Charging system output??

[Churchkey]

Don't have a service manual yet so----

Can anyone tell me how many watts the charging system will deliver on a '04 Busa?

TIA

600-650 watts ... but the peak charging range 13.5 to 15.1 volts doesn't occur till 5000 rpm

Do a search and you can download the manual on pdf from this site for free!

Thanks Guys, 'preciate it.

You get plenty of volts from the system at anything above 2000 RPM, but I think Dez is right that it does not charge the battery until 5000

Here are the voltages I recorded last year when I was trying to figre out if my alternator or the battery was my problem.
1000 - 12.5
2000 - 14.2
3000 - 14.3
4000 - 14.2
5000 - 14.2
