Default Horsepower to spin alternator?
Has anyone seen any tests on how much horsepower it takes to spin a loaded alternator?
Reason I'm asking is I have seen test done where it takes 15-30hp to spin a manual cooling fan (depending on type). So everyone says go electric. But with the added demand of the electric fans and most likely larger alternator, how much hp is really freed up??
