I have a Lionel #50 gang car. When the front bumper is pushed forward the car goes forward but when I push the bumper backward the car still goes forward. I thought the one field coil was bad but why would the car not just completely stop in that position if that was the case? I had to rewind the field coil because the wires broke off and I was unable to connect them. Any help would be greatly appreciated.

Earl J, do you have the wiring diagram from the Lionel Service Manual?. If not, email me and I will send it.
I had the same thing happen with my #60 trolley. If you can’t fix it I strongly suggest you go to ‘themotordoctorDOTcom’.

Yes, I did finally look for one and copied it.

Thank you for the input. I will look at the site.
@Überstationmeister posted:The one of the fields is wired wrong- they should be "opposite" each other in relation to the brush (armature) and ground. Wiring them the same results in the swapping of which coil is energized, but not the actual field direction.
Thank you for your help. I went to change the wiring and the wire broke again. I need to rewind the field coil again. Would you recommend using new wiring this time? How do I find the wire size?
The motor doctor rewound 2 field coils for me, and did an excellent job at what I consider a very reasonable price. I don't know the guy at all, so I'm not plugging a friend. I'll be quiet now.
The wire size for the field is 28 (0.0119). Motor winding details are found on page 47 of O-Gauge Reference Manual II, Motorized Units, Rolling Stock & Accessories by Robert A Hannon.
