Jumper cables from the truck battery to the battery terminals on the trailer. Like the above post states, don't let them touch anything else metal. And I would unhook the A/C power before doing it.

With the battery not there, collect all the wire terminals that go on its positive post and join them with vise grips or a nut and bolt.

Now the converter will have a path to the jacks. This assumes the jacks are on a different wire that goes to the positive post. Assumes the jacks and the converter each has a negative path to the frame.


I will try that in spring. The trailer is good where it is and I am not running power to it this winter.

My plastic battery box is screwed down, so as long as the +ve does not touch those screws or the -ve wires, I am good.

It depends on the details of how its wired. If it connects directly to the battery (perhaps sharing the connection for the breakaway brake system), then it makes perfect sense. I suspect it is normal for your trailer.

Actually, that seems like a good setup to me, at least in general concept, as it helps to prevent someone from pulling the trailer without a battery for the breakaway brakes.


The breakaway does not work like that. It requires battery power to activate the brakes. And the jacks have a manual over ride. So the lack of battery is probably not a good theft deterrent.

Same here. Won't work without the battery

I wasn't meaning as a theft deterrent, but as a bad choice deterrent, though that probably wasn't the clearest from what I wrote. That is, in case someone wishes to move their trailer from here to there but doesn't care to be bothered to install the battery (or replace a dead one), and so pulls it without a working breakaway brake system. Having the electric jack operate in the same way makes that less of a desirable option and so might increase safety.
