I bought a Bachmann heavy mountain off of ebay a few months ago, and I've been detailing it. It has a factory Tsunami decoder in it. For some reason, the motor would stop spinning but the decoder would still make noise. I've seen some people mention that the Bachmann PCB's can be a problem, so I decided to remove it and direct solder a plug in its place. The engine runs just fine now, but the decoder gets really hot to the touch. I checked and the drive gear isn't bound. Is there more than just filtering and directional lighting to that board? If not, I'm not sure where to check for a problem next.
