I own the Lionel JLC 6-18372 GG-1. It has developed a problem that I am trying to diagnose. The engine shorts out the transformer when attempting to move in one direction. If I start it up, and only go forward, all works fine. Sounds, smoke, couplers, speed control all work. When I change direction and go to the first speed step, the lights in the GG-1 dim, and the transformer starts reading a short. Changing the direction or stoping the engine, stops the short and GG-1 is then OK. Is this an indication of the Odyssey motor driver board or the r2lc?
I do not have another r2lc rev 13 board to try. My other tmcc engines have odyssey but they have r2lc ver 8 boards. Can I try and swap the r2lc with an earlier version to see if thats it? Or based on whats its doing is it the odyssey board?
