Apparently some restorers connect a Si rectifier diode across the selenium one without disconnecting the selenium. I even saw that in a book about radio restoration. It isn't a good idea because the old rectifier can leak reverse current.Since your generator had been re-capped I thought that might be the case.

It has no silicone diode going across the selenium in this unit, its just the selenium rectifier.

I definitely double checked the Selenium Rectifier and it definitely doesn't have a Silicone Diode across it, so it was done correctly!
