Auto-zone did a test on my battery and told me my alternator wasn't working. So it drains my battery. I took it off and took it in to get it tested through their machine and it was good. I checked all the wiring so I don't know why my alternator wont work. Someone suggested it could be the computer. Any ideas?

First, forget about the computer.

The big fat wire behind the alternator should hsve 12 volts all the time

the little connector has a 12 volt hot wire and one from the ignition switch.
