INSPECTION




1. REMOVE CIRCUIT OPENING RELAY




2. INSPECT CIRCUIT OPENING RELAY CONTINUITY
a. Using an ohmmeter, check that there is continuity between terminals 1 and 2.
If there is no continuity, replace the relay.

b. Check that there is no continuity between terminals 3 and 5.
If there is continuity, replace the relay.




3. INSPECT CIRCUIT OPENING RELAY OPERATION
