Sounds like the jack has been damaged enough that it's time to replace it. Powered jacks have a screw that turns inside a threaded shaft that allow the jack to rise and lower. It sounds like that shaft has broken away from the rest of the jack and now when the screw turns it just spins in place.

I recommend the Stromberg Carlson Electric Trailer Jack - Drop Leg - A-Frame - 23" Lift - 5,000 lbs - Black, Item # JET-5000 as a replacement.

It has a lifting capacity of 5,000 lbs which would be more than you'd need but will ensure that the jack will operate quickly and last a long time.

Hello Brian, thanks for reaching out. That would be fine. There is really no need for a cut-off switch here but there is no reason why you can't use one. As long as the jack is connected to a 12v power source, it will operate as intended.

Hey Geoff! How do you like it so far? The wire on the #e23ZV is 12 gauge. You can add a fuse if you want but it isn't necessary since the jack has a 20A automatic reset fuse built in already. If you want to add one I would make it the same 20A.

Answer 12

Lippert does not offer a replacement inner jack tube for their jack 1817941. When a jack is damaged in this way (which is more common than you want to know) it really is best to replace the entire jack for safety reasons. The outer tube on your jack…
