Ok I put a new battery in and every thing seemed fine for a day then more problems my volt meter would drop down and my stereo would cut in and out so I replaced my alternator today and I did the check at Kragen (on the car) and it says charghing system problem, I checked my fusible links and replaced the black one the one that seems to fry all the time. and my volt meter still says like 12 maybe 11 but my stereo and interior lights are not always working. On my warning display when i press it I get the sad battery face. how do I fix the problem. I did check the other threads but really didn't get an answer.

 

Sounds like some crossed or wrongly connected wiring.
