Valve Relay
- Remove relay. Using a DVOM, check resistance between relay terminals No. 2 and 5. See Figure . Resistance should be 55-105 ohms. Check resistance between terminals No. 1 and 3. Resistance should be zero ohms.
- Check for continuity between relay terminals No. 3 and 6. Continuity should not exist. Apply battery voltage and ground between terminals No. 2 and 5. Check for continuity between terminals No. 1 and 3. Continuity should not exist.
- Check for resistance between terminals No. 3 and 6. Resistance should be zero ohms. If relay does not test as specified, replace relay.
