I have an older MTH Railking Challenger made in 1996 that does not run. If I place it engine on track, the headlight comes, but that’s about it. This engine will not come out of neutral when I cycle the throttle. There is also no sound coming from tender speaker.
I suspect it’s an issue with the QSI reverse board. Is there a component in these early QSI boards that typically fails? Or would it be best to just replace the board, that is if I could even find one!
