Default no charge after 3g swap

I got done with the swap and finally managed to jump start my car, but I checked voltage and I am only getting battery voltage which is low right now. So here's what I know, I ran the 4 gauge wire through a circuit breaker to the starter solenoid. I soldered ring connectors on the black/orange wires and hooked them up. Since I did not have a dedicated stator wire, I ran a wire off the output post back into the stator. My regulator plug could use cleaning, but I know it wouldn't prevent a charge. I am getting voltage throughout, but no charge. I'm thinking the alt may be faulty, which sucks, but what do you guys think? Just want a second opinion, thanks

If you have voltage at the exciter wire and the post on the alternator, I would take that thing back until I got a good one. I once put 6 alternators on one car before getting a good one so, yeah. Take it back.

I've heard horror stories like that before, but I figure hey they gotta replace it, better than buying used and taking a chance because it was "known" to be working. Im going to give it a shot, I hope its just that, my battery needs charged

parts are just no where near what they are from the factory. It seems like all accesory parts from parts stores are like that.
