LCI Motorized leveling

[Pauline]

My jacks are up but the "jacks are down" light is on. The fluid is full so that leaves the pressure switch I think. Before I pull the switch is there a fuse that might be out?

Did you try and cycle the jacks? Sometimes mine used to not come all the way up and had to auto level then retract all to get it done.

Before you pull that switch: make sure you disconnect the battery connection to the pump. It will start auto to maintain system pressure. Yellow switch on manifold senses when return oil pressure falls to 1500 psi. Leak or jack out of home position will cause the light to come on. System return pressure always on about 1800 psi to balance jacks extended or retracted.

Yes, I had to manually retract them twice. When I tried the retract switch all the jacks went down to there max.

Thanks VinceU, Would I be able to drive MH if I can't fix the problem. (if I disconnect the battery to the pump). I may have to have someone else repair this. Does replacing the switch sound like the right thing to do?

Why don't you contact the jack manufacture first, they know all about there product and will be able to tell you if it can be fixed over the phone or will have to be taken in or have a mobile service come take a look.

You should be able to drive it with all power off the system. You can have the jacks secured with wire or web belting as insurance.

Also in your last post you said the jacks extend when you push retract. I had that happen a few years back. It was an electronic failure causing the pump to always extend. Temp fix is to remove the pump connector on the manifold with two wires only color white and black. On to extend, off to retract. Once located easy to change.
Now don't think press switch is involved.

I have the same MH model and year. Had same problem and have posted about it on here. Do a search and you should find it. There is a recall on the wiring harness. To get the jacks to work until you can get the harness replaced, pull the black and white 2 wire plug out of the side of the motor. Then you can cycle the motor to retract all jacks

If you search for a thread called Hydraulic horrors dtd. 5/8/12 posts 1-11 all history and repair are outlined with photos of the failed parts are displayed. It was complex then but others have had the same problem.

Thanks all for your help. It may be a few days before I can get to it. But Thanks all the same.

I have a 2014 351. I can't find that previous post about the jacks recall. Can someone post a link or something if they find it?

[Starboard]

It's the wiring harness, there's a recall. You need to contact LCI and they'll tell you how to manually raise them and then will ship you a new harness. Takes 30 mins to replace it, it's not really a big deal.
