Thanks for the photo and clarification, John--I really appreciate it. The loco I'm repairing (Blue Comet) is "ancient" as a lot of you guys would say--around 1998. I'm pretty sure this was the first scale Blue Comet MTH made, so I assume it's PS1. It has spent most of its life in the box, so no electronic updates have been done on it. Before I break out the soldering iron, I'll make sure I have clockwise rotation and solder the wires accordingly.
Here's the diagram that indicates counterclockwise rotation is needed. Seeing how air is supposed to flow out of the housing, clockwise makes much more sense, but thought you'd want to see this anyway.
Thanks again
John
