The commutator can be ohm-metered out: Opposite lamels, pair by pair, should be quite even readings. If your machine runs slow and unsteady with a murmur and cat-piss like smell, some winding may be smoking. That can be in the field winding too.

Repairing a burnt winding perhaps isn't a job to be done at home. It takes some motor knowledge, expertise, tools, and nerve, as well as a place where you can bake the lacquer on the new winding without ruining marital bliss.
