Immediately blows, with a snap/puff.
Going camping today so will not be able to give any more information until Friday after this answer.
After you installed harness you tested it by operation with trailer all worked.
So I am assuming all wiring is correct.
Fuse with a snap/puff tell me a lot of current. I am thinking a wire is pinched somewhere. ( maybe a motor stuck/jammed but don't think so)
I am having problems with plugging into TV and the 12 V inline fuse blows. The 4 pin connector for the Tail lights and battery in trailer have nothing to do with each other.
So now I need 2 wires pinch to each other. Not likely. I would come back to this later. look around the lift system of the pop top.
Now the 7 pin does have something to do with both. I am thinking the problem has to be around this adaptor cable.
My first check would be to make sure the charging pin of the 7 pin connector in not shorted to ground. I am thinking you have an adaptor cable 4 pin to 7 pin. Now plug in the adapter cable into TV and not connected to TT. The charging pin should be 12 volts or high resistance. I would also check all other pin for right operation with a meter.
If you find nothing, I am going to ask dumb question, got to do it. The 2 wire you took apart, are you sure you got the same 2 wires back together. Normally a problem like this is caused by some work we have done on the trailer. Have you changed any lights, drove any screws , or in any way pulled on some wires, added any equipment.
If you have not found the problem yet. now the hard part. You will have to follow the high current that is blowing the fuse. That means that you have to follow the wire and each time it split off you would disconnect and see which way the current is coming from.
Hope this help.
