COMPONENTS FOR REMOVAL AND INSTALLATION

CIRCUIT OPENING RELAY INSPECTION

1. REMOVE CIRCUIT OPENING RELAY
2. INSPECT CIRCUIT OPENING RELAY





A. Inspect relay continuity
(a) Using an ohmmeter, check that there is continuity between terminals ST and E1
If there no continuity, replace the relay.
(b) Check that there is continuity between terminals +B and FC.
If there no continuity, replace the relay.
(c) Check that there is no continuity between terminals +B and FP.
If there no continuity, replace the relay.





B. Inspect relay operation
(a) Apply battery positive voltage across terminals ST and E1.
(b) Using an ohmmeter, check that there is continuity between terminals +B and FP.
If operation is not as specified, replace the relay.
3. REINSTALL CIRCUIT OPENING RELAY
