Well guys, I went and looked at my girls car. Everything seems fine. I checked the tension of the belt, felt great to me. The belt is a little beat up, and it could really use a good replacing.
Other then that, I turned on the AC full blast, head lights, 4 ways, and cranked up the sterio and there was no light for me.
The only thing she was majorly worried about I guess was when the light came on her power stearing went out for a few seconds until she turned the sterio and defrost off.
Hmm
Autozone said the battery and the alternator are in great shape.
I told her to just run it and keep an eye for anything funky.
I thank you guys so much. Even if none of what was informed to me wasn't used today, it will be down the road. You guys taught me a good bit about the alternator, etc.
Thanks guys.
