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.

    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.
