Weekend Warrior Converter Issue

I have a 2007 Weekend Warrior 3305 5th wheel toy hauler.

I am not the original owner to make that clear. Batteries (it has 3 6v batteries) were replaced in 2017 I was having some ground issues so I cleaned all the battery cable connections and found a bad jumper cable so I replaced it. I also replaced a blown fuse I found on the converter. It was 2 green 30 amp fuses. Only 1 was blown. I replaced the fuse and was surprised to have working lights off of shore power. The batteries were not charging off of shore power in the first place. (obviously the fuse was the problem.) it worked great for about 15 minutes and then the same fuse on the converter (only 1 fuse) blew again. Any ideas why?


All the batteries combined were making 8 volts. Maybe they are bad and overload the converter?
  • 3 six volt batteries?
    Normally they are in pairs because the systems run on 12 volts.
    Have you been running this rig for a while with 3 batteries?
    How are they wired?
