CIRCUIT OPENING RELAY
INSPECTION
1. REMOVE RELAY BOX COVER
2. REMOVE CIRCUIT OPENING RELAY (Marking: CIR
OPN)
3. INSPECT CIRCUIT OPENING RELAY
(a) Inspect the relay continuity.
(1) Using an ohmmeter, check that there is continuity
between terminals 1 and 2.
If there is no continuity, replace the relay.
(2) Check that there is no continuity between terminals
3 and 5.
If there is continuity, replace the relay.
(b) Inspect the relay operation.
(1) Apply battery positive voltage across terminals 1
and 2.
(2) Using an ohmmeter, check that there is continuity
between terminals 3 and 5.
If there is no continuity, replace the relay.
4. REINSTALL CIRCUIT OPENING RELAY
5. REINSTALL RELAY BOX COVER
