Car is Completely Screwed....Need Help

It is kind of bad that I went through all these alternators but I do think there are reasons for them.

The first one was the stock one and it did last about 11 years, the second one was a stock re manufactured one and I hear about these ones screwing up all the time, the third one was a load boss at 175 amps and this alternator went through hell. When I originally put it on it did not have a good connection where the hot wire goes and it got charred there. After i fixed that problem I believe it could have been getting some water damage from the way my hood is. Then the day I made a shield for the alternator it took a crap on me. I also had my underdrive pulleys on for the last three alternators. Now with the new alternator I had the shield that I made out of sheet metal on it and it worked really good until yesterday. All of my other ones always died by not charging. This last one died by charging way too much.
