Update: I removed the pantograph motor that was not responding. I then put 9v DC to the motor and it started right up. I then connected the powered unit and non powered unit on my layout, powered the track and once I aligned the tether, all the motors responded appropriately. I'm thinking some advice GunrunnerJohn gave me about motors in smoke units...sometimes they hit a dead spot and once you manually nudge them, they start working again. That's what I'm thinking here. Of course, I sent one of those little screws that hold the motor to the shell into the next dimension, at least I hope so and it's not waiting to fall out of 'somewhere' on the 4th pass around the loop and short everything out... I'm going to look for a replacement screw....
