ROGER1 posted:I just tested the commutator with a multimeter. Between 2 of the plates, I get close to 2 ohms. The other two combinations yield a value of 17 ohms. Do I have a bad armature?
This is a pullmor motor ? I am not familiar with the motor on the 263e however reading resistance on a big stack pullmor from a Hudson through the brushes it reads about 2.2 ohms the field reads 1.1 ohms since they run in series the static resistance of the motor would be around 3.3 ohms. Try this, connect one end of the field to one of the brush wires or to the brush guide. Now connect a wire from a transformer to the other end of the field. Then set the transformer to 9-10V then touch the second wire to the second brush guide. Let us know what happens. if the field and armature are good and the brushes are clean and sliding freely in the guides the motor should run. Something I was unclear about in your description was it sounded like the spring was between the commutator and the carbon brush. I'm sure you know that is not correct. I often wish this site had a sketch pad. j
