1977-78 Models

  1. Locate amplifier at rear of speedometer. Set circuit tester on DC range and connect test leads between amplifier and throttle opener solenoid. See Fig 1.
  2. Turn ignition on. Tester pointer should deflect when ignition is turned on. If pointer does not deflect, and solenoid and speed detecting switch circuits are okay, replace defective amplifier.
