ok so i replaced my alternator yesterday .. and now it broke again. is this a faulty alternator or is something wrong with my car anyone has any idea ? thx guys

 

yea same thing happened to me before. just get another one from autozone and you'll be straight

 

'broke again' how? Undercharging? Overcharging?

OEM alt?
Aftermarket? (New? / Reman?)
Junkyard?

 

duralast from auto zone . its not charging .

 

it charged for like couple hours and the the battery and ebrake light went on

 

And of course you checked connections, fuses, made sure the belt had the right tension? Tested the alt and battery?

 

yeap my mechanic tested everything .. i was there with him,i though it might be battery but it came out good , so was the fuse and the connections

 

i've found the ones from autozone are not very good and either don't work when you install it or stop working a short while later. Take it back and buy one from Nissan. While it may be a few bucks more, it'll save you more headaches down the road.

 

And you know this by getting your charging system tested ?

get the alty tested,
does the car turn on and run with the lights on ?
Are the lights intermittent and randomly come one and come off ?
