battery/alternator question

My 98 Integra's battery had a diagnostic done and it said that the voltage was good but it was only drawing 3A where it was supposed to be at 80A. The car place said I needed to replace my alternator. Anyone else have this happen? Is there something else wrong with my battery or is it the alternator?

yeah, pretty sure it's the alternator. just took in my sister's stang for the same reason. they took out the old alternator and swapped it for a good one.
