I have
factory reset to no avail. I have set all the individual parameter manually to no avail. Disconnected the BMV - no change. Connected to a new shunt no change. Connected to new battery - no change.
It just continues to display system voltage in the high 70s to low 80s. I have replaced with a newer model 712, but would like to know what the likely cause of this malfunction is to ensure that I don't suffer this failure again.
thanks
