New Trailer.....No Power!
New Jayco owner! Just brought our new X19H home from the dealer. Drive was easy, the walk through was.....adequate. It has a power tongue jack which I thought was cool. Got home, started to unhook, unplugged from my van, started to lift up the jack to unhook the bars, hit the top of the extension and power cut. Now I have no 12v power anywhere in the trailer. I was able to hook the 7 pin back to the van to get some power to get it unhitched and leveled again. I called the dealer and they said if you hit the top of the extension on the power jack it will blow the 30A fuse. I pulled all the fuses in the box inside and they all look fine. The dealer said there may be another 30A fuse underneath the trailer and just follow the black wire, but I can't find anything. They also said there is no battery shut off to this trailer. I know I am a total noob but I can't see how I broke a trailer 10 minutes after getting home haha. Or, maybe I can. Perhaps I am supposed to leave it plugged into the tow vehicle or 30A any time I am using the power jack. Any help would be greatly appreciated.
Thank you.

Mine has an inline fuse on the positive line coming off the battery. It was approximately 18" from the battery box

X2 - on my 23RLSW model it's a little rectangular black fitting, soon after the battery. This is one of the most frequent issues we hear from newbies, sad to say! Apparently you'll blow the fuse when you hit maximum or minimum extension of the power jack.

Thank you! Does it look like a little black box with wires going in and coming out of it? Can you unscrew it to get to the fuse? And, is it a normal 12v 30A fuse that I can just pull out and put a new one in?

This is what it looks like on my 26BH. There is a cover that pulls off and there is a 30A fuse inside.

Just got my first trailer. This was a problem for me as well. The fuse for mine was tucked away a bit and not obvious. Get some extra 30 amp fuses, you blow will it again!! Search the forum, some have replaced the fuse with a circuit breaker.

That fuse will blow if you run that jack completely up, stop when it is clear from the ground and up high enough. There should be a line on the jack shaft coming down that shows you the top.
Add a few of those fuses to you tool kit that you will carry with you.

I fully retract my electric jack when I'm through with it after hitching up. I have done this for years and never blown a fuse. Can someone explain the difference between my situation and at the OP's?

Make sure you use slow blow fuses, this is what most jacks come with. They allow
a surge over 30 amps for a short duration without blowing, a regular fuse will blow when the jack draws to much power at the end of stroke. These are hard to find at part stores or dealers, I had to order online.

Sundancer - Very helpful. If that fuse ever does blow, I'll avoid using an inadequate replacement!

I would guess that (like me) you let go of the button as soon as the jack motor loads up. Rather than waiting for the no noise of the motor being completely jammed.

Absolutely. Same when operating the slides. DW thinks I'm too touchy when she lets the slide "bump" a few times. Nice to know my concern is justified.

I took a Sharpie and drew lines around my jack post about 1/4" from maximum extend and maximum retract and don't let the motor get loaded enough to blow the fuse.

I've never blown a fuse by holding the button too long. I've always let the slides "tick" a few times before letting go of the button and have never had a problem. The jack on the other hand, I've never drawn that all the way up. Interesting though..

Yeah, the slides have a clutch to avoid overloading the motor. The tick-tick-tick you hear is the clutch operating to avoid tearing apart the slide mechanism.
The jacks need to have 100% of the motor power available to overcome and unknown tongue weight.
The 30A fuse prevents the fire that will occur if the jack motor is jammed for more than a handful of seconds.
It's still good practice to listen to the motor/gear-train and let go of the button as soon as you hear something different/odd occurring. It will add quite a bit of service life to your automated possessions.

It is usually not recommended to run a jack screw all the way to either end. Aside from the blown fuse issue, it destroys the nut, which is often bronze or a soft metal of some other origin. Someday, you'll find your jack .... won't.

You can purchase slow-blow fuses at most any auto supply.

Depends what type of fuse you need. My Barker jack uses the old glass style fuse, 30 Amp MDL® Fuse which is a slow blow. I tried all the local auto parts stores, Lowes/Depot, I even tried the local RV dealer and he didn't have them. Only a few places online had them, DelCity.com has them in ten packs for $4.50
From what I saw nobody makes a slow blow fuse to fit ATC/ATM which is what most of the inline fuses are.

I am looking at a new 4500 pound tongue jack that has safe stop which wont allow it to bind or blow a fuse like the one on the tt now and I think that's a good idea
