Last 14 months - 4 new batteries & new alternator fitted. Car still not starting and had to be returned to garage! Any ideas!

it sounds like your alternator is either intermittent/on its way out/or is not working at all ? find a garage that dose free quotes and get them to check your alternator

It is your alternator.

the car as a wire connected to the chassis and he is descharging the battery. you have to go to a car electrician and look wall the cables to see where he is not isolated.

Well the alternator is driven by a belt. You should be able to look at the alternator and tell if it has been replaced by how clean it is.

Look for loose connections on and from the battery---dirty /corroded earth etc.. PUll the starter and have a bench test done to find faults.

you may have another bad alternator or voltage regulator

As a simple preliminary test, try disconnecting the battery before you let the car stand for a while and see if it will start when reconnected. (If this will not affect radio codes and alarm systems). This will give you an idea if it is the battery or something in the car that is draining the battery.

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.

Try a day time running light modual,these things are notorious for messing up,and since they are supposed to work when the car is charging it seems like the logical solution.

the regulator is in the alternator. it sounds like it isn't charging the battery anymore. battery voltage should be around 14 volts with engine running. also check connections at alternator to battery. have seen corrosion here keep the battery from charging
