Ken, When you say nothing in conventional, the engine doesn't start up, headlights come on, basic sounds? It just sits there dead? If so I would be interested in MTHs response.
If it does startup just won't move, I would try a transformer (feature) reset and use the throttle vice direction button and see if that works. If not, use DCS to do a reset with the system, then shut power off to the track/engine. Then try it in conventional. If still no joy, last resort is a sound file reload. After that MTH needs to figure this one out. G
GGG,
When putting power to the track in conventional mode, nothing happens. no headlight, no sound, nothing. If and when I figure this out I will post
