This is more to understand what might be wrong rather than trying to fix it as I have a feeling it's beyond repair and it was free so I lose nothing.
What it happening is it sounds like a motor that has it's centrifugal switch stuck and is trying to run off the start capacitor. The thing is it has neither of the two items. I did notice the case was warm to the touch after just a few seconds which would lead me to believe maybe someone overworked it and the insulation is breaking down on the windings, but obviously I could be wrong. It doesn't have any sort of "soft start" like some better grinders do so that is not an issue.
The bearings feel good, but I also know that doesn't mean squat so maybe I missed something there since there is a big difference between running my finger over them and putting a load on them.
The cord goes in to the switch and the line side goes to the first brush. On the other side the brush is connected to the outer windings. Back on the first side the outer windings are connected to the switch and finally to the neutral side of the plug.
