So at Road Atlanta, my battery light kept flickering while in the paddock. If I gave it gas, the light would go away. Wasn't sure what to make of it, but Max Fischer had similar issues. Except for Max, he was racing in an almost hour long race. He lost his ABS and locked up all four tires into a wall. Luckily the gravel trap slowed him down.
Not wanting to risk a similar fate, I opted to buy a new (reman) alternator. From googling this issue, it seems fairly common that the stock alternator fails.
Replacing the alternator was fairly straightforward. Hardest part was messing w/ all the shrouding and removing the stock fan. I left the fan off since I wont be needing it.
