sounds like you need to replace the battery. even new batterys sometimes are no good
also an alternator tested when disconnected means it is tested with no load. this really means that the test was a waste of time
The charging warning light should automatically reset if the battery is disconnected. Check the battery cables and ensure they are properly connected. Also check the alternator connections. If the light is still on there may be a problem with the new alternator.
I think your alternator doesn't work properly.
Many possibilities. Check in theis order: Bad battery connections? Bad battery? Loose alternator belt? Bad alternator connections? Bad alternator? (Test at auto parts store.)
Make sure that all wires are connected properly on the correct connections. Make sure that the battery connections are clean and tight. This may help with the problem.
Indicates a problem with the electrical charging system. Can be a bad battery, alternator, loose alternator drive belt, corroded battery connections, or ground connections. Normally this would indicate a problem with the alternator but not always. Most auto parts stores will check the system free of charge, if you buy the repair parts from them, which would only be appropriate.
Its a good possibility Your diodes are burnt out, its time to replace your alternator, i had a similar problem on a 95 lumina with a 3.1l motor
This would normally mean a problem with the alternator. But it can also be loose for corroded connections.
Most are controlled via the output from the alternator - You will need to check all connections on the alternator first. If there is no suspect.damages/loose connections then its likely the console/display will need replacement due to wear.
There is no problem...the problem was the alternator. You have fixed the problem.
If you can jump it and get it running again, drive it for a few miles and then it dies again, it is the alternator. Buy a new alternator and it will fix the problem assuming you do not have bad connections "wires" in your charging system "your alternator and your battery".
I've had the same problem with mine. It was a low voltage problem. check all your connections, clean the terminals, make sure your battery and alternator are good.
It's a job you need an experienced mechanic for. First you need to disconnect the battery. There's a protective cover inside the front passenger wheel that has to come off. The alternator has a serpentine belt that connects to it so that has to be loosened (a tricky job in itself). All the connections to the alternator should be disconnected and ideally marked for replacement. Reverse the process to install the new one. It's really a tight fit to get to the belt and alternator. I've replaced a belt on one and it took a lot of time and a great deal of patience . I did it on the ground with no lift so that added to the problem.
