I am working on a 60PW-S, serial 6A110734. I am having a hard time finding information on this drive system. Crown came up with a parts brake down that calls it a Model 50. it has three control cards in it. one is a GE truc tronic IC4484A191. the second is a GE catalog number IC4484B404, and the third is a GE catalog number IC4484A316. I really need a wire schematic for this truck but ant information would be helpful.
