Battery change. Dead screen on BMV712
The first thing I would check is the inline fuse in the red wire that connects to the +B1 terminal of the shunt. Check the connection along this wire too.
Then also check that the RJ12 connections at each end of the grey wire that goes from the shunt to the BMV unit.
