaged during engine starting.
Testing
1. Park vehicle on a level s urface, shut engine off, re-
move key from ignition switch and apply parking brake.
Locate the clutch switch (Fig. 13).
2. Remove hood (see Hood Removal in the Service and
Repairs section of Chapter 7 -- Chassis).
3. Disconnect the wire harness connector from the
clutch switch.
4. With the use of a multimeter (ohms setting), test for
continuity across the two (2) switch terminals. There
should be continuity (zero ohms) when the clutch pedal
is depressed and there should not be continuity (infinite
ohms) when the clutch pedal is released.
5. After switch testing is completed, connect the wire
harness connector to the clutch switch.
6. Install hood (see Hood Installation in the Service and
Repairs section of Chapter 7 -- Chassis).
