Re: is my alternator knackered???
Good evening.
A permanent magnet alternator such as the SV's will continue to pump out increasing AC voltage the higher it spins.
I think you'll find that if all is well with the charging system after 5000 rpm the regulator will start to errrr regulate, & start to lose the excess AC voltage as heat. Therefore if the alternator is to specification at 5000 rpm it is capapble of supplying the bikes demand.
Cheers.
