can you get a full model number and serial number? and voltage of truck?

I did some checking on a 36v truck and error 57 deals with broken wiring in the auxillary hydraulic circuit.
You'll need to check the wiring in the mast cable, also pay attention to the connector at the base of the mast where the carriage side of the main harness starts, and even go out to the pentograph and check the harness running through it out to the forks and make sure it is not smashed or damaged.
