The original Russian generator or an alternator conversion? What you are describing sounds very much like a voltage regulator failure (or a failure of connectors if your alternator conversion was wired with connectors...) IF you have an alternator conversion. I am unfamiliar with the original generator set up, so I can't speak to that (although there are folks on this list who can...). IF you have a B&C alternator conversion, go to the B&C website and download their instructions on troubleshooting the alternator/voltage regulator (http://www.bandc.biz/downloads-reference.aspx#S1).
