I have a 401 car with generator drive that intermittently ends up in the pit, it usually happens about once a month, but got progressively worse, about once a week. I swapped out the transducer i/o board and general i/o board with another car and the problem went away for about 2 months. now it is back and happening once a week or so, any ideas. other than this problem the car runs fine and does not have any other breakdowns, it is never occupied, and seems to happen sometime at night, as we get the call in the am.
