COMPONENTS

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 no continuity, replace the relay.
b. Check that there is no continuity between terminals 3 and 4.
If there continuity, replace the relay.




3. INSPECT CIRCUIT OPENING RELAY OPERATION
a. Apply battery positive voltage across terminals 1 and 2.
