I found my book and it shows the wiring different than shown above. It's a GM service book, very detailed. I just don't have the scanner hooked up to get the info to you.

I have gone to dealerships and had them print off stuff for me as well.

Maybe figured this one out it seems the alternator turn on comes from the computer. If the computer is not working then that is why only battery voltage. When I bought the turn I remember checking for codes and it would only give me "12" some maybe to computer died.
