after accelerating on freeway my battery light came on my headlights (low beam) blew out & my radio stopped working all at once. this is the 3rd time in less than a month & all after the alternator was replaced. (RADIO WILL RESUME, NO BLOWN FUSES BUT LIGHTS R TOTALLY BLOWN) Can someone tell me wats going on?? also the other day im on freeway & all the sudden it felt like someone stomped the brake real quick like & the battery light came on. It scared the bejesus outta me. Is it my alternator causing all of this since none of this ever happened b4 replacing it? Oh one more thing i have a screetching squealing sound thats been coming frm idk the belts?? have replaced them twice now only to have a worse louder sound. it does it whenever where ever, cold running hot running just on & off all the time except when on freeway going fast. in City stop & go will do it sometimes & not others. Does it a lot of times when first started. HELP PLEASE
