Replaced batteries and nothing works.......cables reversed??
If you hooked up the new battery cables reversed you probably blew the 'reverse polarity' fuses located on converter (large 30A or bigger fuses---2)
Converter could be faulty, reverse polarity fuses blown, battery disconnect switch OFF.......any/all could be your problem(s)
