OK, so I have the battery light come on a year after I replaced the alternator which was from Autozone. I had a well know rebuilder check it out and he said the coill and regulator were pretty much toast. He also stated to check the batterty because the alternator was so toasted. I put in the rebuilt alternator and keep in mind the car always started strong. Battery is about 3 years old. I charged the battery and started the car and after 30 seconds I get the check charging system message. I checked the battery voltage and it is showing 12.2v when the car is not running. When the car is running I'm getting 16.4V to the battery, which I believe should be 14.5 range. So question is why is my voltage so high?? Could this be a bad battery or corosion of some sort causing it to provde more voltage then normal??? This was all done while the car was idleing. Or could my alernator still have an issue???
