The other day I was getting on the highway and was behind a bluehair that got on doin 25mph, so I floored it to get around her. I noticed that my battery light came on when I did it, and turned off when I let off the gas. It only does it when I floor it, not when I goose it. I had autozone hook it up and it didn't throw any codes, they also tested the battery and alternator, both tested fine. Is this normal? By the way I have a 2000 V6 vert with lots of suspension mods, and only engine mod is a CAI. Has anyone else experienced this? What can I do to fix it?
