alternator problem - done searches.

ok guys, i've had this problem before and i've read the forums and i've actually been a starter of a thread like this a few years back. Here's my problem.

I JUST got a new alternator today, bench tested at autozone and checked working. Producing 14v after putting on load.

I installed the alternator today and have a new optimum red top battery.

I installed the ground on the alternator, the positive, and the 2 prong connector that connects to the alternator.

After firing up the car, i tested the voltage on the battery. it was 12.35 when the car was off and 12.15 when the car was on. I disconnected the Positive cable from the battery and the car died almost immediately. At this point, i figure something has to be wrong with my alternator, BUT i just got it bench tested a few hours ago.

I disconnect the positive cable from my alternator and test to see the voltage produced by my alternator free of the battery. It produced no voltage.

My question now is what does the 2 prong connector that plugs into the alternator do? I don't have access to an FSM so if anyone could possibly look this up for me i'd appreciate it. If this 2 prong connector is malfunctioning, could if cause my alternator to produce 0 volts?

I disconnected the 2 prong connector and the alternator still produced 0 volts.

Please help me, i've checked my fuses, and checked my grounds, i can't figure out what the problem is.

Thanks!
