Angry First trip, tongue jack quits! ARGGG!

Looking for some help or tips. While unhooking at our site in St Augustine FL for our first trip with our new (to us) 2013 Laredo 291TG, the tongue jack stopped working with the tongue all the way up. Figured out how to manually operate it, but now trying to see if it is repairable. Neither the jack motor or light will come on like there is no power to the unit, and there are no blown fuses. Plenty of 12VDC available, but how do I get the cover off to see if power is getting to the jack motor/switches? I have a couple days to mess with it, but if all else fails, I can do it manually with my drill.

Check for an inline fuse. It may have blown for some reason. Also check to see what else is not working, you may have tripped a circuit breaker on the underside of the a frame tongue of the trailer or frame.

Typically, there's a breaker that runs to the jack.

Check the ground wire and the positive wire. I thought mine stopped working one time and it was the positive wire wasn't clean or something and not making a good connection even though I had it on the battery tight. I scraped it with blade real quick and put it back on, and its be fine ever since. I am the original installer of it though, and mine runs to the battery, yours might be connected differently.

If you have a meter handy, you might be able to check on the terminals before you remove them to see if there is voltage. That could help eliminate something. I would say you could even poke through the wire if your probes are sharp enough, but the danger there is you will allow water into the wire and it can and likely will corrode at some point.

I think my husky just has some screws that hold the covers on, if you can find them. If you google yours you might find some help online with a video or something.

On the front bulkhead of the trailer (trace the positive battery cable to lead you to the exact location) you'll find two 30 amp "auto-reset DC circuit breakers". Check them for function, One will have the positive cable from your electric jack connected to it, follow that cable to check for an inline fuse, but chances are you won't find one. You will probably find either a defective circuit breaker or a loose connection to the jack cable end. Here is a picture of what you'll find at the end of the positive battery cable. There will probably be a red plastic cover on the circuit breakers to protect the terminals from getting wet.

I see you have a Silverado as a TV. Make sure your truck is off when plugging/unplugging TT. My Silverado use to trip the circuit breaker every time I hooked/unhooked my TT with the truck running.

My jack has an in-line fuse, near the A-frame of the trailer, I usually take it out when the trailer is parked.

I will simply regurgitate the same info as others. My power jack is wired directly to my battery with a dumb glass inline fuse. Blew it out in the middle of nowhere of course(2 hour round trip to nearest parts house). Now I keep a 5 pack of glass fuses in the kit. I used a bobby pin from my wife and completed the circuit as I realized it was operator error. I was extending while still hitched to take some load off of WD bars and wasn't paying attention. Started lifting truck and amp load went high.
I have never tried it but if jack gets to full extension and you keep operating switch is it possible amp load could go up and blow fuse??

Yes found that out the same way. Now there is a paint strip on the max up and down before the fuse blows.
