Electric Tongue Jack does not work

Our trailer is 1 year old and since the day we brought it home the electric tongue jack does not work unless plugged into the truck. I know I can have them fix it on warranty but the location is hours away from where we live. Does anyone have any ideas as to what the problem might be? We don't see any loose wires. Thanks

These tongue jacks usually only have two wires, Positive and Negative. Just follow the wires and figure out where they are going. Since it works, I doubt it is a loose wire. Most likely, wired wrong from day one.

My jack only has one wire (for 12V positive) and grounds through the frame. Sounds like the ground is bad. When plugged into the tow vehicle, you are grounded to it. I used to have problems with mine, so I added a ground wire from one of the bolts connecting the the jack to the frame to the battery negative. The other possibility is that your trailer battery does not have enough charge and there is not enough voltage to run the jack motor.

Be sure you cover the power tongue jack because they are not waterproof and many will seize.

So... the only time the electric jack does not work is when you try to use the jack using only your trailer battery?

Do your trailer 12volt lights and fans work with the trailer disconnected from your truck?

Does your jack work when connected to shore power?

If fuse was blown, it wouldn't work regardless, not blown fuse. Works when plugged into truck.

Does it work when plugged to shore power? If it does I'd say a weak/dead battery or bad ground.

I don't think grounding is the issue. But to ensure, when hooked to the tv, remove one or two of the bolts that secure the tongue jack to the frame. Then sand the frame's underside to expose the steel frame. When reinstalling the bolts install a star washer between the frame and nut. This will give you a solid ground.

I think the issue is with your power feed. Check the wire routing that powers the jack, trace it back to the battery. It should go directly to the battery, ideally with a fuse,, nothing else shold be in between. If that is not the case I suspect that is your issue.

Actually it will work when plugged into the truck with the fuse blown, I discovered this recently. Apparently there's a separate connection?

I had this same problem, it was a blown fuse. If you raise the jack beyond the top, the fuse will intentionally blow to prevent damage.
