Thread: Alternator Killer - Help

1 year old ve swap in my NX, well after a second track day second alternator (nissan OEM) is finished! Voltage on my battery is 12.2V with the car on (was 13.8V before the track day)
I need suggestions of what is killing the alternators as the track days are getting very expensive for me.

Thanks.

you ever happen to find out whats causing this, my 92 started eating alternators
