I have a Minn Kota 3 bank , 10 amp per bank battery charger.It is about 1 1/2 years old. It worked fine until last week when the red light on bank 3 went on, telling me to check connection. The fuse in the in line holder was burnt, I replaced it , but when I went to hook it back up it sparked and burnt the fuse again.I didn't mix any wiring or anything like that. I took the leads off of bank one and put them on the battery in question with no problems.Does this mean that bank 3 in my charger has gone bad? Any help or advice would be helpful. Thank you and Happy Memorial Day to everyone.

I doubt that your charger is bad. Check with MinnKota tomorrow.
