I have replaced my alternator 2 times in the last 10 days. The first time I replaced it, I did not replace the battery at the same time. I bought a new battery and then it went out same day. I got another Alternator and it worked well for about 5 days then today, the emergency brake and battery lights come on. I also notice a rough idle when those lights are on. All of this happens once the car (and alternator) are warmed up (about 5-8 minutes after start up). For a while, they just flicker but then they just stay on. During this, the voltage is usually normal when revved but really low when idling or coasting to a light. I do not remember the exact numbers. I am hoping I have just been sold another bad alternator. It is under warranty so it will be free. Can someone help me?
