ok thanks, see I have been keeping that knob pushed in this whole time, which I am guessing is a constant feed to the battery, and maybe thats the problem. But wether its pulled out or in, the lights still flicker and dim, we use the trailer just about every weekend in the summer and it hasnt gone bad yet, but maybe the inverter is on its way out.
I also was messing around in the fuse box and like fuse 11 or 12 there isnt a fuse but the right light on it is always on, put a fuse in that slot and everything turns off, so I am guessing there shouldnt be a fuse in there, unless I have something wrong.
