Marx Universal Motor

You are talking about the armature windings, correct? The stator windings are the field.

There are so many of these motors around that it would be worth your time to just get another one.

I am talking about the stator field windings. I just got this Marx 999 from Ebay and think the previous owner tried to change the field windings for whatever reason. I don't believe that it has the original windings due to the copper color, the splice and over heating. I'm not even sure it's wired correctly. I've been searching for a wiring diagram in hopes that it is connected to the E-unit wrong and causing the over heating problem. I have another armature one has the plastic bushing and this one is brass. Both have the black enamel coating and test the same. It's the field windings that look strange.

If you are seriously concerned about it, just rewind it as a forward only engine. I have done this to a few engines just for the purpose of consistent operation.

I managed to rewind the Stator, had to completely disassemble the motor. Used 28AWG magnet wire and 32 turns per layer with 3 layers. This gave me 1.2 Ohms that matches one of the factory stators. It can pull 5 cars with the 999 body on it without slowing down and overheating. I'll put the E-unit back on it when i figure out how it works.
