I'm stumped. Had it all apart. Everything looks good. Cleaned the brushes and commutator. The magnets for stator were ok and I cleaned them. They would cause a little resistance when I turned the rotor. When apart I still have 12 volts at the brushes. When apart I have continuity between all 10 segments of the commutator and there is no short with the metal part of the rotor or main shaft. When I put it together it doesn't want to spin even when I help it.
Nothing interferring with the brushes. With power disconnected I get continuity with about 7 ohms and it fluctuates when I turn the rotor which tells me the brushes are making contact ok.
Just like before I have 12 volts everywhere until I turn on the switch and it goes to 0 but nothing sparks. When I had it apart and getting 12 volts onto the brushes, the switch worked fine so the power circuit seems good until I slike the end cap and brushes onto the commutator.
