Working on my 1970 3400 with the Lucas generator. After troubleshooting, I found one of the commutator brushes not touching the commutator. (pivot point dirty and not moving freely) The wire was also pinched under the cover and it broke when I removed the cover. I found new brushes on EBay and they should be here next Monday. So my question is, should I just install the new brushes and let them wear into the commutator or grind them closer to the correct angle??
Notice in photo one brush is shorter than the other.
