How did you hook up the batteries?

If that's all you changed I'd say there is a good chance it's got to do with it.

We wired them in a series circut so the voltage is the same. did this help?

Re: Blowing fuses

If you wired them in series you are now putting out 24V. Everything in your boat runs on 12V unless you have a 24V trolling motor. If not they should be in parallel. Pos-pos and neg-neg.

Yeah that was helpful to rule things out.

Is it all the switches, just one or a couple and which ones?
