Had to take my rig in for recall work Dec 4 in Minnesota. Temps were below freezing (~28 F). Hooked up to my TV, then, as usual, hit "Retract All" on the Level-Up control panel. Rear and Front jacks were down, and all jacks started retracting -- except the front left jack.
The "Retract All" operation completed and notified me that all jacks were up. But the front left jack was still down. I switched to Manual mode and tried to retract the Left jack(s). Retracted a bit, then the solenoid clicked off. Powered the Level-up controller off and on, switched to Manual, and hit retract Left. Retracted a bit, then the solenoid clicked off. Repeated this sequence about 10 times and the jack finally retracted completely. Whew!
Got the rig to the dealer where I dropped it. All jacks extended just fine when I dropped the rig for service.
Service completed, and I picked up the rig today. Temp was around 26 degrees F. As I was hooking up, all jacks retracted except the front left. Tried the same trick of switching to Manual mode and retracting Left. That didn't work, but using a "power off/on/Manual/retract Front" sequence did. Again repeating this sequence, in each iteration, the jack retracted an inch or so, then the solenoid clicked off and retraction stopped. Repeating the sequence enough times resulted in a fully retracted jack. When I got the rig back to storage, all jacks extended just fine.
My batteries are Lithium, so I had discharged them to around 40% SOC for winter storage. That's what they were when I picked up the rig for service. I left the batteries connected and the solar active during the 1-day service visit. I was hoping the solar would recharge the batteries some during the service visit, but it was so cold the battery BMS's prevented the solar from charging -- so when I picked up the rig and tried to retract the jacks, the batteries were at 30% SOC. Even so, I don't think the problem retracting is battery related. My battery monitor is showing 12.8 V @ 30% SOC.
The LCI manual for Level-Up (https://lci-support-doc.s3.amazonaws...cd-0001531.pdf) shows a pressure switch and a retract valve block that controls both middle and front jacks. The middle jack seemed to operate just fine, so I don't think it makes sense to suspect either of those components. It's also odd that the front left jack extends normally. It's just a problem retracting.
BTW: plenty of hydraulic fluid.
I'm not making much sense of the wiring diagram in the LCI manual. It doesn't appear to me that there are separate solenoids for each jack - but in my case, the solenoid only trips off for the front left jack when I retract.
Any ideas?
