Generator off a 630 Deere pos ground quit charging. It's a rebuilt from Deere I put on maybe 7 years ago or more. It will motor but it will not charge with the field grounded. I ran a ground jumper from the regulator frame to a good ground on the tractor frame and I ran a ground from the genny frame to good tractor frame ground but that didn't change anything. I pulled off the end cap and this is what I saw. It's not very clear, the top bar on the commutator has a burned spot in the middle. The brushes have not been making good contact across the commutator. All in all there is not a lot of wear but it looks to me like the rebuild job was done pretty fast and incomplete. Is this genny junk or is there some salvation in it? I could turn the commutator in a lathe to true it up but I don't think that will help me out.
