So I took my boat to the shop they installed a dual battery setup
And isolation switch I went to hook up some lights the other day and something went wrong my bonding wire on my outboard burned away , has the boat shop connected up something wrong ?

I have no clue about boat battery, but sounds like you need to go back to the shop.

The earth bond on the outboard burnt away?

That doesn’t sound healthy. Not sure how that could have happened unless somehow the main negative is loose/high resistance join or something.

What did you do?
