so,i bought a 99 camaro z28 back at the end of may,has 101k miles on it.in june,i had to replace the alternator cuz it went out,car ran perfect until 2 days ago wen the alternator stopped chargin the battery.so i took out the alternator,which is less than 3 months old,brought it to autozone and they tested it and said it was bad.i got another replacement,installed it,and my battery still isnt chargin.i tried my brother news battery that he has in his camaro (just in case it could have actually been a faulty battery) but it still did the same thing.so just wondering if it can be a bad wire,bad fuse or engine computer or something that is bad which isnt lettin the alternator charge the battery.wat do yall think??

 

Have you checked the single red wire that goes from the alternator to the battery? Possibly corroded, damged or loose?????

 

yeah, check the terminals and connections at battery, alternator and fuse box for corosion. I added a chasis ground at the alternator, and ran a heavier power wire from the alternator to the battery because I was having the same problem randomly, my alternator tested good 3 times though. But I have heard of a number of people that have gotten defective alternator(s) from autopart stores, so thats also a possibility.

 

well I finally got sum free time to check the wires for corrosion and what not and sure enough the red that connects to the alternator ended up popping.I think it happened when I installed the new alternator and after I fixed the wire my problem was fixed.so thx for the replies and help
