table. Check for battery voltage at terminal No. 10 of relay connector. See Fig 1
. If battery voltage is present, go to step 3). If battery voltage is not present, check circuit between relay and battery, including fusible link No. 1. Go to next step.
- Apply battery voltage to terminal No. 10. Battery voltage should not be present at terminals No. 4 and 5. Apply battery voltage to terminal No. 10, and ground terminal No. 8. Battery voltage should now be present at terminals No. 4 and 5.
- Apply battery voltage to terminal No. 3. Battery voltage should not be present at terminal No. 2. Apply battery voltage to terminal No. 3, and ground terminal No. 7. Battery voltage should now be present at terminal No. 2.
- Apply battery voltage to terminal No. 9. Battery voltage should not be present at terminal No. 2. Apply battery voltage to terminal No. 9, and ground terminal No. 6. Battery voltage should now be present at terminal No. 2. Replace relay if it does not test as specified.
