2. Inspect Circuit Opening relay
(a) Inspect relay continuity




- Using and ohmmeter, check that there is continuity between terminals STA and E1.
- Check that there is continuity between terminals +B and FC.
- Check that there is no continuity between terminals + B and FP.
^ If continuity is not as specified, replace the relay.
(b) Inspect relay operation




- Apply battery voltage across terminals STA and E1.
- Using an ohmmeter. check that there is continuity between terminals +B and FP.




- Apply battery voltage across terminals +B and FC.
- Check that there is continuity between terminals +B and FP.
^ If operation is not as specified, replace the relay.

3. Reinstall Circuit Opening relay
