Troubleshooting Powered Trailer Jack that Has Power But Won't Work

Question

Question:

I have an LCI electric tongue jack that will not operate electrically. I have traced the power cord to the housing and have power all the way to the housing but I have not opened the housing. The light does not work either. Could this be a switch, ground issue? Just find it odd if the motor has burnt up that the light doesn’t work either. Thanks for any help.

It could be a switch or ground issue pretty easily. Most powered A-frame trailer jacks ground through the mounting hardware so you'd want to make sure that the frame of the trailer is grounding properly to the ground harness of the trailer wiring.

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…

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…
