Guys, the R2LC boards are getting old. They are short money and not worth wasting time to repair them. A call to Lionel and you will have a new one in three days or so. I use new R2LC boards often doing repairs. If you want to repair one for yourself, follow the outline John has conversed about. A bad R2LC board is very easy to diagnose. I pull the board and throw it in my Lionel board tester. If bad, it goes into the bad board box and I throw a new R2LC in the tester and program it for the engine it is headed for.
Many months before going to Lionel School, I was handed a package with the pin outs of Every Lionel board being used and told I had to learn them before going to school. I did so over the summer and it has paid off great doing repairs knowing where every pin goes.
I was always a fan of TMCC but am currently a huge fan of Legacy and the newer RCMC board that took the place of the original Legacy modular boards. Follow what the guys in this post pointed out to you and you will be able to get the job done.
