Valve Relay

  1. Remove valve relay. Using an ohmmeter, measure resistance between relay terminals No. 2 and 5. See Figure . Resistance should be 55-105 ohms. Measure resistance between relay terminals No. 1 and 3. Resistance should be zero ohms.
  2. Check for continuity between relay terminals No. 3 and 6. Continuity should not exist. Apply battery voltage between terminal No. 2 and terminal No. 5. Check for continuity between terminals No. 1 and 3. Continuity should not exist.
  3. Check for continuity between terminals No. 3 and 6. Continuity should be approximately zero ohms. If relay does not test as specified, replace relay.
