    Hey all,
    Working on a American Flyer loco with the old open frame. E unit works. Problem I have is the motor is not reacting at all to power. I even disconnected the tender, hooked up some leads to the motor and no reaction. Anything I can do other than a rip and replace? Thanks!

    Check the brushes/springs and make sure no wires have broken off the commutator. Also, check to see that the field coils are receiving current, otherwise, you will have no stationary magnet. Those are about the only things that can cause a dead motor.

    Thanks. I was thinking of pulling it out and cleaning it down with some electrical cleaner. Hasn't been ran. Seems no current is making it to the motor. Would electrical parts cleaner be a good choice?

    If it is a degreaser, yes. Otherwise, mineral spirits followed by 91% rubbing alcohol or the alcohol alone if you see it is removing dirt and grease.

    Took it apart, cleaned the plate, it reacts now. Just hums and smokes. Able to turn it with my finger but that's about it? Maybe just replace the whole motor.

    Maybe. Or clean the windings to make sure it's not shorting across old carbon deposits, and clean the brushes and commutator, especially the little troughs.

    If you used a cleaner with oil, make sure it's completely wiped off.

    Tried that. Going to soak it in electrical cleaner. Might be like you said a short. Theres a few old deposits I've tried scrubbing out but it's on there good!
