The 6V Volkswagen regulator Borg Warner R580, Biehoff WA702, Bosch 30020
What's what on the VW regulator? The picture tells all! These regulators are the way to go with a 6V Chang. Try to get your hands on a name brand like Bosch. Many thanks to Steve Christo and Richard Cook for helping me figure this out.
If you're fortunate enough to have a Bosch 6V VW regulator on your bike, you'll want to read this page about making adjustments, etc., courtesy of Steve Christo.
