OK, sounds like the alternator should be replaced.

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

Red spanner warning light


Brake Light. Make sure you are not driving with hand brake on. Check brake-fluid level. Top off brake fluid if low and make appointment to check brakes. Driving with brake light can be dangerous; deal with this soon. Call tow truck or drive carefully and slowly to shop.
ABS (antilock brake system) Light. Indicates either low brake-fluid level, stuck brake caliper or faulty ABS. Check brake fluid and make appointment to get brakes checked. Call tow truck or drive carefully and slowly to shop.
Oil Light. Either engine is very low on oil or there is no oil pressure. Pull over and turn off engine immediately. Check oil level and add oil if low. Turn engine back on to see if light has gone off. If oil light is still on, bad oil pump (no oil pressure) is likely. Call tow truck.
Check Engine Light. Car's computer senses engine problem. Difference in performance may not be noticeable, but make appointment to have car diagnosed. This usually cost around $65-$75 to do. OK to drive. If problem is serious, computer may switch to limp-home (low-power) mode and you won't have option of waiting to bring car into shop.
Air Bag Light. Get air bags checked. Problem could prevent them from activating in accident. OK to drive, but not safe in accident.
Battery Charge Light. Alternator is not charging. OK to drive, but turn off any unneeded electrical devices (radio, heater, defroster) and avoid starting engine more than necessary. Bring car into shop soon to avoid getting stranded. When alternator is not charging, battery loses charge and car stops working.
Emissions Lights (O2 sensor, EGR, check emissions). Depending on car model, these lights may indicate problem with emissions sensor or may light up at certain mileage, usually 60,000 miles (100,000 km). Get sensors checked. OK to drive. If problem exists, car might get poor gas mileage.

It's MOST LIKELY the Main Control Computer, available at Autozone, O'Reillys, etc. but I see you posted 01/08/2014 so I'd hope you have it fixed by now or you've probably been towed.

Battery not charging car is dead and will not start


Starting with the battery light, the warning light means the alternator is not charging the battery. It could be a faulty alternator, or a problem with the wiring between the battery and the alternator.
Normally you can drive a vehicle for several miles on the battery alone.
If you have charged the battery and it checks out ok, you would need to check the wiring from the battery to the alternator and to the fuse box for problems.

A red light on the dashboard can mean you should stop driving right away, or you may have a little time before you have to bring your car into the shop. Know what's what so you don't get stuck.

Battery warning light was on this morning , and for several miles altrnated between being on and off. After several miles it got dimmer and finally turned off. Car seemed to run all right though.


Replace the battery. The batter is on it's last leg and is about to die. The reason the light went off is because as you drive, the alternator provides charge to the battery. So the further you go, the more charged the battery becomes. That said, if the Battery warning light was on when you started the car, and you had not left any interior lights on over night, then the battery is losing charge rapidly or is not holding a charge.

My antilock brake system stopped working and my emergancy brake light is on even though the brake is down. the fluid is fine.


If the parking brake switch is not stuck and the fluid level is OK, try tapping on the fluid reservoir to see if the light flickers or goes off. (you need 2 people to do this) If it flickers or goes off then replace your fluid level sensor. (You may have to buy a complete reservoir or master cylinder depending on your car ) If this does not provide any results, then you may have an internal leak in your master cylinder or Antolock Hydraulic Control Module causing the Proportioning Sensor Switch to turn the light on. At this point. I would tow it to a shop and have the Antilock Control Module scanned to see why it has turned the light on and disabled your Antilock Brake System. I do not recommend driving the car at all until the RED brake warning lamp problem has been resolved. It is OK to operate the vehicle (cautiously) with the YELLOW Antilock brake lamp on.

Air Bag Light, Brake Light, & ABS Light came on in the dashboard.


Check and see if your alternator is charging
Low voltage will cause those lights to come on, as the computer is shutting down.

To check your alternator you will need a volt meter... WITH the engine running you should have about 14 volts coming out. IF NOT you need to replace the Alternator!
