Connected battery wrong on my new boat, now nothing works?

Question

I got a new boat. It has electrical system on it for playing a stereo, watching tv, other things. It uses a battery to run all these things. I accidently connected both connections to the positive post. There was alot of sparks, and smoke. Now nothing electrical works inside the boat. I changed the fuses and such, but I noticed alot of the wires inside have been burned. Is this expensive to fix?

Answer 1

This doesn't make sense. Both leads were connected to the same voltage,(12 volts+ dc) therefore no difference in potential. You need to always have a difference in voltage for energy (ie burnt wiring) to occur. I would have to check but I don't think this should hurt anything. Also, how did you get both terminals on 1 post? Steve

Answer 2

There should be a main breaker that tripped before major damage was done to those components. Try finding it and resetting, then check out the systems for damage.

Answer 3

Way to go Ace. You fried anything that is transistorised as well as the starter and the alternator along with your wires.

Yeah, it's gonna be a real expensive fix. Good luck.

Answer 4

Yep. Probably needs to be completely rewired, not really a backyard project. Take it to a marine shop for a guestimate.

Answer 5

You probably just blew a fuse.  Find your main fuse and see if its blown.
