LCI Level-Up Schematics?

[Minidb]

I'm digging into a problem with our 2015 Itasca Sunstar 36Y with a Lippert level-up leveling system.
The problem we're having is blowing the main 125A fuse on retract. It will level fine and will retract fine but once all the jacks are up, the pump continues to run and stonewalls which eventually blows the main fuse.
My thought is that whatever the final step is in the sequence isn't working.
Best guess is the 2150psi pressure switch but I can't tell exactly what it's purpose is. Obviously its a shut-off but I'm not sure if it's a control or a High/Over pressure cut-off.

I'm looking for an electrical schematic if anyone has one. I couldn't find one on LCI site and haven't got any response from the couple of emails I've sent them.

Appreciate any help or suggestions

Have you tried to call LCI? They were very helpful to me on the telephone about a different issue.

I've sent the tech department a couple of emails requesting the schematics but no response.
I did call them when we first had the problem and we're in the middle of Nowhere, Nevada. They helped us out with some checks but their fix was to replace the pump for $1000! We were on our way home so just altered our setup by manually shutting the pump off until we got home.
I'll try an old school phone call to them next!

On my Winebago Vista, the LCI Leveling System Positive (+) Power Cable from the motor solenoid lands on a ANL fuse in the Chassis Electrical Box that is tied to the Chassis Battery Disconnect Solenoid. It is a #2 gauge wire. Not sure what size fuse, likely 80 or 100 amp.

On my Vista, the connection is behind the circuit breaker panel. IMHO it would be a lot easier to disconnect the Negative (-) cable from the solenoid on the LCI leveling system pump if you are dealing with a solenoid stuck in the on position. The solenoid appears to be removable and replaceable, it has a LCI part #on the Level Up manual.

If I remember correctly the 2150 pressure switch shuts off the pump when jacks are raised and you get a jacks down alarm if it falls below below 1200 psi or close to that. It has been a while since I looked at mine but If I remember that switch is what lets the controller know to shut down the pump when retracting.

Thanks, I'll check the solenoids to make sure they're fuctional and I'm going to pull the pressure switch and get it checked at a local hydraulic shop. At the same time I'll put in a pressure gauge so I can monitor the pressure during retract.
All that will happen once it warms up a bit, still winter here in NE BC!

I’m having the exact same issue with our 2015 Winnebago Vista 36Y. Did you ever come up with the cause and solution? Thanks.

Sadly, I've gotten as far as purchasing a new 2150 pressure switch. Life threw us a few curves the last couple of years and I haven't been able to make time to install it.
I spent a lot of years maintaining mining and oil field equipment and I'm 90% certain that it's the cutoff switch.
The pump is good because it levels fine and only blows the fuse on retract so it's an over pressure situation. It could be contamination in the fluid blocking the switch but with a closed system I think that's unlikely.
The switch is a relatively simple swap out and at less than $200cdn I figured it's a good first step without taking it into a shop for diagnostics
Good luck!

Sounds good. Thank for the update. And good luck to you as well.
