Getting oil on the commutator is destructive to a generator, not only does the oil form an insulating barrier between the copper and the brushes, but it can ultimately soak into the carbon brushes and decrease their effectiveness, reducing or stopping the generator's output. Generators (and some starters) need oiling, but not over-oiling.

Regardless of what occurred in your situation, the moral of the story is to read the lubrication charts and requirements for your car and follow their guidance.
