I recently unboxed my Lionel TMCC only magnetic crane, which I've had for about three years but never took out of the box. I wired up the five rail track from Gargraves but when I send the commands from my TMCC controller, each motor makes noise, showing that it is getting power, but nothing moves. I get no movement out of the boom or the unit itself. Initially, it did move on the rails, but only briefly. Forum members were very helpful in getting my clamshell non-Tmcc version working and it now runs like a charm. Any help, thoughts or ideas or diagrams would be very appreciated.
