- Locate and remove starter relay. Starter relay is marked "ST". See COMPONENT LOCATIONS . Using ohmmeter, verify continuity exists between relay terminals No. 3 and 4. See Fig 1. See STEP 1. Continuity should not exist between terminals No. 1 and 2. If continuity is not as specified, replace relay.
- Check relay operation by applying battery voltage to terminals No. 3 and 4. See Fig 1. See STEP 2. Continuity should now exist between terminals No. 1 and 2. If relay does not test as indicated, replace relay.
