As my seven came closer to being on the road over the past few years I had a choice of what to do with charging. The car was built with a dynamo to power up few lights, and low wattage headlights, in a world without traffic jams and stop/start everywhere. I considered the Dynamator, but it seemed a lot of money for something of unknown reliability.
I chose to put higher resistance field coils in the dynamo, do away with the third brush, and use diodes out of an old alternator in place of the cut out. Fitted a 12 volt battery and everything works. I intend to fit an electronic regulator, but at the moment I regulate manually feeding the field coils through a couple of switched bulbs. It works.
