I have a 2004 Bennington 2275RL with a 2006 115 Yamaha. I recently went down to install a new battery on the boat. I was an idiot without a flash light and in the dark put the cables on backwards. Realized mistake immediately with the spark. Hooked up correctly I have no ignition or trim. The accessories all work okay. Checked fuse near battery and those I could find under helm ...all were okay. What did I blow and where can I find it?
