Idle Switch

  1. Turn ignition switch to "OFF" position. Disconnect ISC servo connector. Check for continuity between pole "2" and injection mixer body.
  2. If continuity exists when throttle valve is placed in idle position and if no continuity exists when throttle valve is open (so that lever leaves idle switch), switch is good.
  3. If continuity exists when throttle valve is in both positions, contacts are bound together. If no continuity exists when throttle valve is in both positions, grounding is defective. Replace ISC servo assembly.
