I have been working on my layout in preparation for my grands here for the holiday. In testing the layout today, I found some strange things happening. When pressing buttons on the Cab 1 controller, sometimes the track switches would operate,. Other times they wouldn't. I tried reprogramming the SC-2 controllers I use for my switches. This helped some but I am still having problems. Sometimes a switch will operate, the next time it won't.I have never had any problems like this before. Any TMCC experts out there have any ideas?? I'm totally at a loss.
