Well, out of my own stupidity, I fried the motor in my LCI hydraulic leveling system. I ran it too long on "Low Voltage" and reset the breaker too many times in an attempt to get the coach level. After trying multiple shops, nobody would rebuild the motor, so I bit the bullet and ordered a brand new one. It arrived last week and I installed it with no problems whatsoever.
I used manual mode, and the motor sounded great, the coach leveled with ease. Problem fixed, right? Wrong.
When I pressed "Retract all Jacks", they continued to extend. After taking everything apart, putting it back together, cleaning all the connections etc.. they still wouldn't retract.
I knew it was time to consult the forum, and I found this thread from 2012: Hydraulic Horrors!
According to the thread, I fried a diode in the wiring harness that controls the extend/retract function of the levelers. I would have never figured this out of my own. $142 later, I'm back to 100% functionality again.
Thanks, once again, for such a wealth of information and saving my ***** for the 1,000th time.
