This is an internally regulated 12si high output alternator that’ll keep up with all the power needs of the not so Day 2 stuff we’ll be using. Currently (Ha get it, currently
) re-clocking it as these always come clocked for a passenger side mount not drivers. Already changed out the pulley for an old school deep groove. I like these alternators they have an old school look and still give plenty of juice for electric fans, fuel pumps, A/C, stereos, etc.
