I am a Flyer guy, but a friend asked me to look at his old Marx 666. I took it apart cleaned and lubed everything and put it back together.
Woo hoo, the chassis runs like a bear, and smokes like a chimney. That is until I put the shell back on and now I have a direct short.
Can somebody who knows these Loco's suggest what the problem could be? I am seeing metal trailing trucks, metal pilot frames, and don't really know where to start.
Thank you in advance,
