Tons of bad "crap" "info" out there.Conflicting info I am seeing. Some say you can’t tend just the main battery as it won’t charge the aux. which is what I have been seeing since I started using a fender. Mine is wired to the main batteries positive and negative posts.
The two batteries ARE absolutely connected together. Any tender WILL charge both.
If yours is wired that way you are charging both. Do not connect to the negative post directly. Only the top studs.
