So if I get an HO alternator how does it charge more if it controled by the computer?Yes.
Now for a little info. That alternator's output is limited by the vehicle's computer regardless of alternator rating. I haven't studied up too much on it, but you might have to have your computer reprogrammed for more alt output or to use an AD244 alt. The AD244 is preferred since the regulator and diodes are outside of the case for easier serviceability.
