Electrical problem
1997 Saturn SC2 4 cyl Front Wheel Drive Automatic 180000 miles

Hey Guys,
I was leaving home one day and I tried to start my car, and it would not start. So I immediately pulled up my buddy's car and tried to jump start it. Well in the process of jump starting smoke appeared form the side where my alternator is located. So I pulled out my volt meter checked the voltage and I got a reading of 12. So I turned the car back on and checked it and I got a reading of about 11.32. Which is when I recognized that my car was running of the battery. So then I jacked the car up. I saw my fusible link was burned up so I replaced the fusible link and my battery, started my car and checked battery voltage and it read 12.50. Which told me I was still running of the battery. So I changed my alternator started my car, checked battery voltage and got a reading of 11.59. Which still tells me im running off the battery. So now im stuck trying to figure out why the battery is not being charged. The belt is fine, pulleys are fine, battery connections are fine, car starts fine. Im totally stumped on what to do next.

I did not get either alternators checked, but I checked all of the fuses in the main fuse box and they are all still ok.
