Hello I was able to get my EB1's setup and working. The track isolation took a little work and I had to replace some pieces of track the Dremel tools cut the rails no problem but on small pieces of track it tore it off the ties.
Since I had to replace the track I used isolated rail joiners. couple of the larger sections of track worked well.
The EB1 that was shorting or open was a wiring problem. I had to flip the two wires on the buss line at the EB1 connection polarity was wrong.
