Upgrading to electric stabilizer jacks

I am currently adding Lippert electric stabilizer jacks to our toy hauler. What is the correct way to wire the 12V DC motor to my back up batteries. They are wired in series. Any suggestions are appreciated.

    My thought was that the title is wrong and should say: "Downgrading to electric stabilizer jacks."
  • Just understand that they're less stable than anything you're replacing now.
  • First, check Lippert's wiring diagram. There should be a mini-breaker for each jack (like the one's in an A-frame) plus a fuse as I recall. Our breakers are mounted on the side of the frame I-beam next to the jack. Fuse is for short circuit protection and breaker is for overload protection. I think some manufacturers don't install both though (big cost savings??). On a retrofit, you can run new pos. wire up to the A-frame and use an in-line fuse there (weatherproof).

    If you want to go a step further and get fancy, you could get rid of the metal 4x4 box in the A-frame, use a watertight PVC box and then install fuses & breakers in it along with splices, which is what I did.
