OK so I went ahead and ordered a bandc regulator. I spoke to them about
it. It has the same mounting holes and footprint as the ducati VR.
It has an internal OVP. If the OVP trips then you cycle the generator.
This means I'm going to remove my current OVP which I hope should not be
too much of an issue.
I also am going to take the opportunity to change my fusible link to a 25A
fuze.
thanks
