2004 Nissan Altima 3.5L BATTERY LIGHT went on during 15 minute drive. Next day car "died" while idling after a 20 minute drive. BRAKE WARNING LIGHT & BATTERY LIGHT on prior to full electrical failure.


Start with checking the alternator voltage with a multimeter. With the car off check the voltage in the battery which should be holding 12v charged less if flat of course then start the car and test the battery again. If the alternator is good you should be getting a reading of 14 to 14.5 v if it's the alternator it'll A) not put any charge into the battery or B) be a very low voltage being anything under 13.5 v

Low battery light comes on, then goes off, followed by the seatbelt light to start flashing. Took for a drive today, same thing happens, then all other warning lights come on and car just goes dead in...


It sounds like your battery is not charging. You may have a good battery and a good alternator but what you need to look for is the alternator fuse . It is usually a square block style fuse , 50 to 80 amps, normally in a fuse box under the dash. If it blows the car will drive till it runs out of battery juice and go bonkers just like you describe right before it dies. The charge light on the dash usually will not warn you of the problem. I think the manufacturers just want to charge you big dollars just to replace a fuse most people are not familiar with.

2003 Cavalier. Battery warning light came on


Check for bad connection to the battery. Use a volt meter to check voltage from alternator to the battery, should be 14.5 volts to 15 volts. If you have anything less than that then look for a bad alternator wire from alternator to battery. Also check for a good ground connection to the battery. Do all the testing with everything off inside the car so you will not have a power drain from the system. hope this will help you.

My fuel light just came on and battery charge light just came on. I put fuel in it, but it still remain lumininated. what do u think is the problem. is the battery dieing?


it is the alternator. 100% Once the alternator goes out it is not uncommon for the lights on the dash to act strange. Go to your local parts store and have them do an alternator output test. Don't go driving too far because when that battery goes dead the car will die also because the alternator is not keeping a steady charge.

I just replaced the battery on my 1999 Suzuki Esteem wagon. How can I test if the alternator is working properly?


Your car has a warning light for the alternator,for one.and most of your garages will test your alternator for free if you are their customer.If your alternator is working properly the alternator light on the dash will light when you start the car and then go out all the while the motor is running.

MEANING OF DASH BOARD WARNING LIGHTS


Hello If it looks like a battery then most probably one of two things. 1- You have a bad battery. 2- You have a weak alternator that is not functioning properly and can not keep up with the car needs. You should check the alternator charging value and then check the battery. You could do that at any shop that has the Battery/Alternator testing tool. Hope that helps

While driving, all warning lights on dash suddenly were lit. When I stopped the car, it wouldn't start again and sounded as though the battery was dead.


Probably the alternator died, then used up all the power in your battery to keep the car running.
Have your alternator tested and maybe replaced. The battery needs tested also.

Hope this helps
