As I posted on the electrical board, I sent Dale Manquen a BPC. He initally had the same problem, but got it working. He called and suggested I power the modules from a separate transformer not phased to the other five. PROBLEM SOLVED. Obviously, there is a point somewhere on the layout where the earth ground is crossed with the track common. Haven't found it yet. Dale suggests that I keep looking even though everything seems to be working with the isolated power supply.
