I have what i believe is an 05 or 06 Softail. I bought the bike completely customized and dont really know much about it. Heres the problem. The battery seems to be discharging slightly. Under the seat there is a small white box w/ a printed circuit board inside. it had 2 violet colored wires and a black wire, coming from a plug connector. They all have broken off the board. What is this, and is it the problem?
