My generator guy from St. Paul, MN picks up these Bosch regulators cheap . . . then tests them and gets them adjusted to a good 13.2 volts. The solid state regulators always puke on me.
I really dig vintage electrical components.
Mechanical over Solid State any day !
Chains over belts.
Grease over hairspray.
Linkerts over EFI . . . etc etc etc.
