I am trying to service my 322 Hudson.
I replaced the brushes and the E-unit fingers. Cleaned the commutator. Lubricated the worm gear and motor shaft bearings.
Upon applying power, the armature tries to turn but doesn't. The field gets very warm. I traced the wires. The armature and the field are connected in series. The field is switched by the E-unit. I can turn the armature freely by hand. I don't detect any binding.
Any thoughts on what to try next?
