I have replaced the alternator 3 times in the last year.Now I am told that there is a inherent problem with the heater timer in this model and that the heater stays on which causes the alternator to burn out. The auto timer was disconnected but now I have burnt the alternator for the 4th time! Any solution will be appreciated.
Have your battery checked with a car battery testing machine. It may be on it's way out.
If your battery is flat it can ruin your alternator. If this has been a problem, don't just bump start or jump start the car then drive a few miles, you need to charge the battery FULLY with a charger plugged into the mains.

There is only three things that would have happened.
1: First check your fuse panel, check all the fuses . if none are dead try the second step
2: take out the alternator, go have it tested, the diodes may be fried. If the alternator is bad there ya go.
3: if the alternator is good (lucky) And it still does not run , then your ECM and PCM are fried. In which case you will have to get new ones which will run a pretty penny ( $500-$1000.00)
you might get lucky and find a set in your local junkyard
good luck and let me know about your alternator
My friend is a Honda Vehicle Technican who owns a 1994 Nissan Sentra which had kept dying on him. He had called the AAA driver who stated that the alternator was good as noted on the print out report when the AAA driver ran the check on the system. It turned the alternator was bad, which somehow also affected the starter. While the AAA driver had jump started the car, the ignition switch relay got broken; and the small positive cable connection got a short; so it all, he replaced the alternator, the starter, the battery and got a new battery cable connectors, ignition switch relay and fuse for the inside of the interior lights -- and he has no problems since after spending 4 days on this problem. It would had been easier had he had a lift and the right equipment but nevertheless he got it done but missed his work -- but at least its fixed.
Hey! I have a 97 Maxima SE and it runs great too! I have been through 4 alternators in 12 years....3 in the first 5 and finally one for the last 7. Make sure you have a new- Nissan part specific alternator. And, make sure your battery is not weak nor small for your car size. Hope this helps!
