I just replaced my alternator (autozone alternator)
The car starts right up however when i rev high 3-4k rpm, the ABS, VSC, and battery light come on. I checked the serpentine belt, fits correctly.
When I let off the battery light turns off however abs and vsc stay on. The lights only come on after revving.

 

I would suspect the alternator. When the battery light comes on that normally means the battery is not being charged by the alternator. If that is correct, use a Denso OEM or rebuilt OEM alternator, I would also scan for any codes causing the ABS and VSC lights to come on.

 

Lots of problem stories with aftermarket alternators in this car. Why did you replace the alternator in the first place? Just curious.

 

Car would die after jumping every single time, would pull the key out and all the lights out.

 

Update* Just tested the alternator, Voltage regulator is definitely the problem, when revving the car, Volts jump to 18. Should I replace the alternator altogether or try to replace the voltage regulator

 

Replace the alternator. The voltage regulator is inside it.

Get a replacement from AZ. It should be under warranty. Expect them to test it and give you flack.
