I have a wfco converter and it does blow the fuse if you reverse the batt. leads for sure your converter should be real close to the breaker panel my first rv it was under it easy to see . My 2014 keystone is behind the wall and you get to it from the basement storage area. my dealer blew the fuse when he had kid installed batt. when we had the walk throuh nothing worked.Thats how I know about it.
What does a converter look like?
there is nothing near the breakers/fuse panel other than an lp gas detector. I even unscrewed the panel and looked behind. Nothing but wires and dust.
