Testing a Bridgeport 6R-A Motor Without a Control Board

Thanks for checking. I have resistance in both sets of windings, and no grounding of either one, so chances are the windings are still good. One brush came out easily, and was in perfect shape. The retaining screw in the other brush holder didn't want to unscrew, so I left it alone. Since both circuits put out voltage when you motor the armature, I believe the brushes are both making good contact.
