I have a Lionel 1946 2020. This is the "A" variation with he smoke bulb, red "6200", and internal E unit (plugs on Atomic Motor brush plate). When I apply power, the e-unit engages (although not well), but the motor itself doesn't respond. I've tried putting power directly to the motor and still nothing.
I am guessing that an internal wire is broken somewhere but I can't see anything. I have a meter but I'm not sure where to check for continuity to try and determine where the problem is. Can anyone help me with this?
Interestingly, the smoke bulb still works, although I had to basically chisel out the smoke residue all around the front of the engine.
Thanks for any help.
