[Ok, I was not aware that there was a "clutch" in the alternator that "suddenly" recognized amp draw and super engaged the alt? Come on guys. I turn on my lights and my IPFs and my RPMs stay the same. ]


Its not a clutch friend, its the magnetic resistance between the fields in the alternator. Take the belt of your alternator, spin it, almost no resistance, the field is of. But nevertheless it takes up to 2 HP under load, and yes this DOES change depending on amps drawn, simple physics... I admit I have not tried turning the lights on and of with a 2F driving the alternator, I do not have a 2F, but you can se the difference clearly in a small engine, like a 1.6L corolla...
I have a 220V 800A transportable generator, when I hook that up to my anglegr4inder it almost stalls when I switch the grinder on, and no "clutch" there
