I would like to connect the battery monitor to my motorhome. I have four 6 volt batteries to create a 12 volt system for the houser. I am looking for a wiring diagram. I left the negative wire on the battery that created the 12 volt sytemd then ran a seperated 2/0 wire to the shunt, battery side. Then connected the motorhome ground to the other side of the shunt. The convert on the motorhome was overheating?
