*Sigh*
Okay, I've checked the leads again, and noticed something bizarre. When setting my multimeter to checking resistance, the ohms went up when touching both the AC hot lead and the center rail, but also went up when touching the hot lead with the outside ground rails.
Second, when checking resistance to the blue wires to the second motor brush, it didn't respond...until I touched the outside of the can motor instead.
Third, the red wires responded to resistance on both the first and second motor brushes.
I'm not sure what it is about this engine that makes upgrading it so tedious, but it's starting to get on my nerves. I don't get it. Has anyone else upgraded these engines to Command, and if so, have you run into these problems? I'm considering upgrading similar Lionel steamers from the 90's, and I really hope I won't run into these things again.
