Has anyone ever done this and had any problems?
I plugged my TT into my TV without the battery so I could run the tongue jack. I needed to get the trailer home and I didn't bring the battery with me to the storage lot (I keep it in the garage on a float charger). I know I shouldn't be towing without a battery, but I was in a pinch.
Anyway, when I plugged it in, I heard the fuse pop, made a mental note to check it out, and verified later when I had the battery installed and nothing would run. With the TV connected and no battery, everything ran fine, so my plan worked, but I can't think why the fuse would go? And after I put the battery back on and changed out the blown fuse, and plugged into the TV and everything was fine.
I don't know that it makes much difference, but there was a 35 amp fuse there when I bought it that got blown when I had a short in the cord, I couldn't find a 35 amp fuse, so I replaced with 30 amp.
