Well I am not having any luck with this bastard 401 elevonic car, it continues to go in the pit. I have replaced all controller boards and power supplies. I have verified the initiation switch is working properly. the car ran 10 days before going occupied in the pit with 4 people inside. I logged on to the omt and the 200-6 test indicates the car is 00 out of service, 13 normal operation. i checked the position and it was below floor in finals at 9.2 feet. there were no abnormal conditions in the 200-4 test. just jumped out finals and car comes out of pit and back into service. The occupants were coming down and the car just went into the limits. the last things to change are the cop1 board. I could change encoder or ppt but i dont think this is problem. Greenpants, do you have any other ideas? Im going to change cop1 board with another car, but i dont think this is the problem.
