I am new to the bass boat scene and just bought an 89 winner tournament 2000. in various places on the boat are battery charging ports. How can I find out if these work, and the info on getting them to work. The plug on these isnt like any normal plug in I have seen. Just two prongs. I have seen no extra wires to my batteries other than the pos and neg needed to power trolling motor batt, starting batt, and acc batt. Is there anyone that can help?
