Having problem with an MTH ITAD hooked up to a crossing signal. I have one wired to the layout that is working properly with activation as the train passes the ITAD infared and stops once train passes. The other one is "constant on" and will not go off. I have taken the ITAD off and tried it on a separate layout and it works fine.
Do I have a bad connection on a piece of track somewhere??????....... Suggestions....
