Help with 12V

I need some advice or better understanding of the wiring for the 12V on my 1975 Silver Streak. All lights on the inside of the trailer have 12V. The issue is; there are three light switches on the right as you come thru the front door. 2 of them are for the outside light and they work fine. The 3rd switch, when I turn it on or off it turns all of the lights on the inside of the trailer off. It does not turn the 12V power because I can turn the lights back on by turning on the switches that are located on the lights. Also sometimes when I hit the switch it will blow a fuse in my convertor. I'm really confused with this switch. I'm not sure if it is wired right. I don't understand how I don't lose 12V power when I cycle the switch but the lights do go out. Also FYI I don't currently have a battery hooked up to the trailer. I'm not sure if this means anything or not. Any advice would be great.

Ok, First: TWO switches control the outside lights? That is different (unless one controls a light on one side and the other the other side, or a normal patio light and some big "Scare" lights)

Second: The third switch... I do not know how it can turn them off and you can still turn them back on less all the lights are either "Remote" (Never heard of that) or 3-way (Likewise) and if that were the case (3-way) Flipping that door switch would change the status of all lights.

That switch on my rig only controls 3 out of six lights by the way.

I suspect it is the battery disconnect and that is why when you re-connect if the batteires are very hungry they pop the fuse on the converter.
Home is where I park it!
