Did you make sure everything is wired up correctly and you dont have a blown alternator fuse?

We've had plenty of remanned alterantors junk out of the box, so don't forget to consider that avenue as well. There really isn't much else in the system that won't allow it to charge it fully.

edit: Is the battery itself in good condition?

I just bought the battery a couple weeks ago so i doubt that is bad but i guess i could run it up to auto zone and have them test it

Check your belt too.

You can test out your alt.

Start the car. Get a vom then check the voltage from the battery, should read about 14v, If its lower than 12v that alt is dead.
