Anybody ever run a back up alt on an air cooled vw, we have and many have had issues with the stock location alternator mostly from cheap chinese parts failing, thought we could mount a secondary alt in place so when needed we can flip a belt on and have charging with out the long job of changing a vw alternator.
Rumor was the McMillians did it long ago any body got pictures?

Cars would run a 2nd unit , chassis mounted for use during race where there was a lot of night time miles. This is pre HID / LED.

I don’t recall what specific alternator was used, but it seemed to work well. I want to say they were Toyota or GM units.
