Got a L228 in last week, got if off the trailer, around the yard some, in the shop for clean up. Code 4754 came up after it got back outside, swash plate sensor, loader wouldnt dive, finally got it to drive back into the shop, got the codes to stop popping up, but now the boom wont come down. can hear the pump working trying to go up, and the tilts work, dont hear nothing trying to go down. What might it be? pilot controls if that matters. Thank you
