I've had oreillys charge the battery about three times as well as putting it on the charger at home too after it gets drained. I'm using a multimeter and testing the output from the alternator at the battery terminals with the car running. Also using the ground on the battery and putting the positive lead to the connection on the fuse box under the hood. Getting the same voltage in both places. I don't see it being a bad alternator seeing as I've had them tested, so it was a bit of a waste that I bought a new one, but, oh well.

What I'm thinking is that I'm getting some resistance in the circuit somewhere....problem is, I know jack about the wiring and need some help.
