- Locate and remove starter relay. Starter relay is marked "ST". Using ohmmeter, measure resistance between relay terminals No. 3 and 5 without battery voltage applied through terminals 1 and 2. See Fig 1. Ensure resistance is within specification. See STARTER RELAY CONDITIONS . If not as specified replace the relay. If as specified go to step 2.
- Check relay operation by applying battery voltage through terminals No. 1 and 2. See Fig 1. Measure resistance between terminals No. 3 and 5. Ensure resistance is within specification. See STARTER RELAY CONDITIONS . If relay does not test as indicated, replace relay. If as specified, install relay.
STARTER RELAY CONDITIONS
| Ohmmeter Connection | Resistance |
|---|---|
| Terminal 3 To 5 With No Battery Voltage Applied Through Terminal 1 & 2 | 10,000 Ohms Or More |
| Terminal 3 To 5 With Battery Voltage Applied Through Terminal 1 & 2 | Less Than One Ohm. |
