The BC generator is a self exciting, self regulating, brushless type unit. These three features help make the
BC a basic unit to understand and troubleshoot. Frequency and voltage output depends directly on the en-
gine/generator speed. Therefore, proper adjustment and maintenance of the belt-driven governor on
gasoline models and internal governor action on diesel models is of prime importance.
