Not exactly...but the one I'm working on will be for only 20 amps, mostly for our antique tractors. The problem is when the regulator is mounted ON the generator itself the intense underhood heat from the exaust manifold and radiator heat the regulator to the point it changes the settings, so much so that after a good hour of running it will not charge anymore. If you relocate the regulator somewhere else on the tractor they work pretty well, but most people want the tractor to remain "stock" looking. I have a 30 amp diode which is only a little bigger than a nickle, I'm not sure how much heat would have to be dissipated....cant see that being too big of a problem though unless one pulled 30 amps for a great length of time. If that does become a problem my next plan was to use the originall reverse current relay and make the voltage / current regulation solid state, all neatly under the originall lid.
