Using the jack without the battery

I removed my battery to get my RV ready for winter. I go to use the jack and it won't work. It didn't matter whether it was hooked up to AC power or plugged into my truck, it would not work. Is that normal?

  • Mine is wired directly to the battery. But I believe you can crank it by hand. No fun I suspect.
  • Are you talking about front jacks in a fifth wheel? leveling jacks? Converters vary in their power output (30 amp., 55 amp., etc.) and that may not be enough to power a jack motor.

    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.


    Unless you have a 3/4" socket. That's how I moved it.
