Thanks for the info. We don't mean to nag, but each question is sparked by an idea in someone's head, and if you don't answer, we can't proceed.

Sadly, this doesn't tell us much other than the wires are at least somewhat connected. This is a good thing to know, but it doesn't tell us how good the connections are. An LED requires only a tiny amount of voltage / current to light up. Most of them will continue to light at 5 volts or so, and they require only a few 10s of milliamps of current. The jack motor requires around 1000 times as much current, and voltage near a full 12 volts.

So this brings us around again to the question of "do you have a good ground between the jack itself and the actual frame of the trailer", (not the swing tongue). The ground connection could be ratty/rusty/corroded/loose, and still pass enough power for the LED. But the voltage drop through the crummy ground will starve the jack, and it may not even twitch. This is a relatively common problem, easily confirmed or denied, and easily fixed.

Earlier posts point toward charge/discharge problems, and I have no problems with any of that. But the ground connection to the jack is easy to check, and if it eliminates one possible symptom, so much the better.

I hope your back surgery goes well. Get back to us when you can, and with your help, we will continue to scope this out.
