Brushes, and the burnt side
I've been browsing this forum for some time now and I've learned alot; however, I can't seem to find a question I've been having. My question is I've aligned my brushes and still have black on 1/4 of the trailing edge are my brushes not aligned still? I've heard that that blackness on the trailing edge is always there on a stock moter, but I've read that it should dissapear if the brushes are aligned propperly. Anyway suggestions?? Should I realign the brushes or just leave it and run the moter? I've aligned them after cutting the comm and made sure that the break in mark is in the center of the bruch. Can someone help me with this. It would be greatly appreciated.
