Sort of genny we have on SVs is 3 phase permanent magnet type, aye?
So, this generator is a bit of a daft lump, it puts out a voltage based on what rpm it's spinning at. It charges at full whack all the time. It's not like the old GSXR's or a car with a separate field coil to control voltage.
Thus, since it's always charging at full capacity for that rpm, it physically cannot overcharge anything.
Simply, if your charging voltage is too high, the regulator has failed and that is that. No other part of the system has any part in keeping the voltage down. (voltage too low is another matter)
If you have a different understanding of charging systems I'd be glad to hear it and revise my own ideas.

If the reg rec isnt working properly and not regulating the voltage properly it can fry itself. I wasnt relating it to any other part of the system other than to suggest checking the genny as part of the fixing it process is a good idea. Im not the techy person, Steve is but this is my bare bones explantion of it that doesnt confuse a customer that often doesnt even know what a reg/rec is let alone the fact their bike has one.
