You will this noise about 580 is just that noise ! I can remember my first car having 30 amp Generator, and those were the days when a valve radio was fitted ! Here we have a 48 amp Alternator @ 12 Volts , or 42 amp @ 14 volts . Have a look at some car specs and you'll find this alternator is as powerful.
