My BMV-602 has stopped displaying current. I have just replaced all my battery and alternator wiring.
In replacing your wiring, are your sure that the shunt has not been bypassed in any way?
The other possibility is that one of the contacts on one of the RJ12 connectors is not making contact somehow and thus preventing shunt measurement from reaching the BMV.
Shunt isn't bypassed but a poor connection at the RJ12 is possible.
I don't know how to test that other than having a new end put on.
