I have a 2008 v6 pony pkg for about three years now and I have been trying to fix this problem for over a year now!
It started with my battery going dead, then a few months my alternator went out.. then a week later, the alternator again.. after my 8th one, it started working right.. for about a year. Then we come to yesterday and its doing it all over again.
My lights dim for a little bit a few times when I drive. I don't have any systems in it or anything.
The only thing that seems to pop out is the positive cable from the alt. its a little burnt from the first time all this happened.
Any one have an idea on what I can do to fix it?
I attached a pic of the cable. Let me know it doesn't work. I had to click the little box for the pic to open up

Before you just keep throwing more parts at the problem, I suggest having a tech inspect and test the electrical system. You might have a bad connection somewhere.

You may have a voltage drop in the harness. Use a volt meter and check the power from the B+ on the alternator vs at the battery. I've run a new wire from the battery directly to the B+ of the alternator on old euro cars because of a voltage drop

I agree with Nuke, get a good alternator and upgrade the battery cables and grounds. Make sure all of the connections are cleaned with a wire brush. Any corrosion will cause a voltage drop and get hot. You can check everything by running it about ten minute with the headlights on and spay a little water on the connectors, if they are hot, the water will sizzle.

Please make sure the battery is charged fully before installing your alt. If you use your Alt to fully charge a dead battery it will end up cooking it. Alternators are designed to maintain a charge in a battery, not maintain a charge and charge the battery fully at the same time. They can do it, but they will get ruined.
