Are you sure it is good? Is the motor good? A lot of times the motor goes bad an then burns out a transistor on the E-Unit. New e units are about $20. G

I tested the motor with a DC transformer disconnected from the rest of the wiring. It seems to run fine. The E unit could be bad my next step is to order a new one. However what do you mean by track power? The pickups? The black wire is connected to the rollers and the green wire is currently connected to the frame of the locomotive. is that right?
