  2. With battery voltage applied, air should pass through solenoid. Disconnect voltage to solenoid. Ensure air does not pass through solenoid. Replace solenoid if defective.
  3. Using ohmmeter, measure resistance between case and solenoid connector terminal. Resistance should be 11-15 ohms. Replace solenoid as necessary.
