Diverted Solenoid

  1. With engine at normal operating temperature, connect a voltmeter probe to light green wire at rear of solenoid plug (use jumper wire if required). Start engine and idle at 700 RPM. Battery voltage should be indicated during first 75 seconds of operation.
  2. After 75 seconds, voltage should drop to about one volt. Accelerate engine. Voltmeter should indicate battery charge and 75-second time delay should begin. If low voltage is indicated before 75-second delay, check for pinched wire in harness or replace extended idle relay.
  3. If voltage does not drop after 75-second delay test Open Loop 3 circuit. Refer to Computerized Emission Control in the AMERICAN MOTORS Section.  Replace open loop if defective. Connect vacuum hose and unplug diverter electrical connection. Connect test lamp to terminal of solenoid and positive post of battery. Lamp should light and vacuum should be present through solenoid. If not, replace solenoid and/or locate air leak. If solenoid operates normally, replace extended idle relay.
