Alarm 57 on Mod #1 indicates a broken mast wire detected.
the wire that runs through the middle of the dual hyd hoses running through the mast is where the problem is.
Start at the beginning where the connector is inside the hood and goto the connector at the base of the carriage, ohm out that section, if no problem found there then start at that connector at the base of the carriage and ohm out the harness going to the manifold (solenoid block) on the top of the carriage.

you will most likely find a broken or cut wire somewhere in that area. if the harness is not fastened down correctly it can get in the way and get cut or rubbed and damage wires. If by chance you find a broken wire inside the long section running through the mast you will have to replace the harness in the mast, you cannot repair those wires without pulling the harness out of the sheath its held in, if your going that far you might as well get a new harness assy.
