What I want to do is to externally regulate the 12-volt circuit. I was thinking of using a modern solid external regulator or an old-fashioned type to control the power to a 12-volt battery directly. Controlling the rpm's is of no concern to me. I don’t care if the throttle setting is uncontrolled (other than the on-board governor). Basically, if the generator is producing too much power as the battery takes a charge, I want to wean off the electricity going to the battery. At that point, I am only wasting fuel but not cooking the battery. I can be reached directly if you wish at donparadowski@yahoo.com. Thanks.
