I have a 07 moomba lsv. My alternator burnt out on me. I changed it out and I went to start it up on battery 1. When I turned the key I thought I herd the starter to to turn over but I don’t remember. But now it does nothing when I turn the key. When I switch to battery 2 or 1+2 it starts right up with no problem. Both batteries are brand new and fully charged. I can’t figure out the problem. Perko switch maybe?? Any help would be awesome thanks
