slelenium rectifier for battery charging on an pre 70's Vespa at a guess....
Hi John, you’ve resurrected this game once more after a 5 year hiatus. I know what this is. It’s not a part though, its a technical drawing. Am I right? Am I right?
6volt Selenium Rectifier correct!
Positive earth battery models 1946 to 1955-ish and correct technical drawing (page 89 electrical systems - The Cassel Book of the Vespa 1951 to 60 Sydney F Page)
- the only person I know with this as a physically working part of their (douglas) Vespa is Marcellinus Blanks. Selenium a rare earth element, used within recifier highly susceptible to heat, cold and time - and old parts go expensive at £180+ Used
so your both right! Next over to you
