That was the first thing I checked out, they turn a little but they appear to be fine. One thing I forgot to mention is that when it stopped working I pulled the switch a few times and on the fourth time it made a couple turns, not enough to get to full speed and then stopped. Last time I could get the PTO to work. So far everything is checking out except that the tractor starts if the parking brake is on or not. I know the PTO won't turn if the parking break is on. The schematics I got from the dealership are junk and don't show the relationship between the curcuits. Trying to figure out if that is the problem or not right now. Also there is a red and green light on the board. Do you know what they are for?
