Need help with power tongue jack

[teddy]

I have a 2013 FR Sport 220 trailer. It came with a power tongue jack. I am not sure of the make and model. There was a paper label but it come off. It looks nearly identical to the LCI Lippert model with the LED light.

We have been out since April on a trip from upstate New York, across the US to Big Sur and up the west coast all the way to Alaska. We are in Yellowstone now on our way home. It's been an awesome trip.

The jack has, for the most part, been working OK. Every now and then when we are disconnecting or connecting, it stops working right in the middle of extending or retracting. Usually, I turn it off and on again and it comes back to life. That did raise a red flag but since it started up again and we are on the road, I didn't lose too much sleep about it. I've also twice noticed an electrical spark down near where the jack is bolted to the frame.

This morning the jack stopped working entirely. I checked the fuse and it was OK. I ended up manually cranking the jack and left the fuse out as a protective measure. Now this evening I reinstalled the fuse on a whim and sure enough, the jack functioned perfectly.

To me, the problem seems like a loose connection. But where? Before I disassemble the jack looking for a possible loose connection, I thought I'd ask if anyone else has had a similar problem or an idea as to what's going on.

Thanks in advance for your help.

Sounds like the loose connection is at the bolts where the jack bolts to the frame of the TT hitch area. Possibly some cleaning is needed where the bolts are, I would (while TT is mounted on TV) unbolt the jack and thoroughly clean the area where the jack touches the TT hitch area so you get good metal to metal contact (on my TT this is the ground that completes the electrical circuit) then tighten the bolts up good.

X2, If you saw a spark at the location where jack mounts to frame, I would agree that you have a poor ground. As suggested I would hook up to TV and then remove Jack and clean all the rust away so you have a good metal to metal contact between frame and jack mounting flange.

When I install my electric Jack I installed star washers between the bolt heads and jack base. I also installed star washers between the nuts and frame.

Thanks. I will check the ground connection.
