Automatic reverse loop module

[RailCop]

Tetters, you pose a good question. I did look carefully for a short but found nothing. What I did do was remove the reverse loop unit and reinstall it again. PLUS, I relocated the power leads. Since this was a temporary set up while I was installing more track, I use two alligator clips to attach the leads to the two rails. I later moved the leads from the two rails to the power bus line under the layout. Now the reverse loop module works fine. I have no reason for this but it works and I'm not messing with it. The rails and the bus are all connected, they are one. Yet when the power was attached to the rails the module failed. With the power attached to the bus it works. Go figure.
