CIRCUIT OPENING RELAYINSPECTION
1. REMOVE CIRCUIT OPENING RELAY FROM ENGINE ROOM J/B NO.2
2. INSPECT CIRCUIT OPENING RELAY CONTINUITY
a. Using an ohmmeter, check that continuity exists between terminals 1 and 2.
If no continuity exists, replace the relay.
b. Check that no continuity exists between terminals 3 and 5.
If continuity exists, replace the relay.
3. INSPECT CIRCUIT OPENING RELAY OPERATION
a. Apply battery voltage across terminals 1 and 2.
b. Using an ohmmeter, check that continuity exists between terminals 3 and 5.
If no continuity exists, replace the relay.
