Sounds like the brushes are worn down in the alternator.

Why does the battery light flicker and the car feels like it will die but it doesn't?

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


Why would the battery light flicker when accelerating to 3k rpm engine not fully warmed up on a 95 Mercury Sable 3.8?

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.

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!!!

Why do Headlights flicker and dash lights and battery light flicker and loose power steering whilst driving a vauxhall astra?

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.

Why does your battery warning light flash on when accelerating in a 1992 turbo dodge stealth?

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.


What would cause the battery to drain in your 96 Cadillac deville?

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.

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