Level Up System Blowing Fuses..

2017 Sandpiper FLOK having an issue with the Lippert Level Up Jack system. I believe I have narrowed this down to the inline fuse blowing every time the camper is plugged into shore power. Once you are all ready to go and need to put the Jack's up the control head will be dead and the inline fuse that's by the hydrolic tank will be blown.

In addition, when raising the Jack's, one jack will go up or half way up and then the control head will go blank and reset. You will need to power it up again and repeat the process sometimes three times to get all 6 Jack's up.

Opinions?

Maybe try a higher amperage fuse?

They also have circuit breakers you could use rather then a fuse.

Level-Up for towables is 12V and requires the batteries to be at or near full capacity. My 1st suggestion is to unplug the control module and wait a few minutes. Then plug it back in. While you are waiting would be a good time to check ground points, connections to the solenoid on the pump motor and your batteries.

I will give the disconnect a try. The batteries have always been at capacity when the event has happened as this only happens after the camper has been connected to shore power for a period of time. Plug into the tow vehicle.. no problem. Let it sit for a few days on 12v power... no issue. Plug into shore power for a few days...fried fuse.

Hmmm, Iím wondering if a surge from your converter/charger can do that??? (thinking out loud)

I've been hooked up to my EMS system so it's not a surge from my house or from any of the campsites. It could be the converter perhaps. This past week while on a trip we lost all AC inside the camper yet had it at the pedestal. None of the breakers were tripped by sight. I flipped them all however and everything came back to life when I was done.

So the question would be is the converter pumping too much DC at the level up as its drawing to operate?

The level-up does not draw power from the convertor. It draws from the battery(s). My thought is that when the pump is activated while you are connected to shore power, you might be getting a surge from the charger that is causing the failure. It’s just a theory and I have no idea how to test it. Your EMS will protect only the 120v side from spikes.

No...I'm not activating the level up while connected to anything. It's running strictly off coach battery.

So here is the way this goes... plugged into shore power get ready to leave, unplug everything and the rig is sitting there and I want to raise my front end to hitch up and the panel is dead and the fuse is blown. Replace fuse... the screen dies and resets over and over as each jack raises.

We drive wherever and I unhook from the TV and go to put the levels down, no problem everything works fine during the auto level process.

Plug into shore power at the new location and it all starts again with blown fuse.

I’m asking myself “How does plugging into shore power blow the 12V level-up fuse?”
I ran that question over and over. The only link between the 120v system and the level-up that I can think of is the converter/charger. Since it is amperage that blows the fuse (not voltage) the question now becomes; “How does over amperage get to the level up and blow the fuse?” I cannot answer that without testing circuits. However, you threw in a variable. The LCD panel blanking out as each jack operates. So you replace the fuse and the system works but not correctly and as you stated, you are not plugged in to anything. So how can you draw a line between all these events? The only common point between all these things that I can think of is the ground. Then I consider the other things you mentioned like temporary loss of AC power and everything works normally after bouncing down the road for awhile. I put all this info in my spin cycle and it comes out with: Loose ground connection. Thats my best guess.
What kind of fuse is the one that keep blowing? (type, amp rating & voltage)
Hope this helps you track down the malfunction.
