if i am mounting a alternator on backwards( pully pointed towards motor not away) do i need a reverse rotation alternator or do they work either way?
I think it is more a issue of the fan blade moving air properly in a reverse direction. And pushing or pulling air through something to cool it may have different effects due to things like cavitation and turbulence. If you do run your alt backwards I would just run a flow test as FABRICATOR mentioned to insure air is flowing through the alt. Excessive heat will kill any alternator!I would think a fan sucking air past/through the alternator would work about as well as one blowing at it, no?
