Hi, need a little help
Bachmann G 4-4-0 steam engine. Was running fine, then the transformer was set to "zero",but left plugged in overnite. Now the engine will not hum, light up, attempt to move , or make any noise while on the track. When drive wheels are lifted off the track and the guide wheels stay on the track the engine runs and lights up. When I set the drive wheels back down I see a blue spark off the rear drive wheel to the rail as the wheel gets very close to the rail. If I bench test by touching power leads to the guide wheels where the pickups are the engine runs. Where do I start???
