Where do I start?  Last Sunday I was towing the boat and the nut that hold the ball on the hitch came loose dropping the front end of the trailer to the ground.  It ended up wedged under my bumper snapping the emergency brake line, broke my trailer light socket, slightly damaged my two cables.   Unfortunately to fix the emergeny brake line I have to get a whole new coupler which will be about $850.   I got the light fixed and got a new ball and then I took a couple friends out to Sawyer and after a few hours of having the lights on it drained the main battery.  I jump started the boat using the other batteries and last night I went out and found the the battery was drained on my trolling motor.  To make sure it was the battery and not the trolling motor that was broken, I hooked the cables to the cranking motor and the trolling motor worked.  So we called it quits and that night the trolling motor didn't work at all even when it was hooked up to the other battery.  I charged it over night and this morning, still not working.  Not only that, but the foot pedal is stock and wont move at all.  What do you guys think is the problem?  Did I damage something when I jumped the main battery?  Also, my gas gauge doesn't work now either.  The only thing good out of all this is that I am still catching fish.

Mine is a motorguide and I think it is a 3 prong.  Thanks for the offer and advice and I'll take it look at it later.  Hopefully it's something simple.
