Here's my problem: I have 2 Trojan T-105 6-volt batteries wired in series. When I hook up to AC power, the fuse gets extremely hot - so hot that the solder oozes from the ends of the fuse. But only when I hook to 120v AC. I called TrailManor, and they sent me a new converter (under warranty). I swapped out the converter with the new one. I'm still having the same problem. I'm going to run down the positive wire and make sure it's not shorting against anything. When disconnected from outside current, the fuse does not get hot. As soon as I hook up to outside power, the fuse gets hot. I had to replace the fuse holder as it got so hot that it melted the fuse holder. Instead of the glass, I went with the plastic fuses (30-amp). Still getting hot. I took a reading across the poles of the battery. When hooked up to outside power, it reads 12.93 volts. When disconnected from outside power, it reads 11.7 and I'm confused. I'm not sure if it's a short, I'm not sure if it's a converter issue. Something is making the fuse very hot when hooked up to outside power.

Does anybody have a clue as to what my next move should be?
