I need some help please, we have had a bmv700 in our boat system for a few years now but have never been able to get the BMV to read the amps coming from the two alternators, every other load, charging system shows up nicely,, its a 12v system with one 800amp battery bank, two 85amp alternators which are grounded through the engine case to the neg side of the batteries with external Hella HPR 3 stage regulators on each alternator, my problem is I can't for the life of me work out how I can get the BMV700 to read the amps that the alternators are putting into the batteries so at the end of the day the BMV is reading a neg amp draw not knowing that the alternators are actually charging the batteries, is there anyway of getting a chassis ground alt to be connected to the load side of the shunt? I'm very confused and need some positive advise.
Rod.
