OK, so i just brought home a '47 series 62 sedan all original. It's basically a very nice car. Anyway, got home and the charging system seems to be have gone awry. All of a sudden the ammeter is all discharge with the lights, on at any RPM, and small discharge with the lights off. Geesh I know there are a ton of things that this could be but where does one start? Brushes, regulator, all of the above, etc? I put a 6 volt alternator on my '50 Buick with great results. I guess I should start thinking about the same for the Caddy? Gary
