Sometime this week I am going to look at an intermittent issue a fellow tech ia having with a 200fpm car. It shuts down after a few weeks of running fine. Errors are first and second speed boards. He has changed both boards and replaced the bifurcate relays and it still does it. Never been one to think about it before I get there but the building is not a pleasant one to go into. Looking for a lead before I get there.
