Are you seriously suggesting that a 12 volt alternator is
made with a diode trio that cannot handle 24 volts? I was
under the impression that few silicon rectifiers are made
with a breakdown voltage less than 50 volts.



What PIV diodes do you think you need for 24 volts?


Need? 35 volts should be enough to work, but I would like
at least 100 volt.

What PIV diodes do you think they put in the trio?
