Circuit Opening Relay Inspection

INSPECTION OF CIRCUIT OPENING RELAY
1. INSPECT RELAY CONTINUITY:
(a) Using an ohmmeter, check that there is continuity between terminals STA and El.
(b) Check that there is continuity between terminals B and FC.
(c) Check that there is no continuity between terminals B and FP.

If continuity is not as specified, replace the relay.




2. INSPECT RELAY OPERATION:
(a) Apply battery voltage across terminals STA and E1.
(b) Using an ohmmeter, check that there is continuity between terminals B and FP.




(c) Apply battery voltage across terminals B and FC.
(d) Check that there is continuity between terminals B and FP.

If operation is not as specified, replace the relay.
