Burbman thanks so much for the info. That is what I was thinking too. If the battery was able to last for so long, it probably isn't a breaker or fuse. I will definitely contact Best Converter. I am pretty handy so I will probably be able to replace it myself. Heck I can replace ceiling fans so hopefully I can figure this out. Now just another question......could it really be a bad connection or loose connection from the trailer to battery or the converter wires? The reason I am asking this is because the site that the trailer sets is waterfront....salt air not too good but would the battery really have made it for that long if it was a bad connection. Thanks!!
