Accelerator Switch

  1. Unplug accelerator switch connector. Connect ohmmeter to switch connector terminals and check continuity. With accelerator pedal at less than 3/4 stroke, continuity should exist (switch is on).
  2. With pedal depressed beyond 3/4 stroke, no continuity should exist (switch is off). To adjust accelerator switch, loosen switch lock nut and fully depress accelerator pedal. Turn switch until switch plate on pedal gently touches switch flange.
