I had the same problem turned out the back bearing was locked up and was spining in the housing. after ovehaul new bearings new brushes I used a drill wrapped the gear to the drill with duck tape hooked up to an volt meter and the generator to a battery and spun it up the result was 14.5 volts which is good. least you know the generator works then can check the regulator.

Yesterday I noticed that when I started the plane the ammeter was not showing the charge I was used to . I revved it up and it hopped up and showed a charge. As I was flying, I began to notice it on the discharge side a bit. It went further on the discharge side when I turned something on. Obviously, not charging. I started it today and it never went into the charging area. I would like to try what I can first to find out the problem before I go the certificated (A&P) route. I am thinking that the behavior could indicate a bad regulator. Of course, the generator could be at fault, too. I presume I should be able to check generator output at the regulator to see if there is sufficient voltage? That should tell me right there... Any simple tricks are appreciated. I know we cover this from time to time, but this time it's my time! Thanks, Larry in Missouri N99340
