Default Alternator turn-on voltage

Hey guys,
I'm finishing A&A supercharger kit install on my 2002 zo-6 and notice the alternator is not charging.(11.5 volts) everything hooked up tight and turn-on voltage 5/6 volts, output on the back of the alternator 3/4 volts.

Thinking I have a bad alternator. I not sure any codes, I'm just looking into now. Car has 70k miles(I believe original alternator). Y'all agree?
