Wiring Negative Wires Through a Battery Monitor?


Hi, I have a question about my bmv-712 battery monitor.  The only thing that doesn't have the negative going through the shunt is the starter/alternator.  Do I have to change this? - Steve


With battery monitors, including your BMV-712 model, absolutely no negative wire can bypass the shunt. Specifically all DC negative connections need to be on the load side of the shunt and not on the battery negative post. Otherwise any discharging from running your engine or any battery charging from the alternator will not be counted, resulting in wrong battery monitor info. - Jeff
