ok so 4 days ago i suddenly smelt something wrong......like fire/short wrong. then my battery light came on. now before this happend i noticed that at night my lights had a surge up and down to them. ok, figured the alternator, due to the fact my car died about 5 minutes after the radio shut off. well replaced the battery and the alternator, thinking problem solved. well starts up but the battery light is still on. ?? what gives? did i get a bad alternator? i havent had it tested yet due to work but has anybody had this problem? let me know. thanks .
