Wow, what a mess.

I can't wait for you to share what you learn.
It may help me when i take care of mine.

BTW, a little something about motor's brushes that i found interesting and thought to share (just in case)

"...Now, "wear" is a very subjective term when related to motor brushes. In fact, "wear" often improves a motor's performance in strategic ways. Going back to the spinning globe and erasers, the rectangular erasers against the spinning globe do not ideally conform to the globe. However, imagine holding the erasers on the spinning globe long enough that the erasers wore to conform to the globe's surface - then contact is optimized. In this way, initial brush wear - or, break-in - is used by some motor manufacturers to optimize motors in the production process - that is, new motors are run for several hours to "set" the brushes. Further, most well-used powerchairs run quieter in the more-commonly traveled forward direction than in reverse because the brushes wear optimally in the most traveled direction (in a quiet setting, try driving your powerchair forward, then reverse, over some distance - the change in pitch that you'll likely hear is the orientation of brush wear)."
