Hi all, looking for some help confirming what I believe to be a bad R2LC board. My 3rd Rail B&M R-1a Mountain won’t respond to tmcc commands or take programming. Engine sounds start up when power is applied to the track. Runs great in conventional when I disconnect TMCC, won’t run in conventional with TMCC connected, so it must be picking up the signal. I reseated the R2LC but same problem. I don’t have an item number for it, but it’s number 4100 from the 2005 catalog. Here’s a picture of the R2LC. The last time few times I’ve run this engine it had to be reprogrammed each time.
Any help is greatly appreciated
