I have a BMV-712 smart connected to two 110AH lead acid leisure batteries joined in parallel and at 12v. The battery side of the shunt is connected to the leisure battery neutral and the load side is connected to the chassis of the van. All loads to do with my van connect to the chassis (and so to the shunt). I have nothing connected to the two little screws on both sides of the shunt.
The consumed A/H consistently reads zero and the time remaining is at infinite. I have taken two screen shots which may help. As in previous answers to this type of question, the connections are correct, so I can’t quite understand what’s going on. I would be grateful for any help.
