Default GM internal regulator alternator schematic

I am in search of an internally regulated alternator schematic. Anybody have one? Know where to find one?

Reason is to try and understand, at the component level, why you can use the gen light to excite the alternator. Also, why sometimes you need to place a diode in line with the excitation wire to not allow run-on. Yes, I can read a million threads on the internet about how to wire it, but not many people can explain why (from the regulator stand point)......

Scott, I emailed you schematics for a 10 SI series I got from an old Chilton manual.

Bill,

Thanks so much!! I never thought to look in an old Chilton. I bought a 1972 Chilton off of Ebay, an exact copy of the one my father has. Will check that one out as well.

Great for the OP to want to actually know rather than just following directions. This can lead to TMI and trouble later but its great regardless.

Old manuals are great. When I find them at the swap meet cheap, I buy them regardless. Who knows? I have one for Jeeps I'm wondering about but Jeeps are cool, right?

No kidding... I've got a stack (2 piles, 3 feet high) of Chilton, Motor, or OEM manuals from the 50's to the 80's. They are a huge resource of info, back from the day when people actually fixed things, instead of amputating at the largest sub-assembly and replacing.
