Intermittent electric tongue jack on 2018 Micro Minnie 2108DS

[Skipurple]

We own a 2018 micro mini Winnie 2108 DS. Lately our electric tongue jack has intermittently worked. When it’s not working, we have to manually lift or lower the jack. We’re wondering if this is a sign of the Jack motor starting to wear out or more likely an electrical short somewhere. Anyone else had this issue? This is not when we’re running off the battery but when we’re plugged in to Shoreline.

I would first consider it an electrical problem but not a short. Shorts are more prone to blowing a fuse, etc. while intermitten topen circuits can be quite common! So a short often has to has work done before it comes alive, while a wire or connections that goes open can rattle around a bit and get contact again!
A meter to test voltage is a more direct and quicker way but there are times when we can spot things by eyeball.
A big issue to keep in mind that it takes a full path from battery to the item and back to ground to make it all work. Don't forget to look at the ground path as well as the battery side.
We don't get good plans and drawings for the trailer group so some guessing is all we've got until you look it over.
Since you don't mention any otherelectrcial problems, can we assume the battery cables are all okay, good solid and clean? Maybe worth a look.
Then locate the wires at the jack and follow them, one to battery and the other will likely go to ground. There is also likely to be a fuse or breaker in the line as well.

There are many complaints from the trailer group about a bad desing used on the power for them as it puts a bunch of connections down on the frame near the front, kinf of under the propane tank? If you have that setup, it puts the battery connections in a pace that gets a lot of spray off the road and they tend to be a nuisance witing to happen as they corrode and either trip a breaker or go open more often than if they were in a dry spot! Look under there and if you spot several small red boxes, those may be various breakers and the connections are a problem.
I'd rather hope you do not have that but if y u have connections down on the frame, I would start the search there!

So appreciate your input !! Wish us luck

On an 8 year old trailer, you have a corroded/intermittent connection somewhere. Look at the wiring most exposed to weather. Dry corroded connections appear to be open wires. Wet corroded connections work intermittantly.

Thanks!!

Definitely check the mini breakers inside the front frame. They're not well protected and are prone to corrosion. There is one breaker for the jack, probably the most forward one. At least that's the way it's set up on our 2024 FLX.
