John Deere 328 Ser # T00328A101821 Friends machine that I helped him a few times fixing hoses and o-rings. Today he changed a pipe from the boom that had a leak. Now the machine has forward reverse, but no boom up or down, No bucket curl either way. Think it is maybe a safety circuit problem with no power to a solenoid. Does any one have a schematic that tells which fuse feeds the solenoid and what safety switches are involved in the boom up function. I understand that on door machines the safety switches prevent you from ripping off door while booming up with switch contacts not closed probably, don't have schematic. He changed the pipe, topped up oil, drove out of shop and back in once he found out he had no boom up or curl. Any help appreciated. Simon C
So the boom and bucket handles are locked (can't move the spools)? After sitting in the seat and putting on the seat belt, releasing the park brake, are any lights remaining on in the instrument cluster? Which tube was replaced? If it was a tube at the control valve, was one of the solenoids unplugged and got missed on reassembly?
He just informed me that the boom and bucket handles do move . Did ask him all the pertinent questions. He is going to check on the dash lights, and check all the fuses. Will get back with what was found. Thanks for the help. Simon C
So friend cleaned the connection at solenoid, Checked and replaced 1 damaged fuse and now it runs, and boom lifts. Will see if it is cured in next few days. Thanks mg2361 for a little insight. Simon C
