AIS Motor

  1. Turn ignition on but do not start engine. Visually check position of throttle arm at AIS motor. Arm should be pointing downward and toward rear of engine.
  2. If throttle arm is in correct position, check ballast resistor. With ignition on, measure voltage between pin "A" and ground, then between pin "B" and ground. Voltage at "A" should be 6 volts, at "B", 10 volts. If not, check wiring harness.
  3. Resistance (with connectors removed) between pins "C" and "D" should be 9-11 ohms, and between "D" and "E" should be 4-6 ohms. If not correct, replace ballast resistor.

  4. If arm at motor was in correct position, disconnect 10-pin connector at computer. Connect a voltmeter between pin 6 of connector and ground. At least 8 volts should be present. If not, check wiring harness. If harness is okay, replace AIS motor.
  5. If 8 volts were measured at pin 6, computer must be replaced.
