Throttle Switch
Detach cover from throttle switch and make sure that there is a sound when accelerator pedal is depressed. Inspect clearance between cam body and micro switch body with a feeler gauge. The clearance should be 0.0315". If clearance needs adjustment, loosen adjustment screws and turn switch to achieve clearance, tighten adjusting screws. Disconnect coupling and connect ohmmeter between terminal "1" and terminal "2". Meter should indicate zero. When accelerator pedal is depressed even slightly meter should read infinity. If switch does not function properly it should be replaced. Connect meter between terminal "1" and terminal "3". When accelerator pedal is not depressed at all, or is fully depressed, meter should read infinity. It should read zero when pedal is partially depressed. If switch does not operate properly, replace switch.
