Fall right in with the other 90% of internet techs that cant ever explain a damn thing that they say.
Think of a battery as a large capacitor. It job is to store and release energy.
It also serves as a "cushion" for the rest of the electrical system.
The job of the alt/reg is to maintain the state, or level or energy. Large swings in load are not good for the alternator, or regulator.
Batteries with very low levels of charge can ruin an alternator quickly.
Depending on several factors, disconnecting and reconnecting a battery can potentially spike the regulator.
A popular misconception is that the electrical system runs off the alternator.
This is not really accurate. the electrical system runs off the battery (remember, its a capacitor). The alternator merely maintains the state of charge in the battery.
Disconnecting a battery while the engine is running is not good practice. Its possible to get a voltage spike thats induced when the load of the battery is removed. Similar to the voltage spike when a fuel injector is turned off and the field collapses. Those voltage spikes typically measure 60 plus volts and have been known to be detrimental to injector drivers. So much so that some manufacturers have went to the extent of using clamping diodes to surpress the voltage spikes.
Sorry for the long winded. hopes this helps

I hooked the alternator up and its not putting out any charge at all.

Either the alternator is dead (I didn't get it checked before putting it on) or the connector on the back is screwed up. When pulling the old alternator out I snapped the wire and had to put a new connector in its place. The old connector only had one wire and this one had 4. I hooked up the wire that was in the same place, but I am doubting myself now.

Going to drop it down and take it to autozone for a bench test. And then go from there.

Well is what usually winds up happening when you jump it with a dead battery or disconnect the battery with the engine running is it will charge wide open and usually knock out the diodes and or regulator. You may get away with it once or twice and not see any problems. But from someone who see's this stuff day in and day out. It's like unprotected sex with a crack ***** you may get away once or twice but it'll catch you and bite ya in the ***.
