There is a very good posibility that the alternator is not charging. The easiest way for a do-it-yourselfer to check this is to get a voltmeter/multi-tester and check for voltage at the battery terminals before and after starting the engine.

Set the voltemeter to the 20 volt setting (or higher). At rest, the battery should register at least 12.5 volts. If the battery reads less than 12.5 volts, it might have a dead cell and may need replacing. Is it more than 4 years old? Replace it. It's due.

Battery reads at least 12.5 volts? Proceed to the next step.

Start the engine. The voltmeter reading should now jump up to anywhere between 13.8 volts to 15 volts. This indicates that the alternator is charging the battery and the battery light on the instrument panel should be off.

Getting a good reading but the light is still on?

Turn off the engine. Check for any loose wires/connectors to the alternator. If the alternator has a "field" wire (a small separate wire by itself), make sure it is connected properly to the single prong at the back of the alternator.

Removing a battery cable with the engine running was a viable charging system test back in the day; it is not recommended for computer-equipped cars such as yours inasmuch as the ignition system relies on the battery to "complete" the ignition circuit.

I hope this helped,
Have a great day!!!

Have to test battery to see if its getting voltage from alternator. put voltmeter on battery while car is running give it a little gas 2500rpm and check voltage should be 13 or over if not alternator is bad, if it is then shut car remove battery and take to auto store have them load test battery, or if u have a load tester , charge battery until full charge, connect tester and hit load switch for a couple of seconds , if it falls to red area then battery has a bad cell.

yes ideas.your altenator may be bad,or the belts broken to the altenator. look for yourself to see.if the belts are all on,then charge your battery and take your car to an autozone or advance auto parts store and they will check both battery and the altenator for free. if both check good,which it sounds like a bad altenator to me.they will charge your battery for free also,which then,you'll have enough power on the battery to drive back home,or a close repair facility. they will not[autozone or advance auto parts] replace,remove your altenator,but they can check it while it's still on the car.if it turns up bad,they can charge your battery fully,which with no headlights on,you can drive about 25miles with your battery FULLY charged.thank you for choosing fixya.com

Try checking the altenator. If the starter and battery were gimpy, the altenator may have a blown regulator too!. It sounds like there is a short in the system causing this problem. Most likely the altenator or component in the charging loop. WF

Why do my headlights and interior lights dim and then battery light comes on


Because your battery is low and your there is a problem in your charging system. Loosen the nut on the negative battery terminal, start the vehicle and then remove the NEGATIVE terminal cable. If you have cables that mount to the front of the battery then start the vehicle and remove the negative cable. If the vehicle dies your alternator or voltage regulator are bad. Most likely the alternator. remove and replace. If the vehicle continues to run turn the lights on and see if it continues. If that is good, drive to Auto Zone, and ask them to come out and help you test the battery. They have a portable machine that will test it for you or have you bring the battery inside and test it for you, they will even help you install the replacement battery if needed.

Car shutting off while driving


have you checked fluid levels. sometimes when they get way low, the check engine light will come on and the engine will go into self protect mode. when you replaced mass air flow senser did you clear the codes in the ecm(engine control module)? if the codes were not cleared the computer still thinks you have a problem and will try and compensate for it which would cause the rough running. one other reason might be that you have a loose ground and or positive battery cable. one quick check you can do is with the car running remove the positive battery cable if the car dies the regulater inside your altenator is bad and because the regulater is intergrated wioth the altenator you will have to replace the altenator completely.... rate this solution......thanks
