Sounds like the brushes are worn down in the alternator.

Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alt belt.

Clean both battery cables and check the connections on the alternator. If it continues, go to auto zone and have the alternator checked.

Clean the battery cables and make sure the wires to the alternator are tight and without corrosion.

If the battery light flickers, it's losing voltage. It would be worse when the lights and other accessories are running. It just may not be enough to kill it yet. I would suspect parts in this order. Alternator(if there is a voltage guage, should be around 13-14 volts) discharged battery

The warning light doesn't tell you how healthy the battery is, it tells you if there are any problems with the charging system. A flickering light means charging is intermittant for some reason, so it would be worth checking the alternator or voltage regulator, which might be on the way out. It's worth also checking that the warning light circuit and bulb are ok - if it lights up brightly and continuously when you switch the ignition on, then goes off when you start the engine, it's ok. Hope that helps.

Why would battery light come on then go off

i would say no because the battery has a lot of energy to pass to the light bulb and not a pataoe

Most likely, the alternator is going out. It puts out more at higher RPM's, so it would charge more going down the road than it would at idle. Good Luck!!!

Your battery is not charging due to a problem with the battery cables or a bad alternator.

Not enough power to starter, jump it and then ensure alternator is good. Also check battery condition.

on my old 1.2 clio the battery light came on as there was fault with the alternator and it needed replacing. As far as i know the battery light comes on when the battery is not charging or there is a fault with the battery.

you have a loose connection somewhere on your vehicle check battery cables and alternator connections i have the same problem i found out what it is by the brake and gas pedals.. where the code reader goes under neith that is a black box i thinks is a power coverter i dont know yet but i unpluged it and the dome light when out but no more flicker i will up date when i found out more about this box I would think that you have a problem with the serpentine belt (also called drive belt) if it is loose it will cause the alternator not to rotate making your lights flicker and since the power steering is connected to the same belt it will also cause a low fluid pressure making your steering wheel hard to steer.

This light is warning you that there may be a problem with your battery. Have it checked.

Can be the battery has a dead cell which will require the battery be replaced. Can also be anything on the vehicle that is on pulling from the battery. Any light that is on or any relay that is stuck will drain the battery. Check under hood light, trunk light, glovebox light, interior lights, etc.

This could really mean several things. The battery is not working properly. The alternator is not working right. A loose connection in the battery or alternator connections that only seems to show up accelerating. Possibly where it is. The drive belt is slipping and if this slips the alternator will not be charging the battery fast enough to replace the charge while accelerating. I would start with checking all the cables for loose connections and corrosion. Then I would check the belt and make sure that it is tight and in good shape. Then I check or have the charging system checked. If you know how to use a digital voltmeter you can check the charging system your self. The amp should not go below 13. If it does then the alternator is bad. On the other hand above 15.5 amps and the alternator is frying the battery. Hope this helps. Good luck.

The ABS light is most likely on because of low voltage, same reason for the battery light to be on. Get your alternator tested.

A person walking in a straight line at a constant speed would not be accelerating. A person standing still in one spot would not be accelerating.

User Avatar

yes if one of the wires was getting an earth from the alternator cover or rubbing off the engine the battery light is really an alternator light warning you that the alternator is not charging the battery

Usually when the battery light comes on its the Alternator, or a bad wire from Alternator to battery, but id check Alternator first.
