Exclamation Battery light flashing?
The Title says it, what does this mean, and how can I fix it. The wiring on top of the alternator is in pretty bad shape. Is it only going to be a 5 minute fix because i need it to get to work tomorrow.

I didn't notice it when i was driving 60 down the high way, but when i got home I looked at the gauges and the light was flashing. I will hold around 2 thousand rpms tomorrow to see what happens

Mine did it too. Your alternator is on the way out if it is not a wiring issue.
Good luck

Mine would flicker at idle and slow cruising but if I reved it it would go out. It was my ground at one of my batts. not saying that will fix yours but it's something to look at

I should have put that better. It was the small ground that comes of the terminal that goes to the core support an the driver side
