The rollers was the first thing that I tested. I lifted each end off of track one at a time to see if they were making contact and they were then when I had it on the bench I also check with a ohm meter both the roller to roller and wheel set to wheel set both were good.
In my life a little flicker no big deal I can live with that the engines don't miss a beat and all is good now with the CSX yard. I just like to run the trains nothing is perfect.
Thanks Again to you All
