I'm not sure who did what or when to this BS series C. I pulled off a Rita ignition system for a simpler mag. I have started digging into the wiring trying to clean it up. The dynamo cover says Miller 6 volt; however I'm finding 14 volt bulbs in the head lamp. Before I start tearing into the dynamo, has anyone heard of anyone rebuilding the Miller 6 volt and converting it over to a 12 volt? Many thanks
