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!

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
