   But THAT'S why I'm asking here: this Denso alternator (used in MANY Hondas,   
   Toyotas, and myriad other makes) does have a common terminal connection to   
   the rectifier. The rectifier has EIGHT diodes.   
      
   Yes I agree that common configuration is 6 diodes. That's why I'm confused.   
   The system is quite populous and apparently functions. I just don't   
   understand how.
