Re: When on shore power why do I always see charge going in?
When I shore power, I have never seen less than 2 amps charging, but also take note that the voltage showing on the BM is the float voltage setting of the charger.
If you have 2 Amps but at say 14.8 volts, you might have a problem.
On the bright side, only 49 or so things to get to grips with
Is it possible you have a load bypassing the shunt?
Even when "full" batteries will take some current. Healthy batteries will drop into the tenth or hundredth of an amp acceptance rate but sulfated batteries can take more for longer...
It is also possible your chargers power supply is simply switching on and off to maintain voltage and not over shoot it. Many chargers have rather poor low current resolution. Watch the ammeter and see if it occasionally blips off then back on..
