Vacuum Line Control Solenoid Valve (Justy Carbureted)

  1. Connect ohmmeter leads between terminals of solenoid. If resistance is not 10-100 ohms, replace solenoid valve.
  2. Using an ohmmeter, ensure windings are not grounded. Apply battery voltage to valve terminals. Ensure passage opens and closes as voltage is applied and removed.
  3. When solenoid is not energized, passage between "A" and "B" should be closed and passage between "B" and "C" should be open. See Figure . When solenoid is energized, passage between "A" and "B" should be open and passage between "B" and "C" should be closed. If solenoid valve does not operate properly, replace solenoid valve.
