I just bought this boat and had to install a new live well and bilge pump. There was no power getting to the pumps. The switches on the dash were lit up and the motor cranked, acc switch lit, and horn worked. Battery is good. There are two wires black and red on the hull floor that I assumed went to trolling motor on front (another story for another time). I connected these to the battery along with the main leads to the motor. Now the whole boat is dead. What did I short out and where is the fuse?
