I have a 1993 nissan that burns an alternator once a year,i have just replaced it three weeks ago and now the battery lights come on and the belt squeaks when it first starts up

Have the alternator and battery tested this many warning lights come on most often due to low battery voltage due to a faulty alternator.

OK, try to replace the alternator with one that is 'lifetime' warranted rather than one with a '1 year' warranty or less.

Return the bad alternator to the auto parts retailer, and get a higher quality one.

I've had several bad experiences with one year warranteed alternators, some that were bad right out of the box.

I would say that the alternator is, again, at fault, but this time due to cheaper components causing your problem.

SOUNDS LIKE THE ALTERNATOR,HAVE IT CHECKED AT ADVANCE OR AUTOZONE FOR FREE.

Hi there, I am a girl (i.e. not car savvy), but I have a 1998 Altima as well, and the first time (4 months ago) I noticed the brake and battery lights on simultaneously, I took it to a Nissan service shop. Everything seemed fine until about a month ago when the symptoms returned. I ignored the problem for 3 days and the car just stopped running, period. Took it back to the shop, figured out it was a fauly alternator, got it sorted, no problem. Today (1 month after replacement), I see the same bloody problem, and I'm taking it back to the shop in the morning. I am wondering... is it the alternator, or something connected to the alternator that is malfunctioning? The 2 alternators put in were "rebuilt" since they didn't have genuine Nissan alternators available. I really hope the dealers aren't taking me for a merry ride.

you car computer needs to be checked. if the altenator was put in without unhooking the battery this could have fried your computer. for futher help and assistance please call 419 689 1114 for futher assistance i will be more then happy to help

replace the charging relay

Your problem is pointing to the alternator. Since you say the alternator is only a year old, the I would check the tension on the belt (deflection should be about 1/2 an inch), and the belt itself. Your problem most likely lies in either the belt, belt tensioner (if applicable), or alternator.

have the crankshaft sensor checked out on the car

Oxygen sensor might be faulty, as it causes the light to come on, but injectors hardly causes the light to come on, alternator( battery) light is an indication that the alternator needs to be replaced.

Tell us who made that belt so we can stay away from them.
