As I stated before: If your charge leads are not hooked up properly, the shunt cannot read your charger input. Only need to change the NEG charger lead to the Neg output of entire battery pack after the shunt. Your battery pack is an entire package not just one cell or one battery. The shunt is only a counter to count amps either in or out. All of the power from or to the battery goes thru the NEG terminal. The charger must be after the shunt!!!! This is so the shunt can read amps in and out of the battery. If you do not put your charger neg after the shunt it cannot read the input charge to your battery. This is why your system is only counting amps out and not counting amps in (charging). See your manual.
