October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Valve Relay
- Remove valve relay. Using a DVOM, check resistance between relay terminals No. 2 and 5. See Figure. Resistance should be 64-84 ohms. Check resistance between relay 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 between terminal No. 2 and terminal No. 5. Check for continuity between terminals No. 1 and 3. Continuity should not exist.
- With battery voltage applied between terminal No. 2 and terminal No. 5, check for resistance between terminals No. 3 and 6. Resistance should be zero ohms. If relay does not test as specified, replace relay.
