Bobbyd, Yes, had an Atlas Erie FM AB, both powered and as train #7, running on an adjacent track at the same time. And, had been running the F3 ABA just prior to the strange behavior. No kidding, the "clank" from the powered A unit and the return of F-N-R-N-F sequence, with only ERR electronics installed (with exception of original MTH lighting boards in both A units), that is most puzzling and almost of more concern than loss of RS. No doubt there was a "clank" from the power unit, heard it too many times to be mistaken, still couldn't believe what I was hearing. Plus, the fact I ran the consist in this state, power on/power off repeatedly and let it sit for as much as a minute, for close to 30 minutes trying to figure it out. The power A unit was ran separately when going through reset of the engine ID and feature #6. It did return to comm control, but no RS. Still scratching my head over this, and with some loss of hair! LOL!!
One other thing, before this behavior, the rear headlight(in dummy A unit) did not light in reverse but the rear couplers work fine. Now, after the strange behavior, the rear couplers still work fine, but now the rear headlight works every time. I had inspected wiring many times over the years and it was wired correctly, but rear headlight did not function until now. This, even though the Mars light has always functioned, and no, as you can see in pictures, I do not have the front coupler wired to function.
