Circuit Opening Relay: Testing and Inspection
INSPECTION
Test Relay Continuity
1. Using an ohmmeter. check that there is continuity between terminals STA and E1.
2. Check that there is continuity between terminals +B and FC.
3. Check that there is no continuity between terminals +B and FP.
If continuity is not as specified, replace the relay.
Test Relay Operation
1. Apply battery voltage across terminals STA and E1.
2. Using an ohmmeter, check that there is continuity between terminals +B and FP.
3. Apply battery voltage across terminals +B and FC.
4. Check that there is continuity between terminals +B and FP.
If operation is not as specified, replace the relay.
