Testing Circuit Opening Relay
3. Check that there is continuity between terminals +B and FC. Check that there is NO continuity between terminals +B and FP.
4. If readings are not as specified, replace the Circuit Opening Relay.
5. Apply battery current across terminals STA and E1.
6. Using an Ohmmeter, check that there is continuity between terminals +B and FP.
