CC Battery Location

[Stephen]

My Batteries are located under my center console. I’m not getting enough current to my motor because of corrosion in the junction box. Would y’all recommend moving one battery in the transom, or redo battery cables completely?

It would be different if you were stranded and needed a get home solution. If you know the problem is corrosion, FIX IT, DON’T BAND AID IT. Some CC owners are moving weight fwd, not aft.

Sounds like you're sure the issue is in the battery selector switch? I had a similar problem, and was able to take mine apart, remove corrosion from contacts and lubricate the contact surfaces, and now it works great. You can usually put new lugs on your cables too, if there's corrosion and/or broken wire strands in there. As CT said, keeping weight forward is usually a good idea

Get 1/0 welding wire for the length you need from console to the engine..
As Terry said "find the problem" My guess is your wire is not big enough to carry the load..
I have two batteries under the console with a battery switch in with them..

You could also have bad grounds of which will corrode wires..

Just my 2¢ worth...

I have used welding wire as well and it works as a cheaper alternative to the tinned wire for the big stuff. I'd leave the batteries where they are as well.

Thanks Guys for all the input. I’ll just leave them forward and start by trying to remove the corrosion.....then go to re-wiring the cables.

Using welding wire will certainly work...in the beginning. I notice you are in Florida, and the salt air will quickly corrode untinned welding wire. It is more flexible because it has smaller strans and more of them than tinned battery cable. I predict you will soon have the same problems ( maybe a year or two). I would spend the money and buy the correct size tinned wire (Been there and done it, and have the T shirt and tow bill using welding wire).

This👆I was thinking same thing. Corrosion is a real issue here in Hawaii too. I just ripped welding wire out of some outboards. It was cracked, dry rotten, and missing insulation on a piece. It’ll work for testing but I’d do it right. The tin is there for a reason.

you guys are right...as I recently read somewhere once you have already spent 80K on a new boat whats another 10k lol.
