code 35 is traction throttle out of range.
check the handle. does it seem to be a bit floppy? code indicates pot voltage out of range. check the wiring on the carriage and tractor interface card. have you any previous knowledge on truck? you will have to run calibrate on unit. you will have to enter two passwords using the hour meter select button, power control select button and the up down buttons.

No replies? :'(
