Message: <blockquote data-quote="cam2s" data-source="post: 196752" data-attributes="member: 999">End of BrushThe end appears to be rounded and making full contact with the commutator.  I will get a commutator stick and clean the black off, but does anybody have any clue how or why the commutator turned black in the first place. If there is an underlying problem, I'd like to try and fix it now so I don't damage the motor.  Thanks for your helpCameron[ATTACH=full]45872[/ATTACH]</blockquote>
