Hi Javier,
What kind of electrical system do you have? 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).
Good luck,
Scott
