Throttle Switch

  1. Ensure that throttle plates and throttle linkage are correctly adjusted. Disconnect battery ground cable and pull connector off throttle switch.
  2. Connect ohmmeter between terminal No. 17 and ground. See Figure. Meter reading should be very low resistance or zero. If reading is not very low, adjust throttle switch.
  3. Connect ohmmeter between terminal No. 9 and ground. Observe ohmmeter and turn throttle by hand. Meter needle should swing smoothly between very low resistance and very high resistance (to point on open circuit). If meter does not swing smoothly, replace throttle switch.
