If I did this correctly, second set of tests were also good:
"After that, keep the paper there so the brushes don't connect but touch the commutator with one probe and the steel on the armature with the other. Do as O_D mentions and check each segment of the commutator to armature steel. The meter should not move ie no connection or infinity."
Put one probe on commutator segment and the other and the armature steel directly below it. I got a couple of "short" readings, but realized the motor had moved and was hitting the electromagnet frame. Once I kept them from touching, no shorts.
I also connected a probe to each commutator and to the shaft. Not sure if that tells anything, but no shorts either.
