There is a reason these were originally called 'idiot lights' because they don't tell you much.
Normally however, that light is telling you that the battery is no longer being charged or cannot accept a charge. If you have a chain auto parts store in your area, call them and ask if they do free alternator and battery checks. They mostly do since they sell both of those items.
I would also recommend while you are there, look at the digital multimeters they stock. If they are under $20 US, you might buy one for future problems; they are very useful for quick auto and home electrical checks and simple to use even while the translation into Chinglish is sometimes amusing.
If you use eBay, you can find an even cheaper multimeter there.
Checking only across the battery terminals will show if the alternator is functional since they typically put out well over 12.6 volts even at an idle. However, a bad cell in the battery can also drag the voltage down but will generate considerable heat in the battery.

Why won't my 2000 Ford Expedition turn on. Is the battery dead when lights won't come on or it won't light up inside. Dash won't light up. Nothing comes on.

IF you have no power then 99.99999% the battery will be dead. So it will either need to be charged if it will still hold a charge or it will need to be replaced. There may also be other issues(see 2) but that is where to begin.

You might also try and start the vehicle using jumper leads connected to another vehicle. After the leads are connected properly , start the engine in the other vehicle and then try to start your engine. You do not always need to start the other car but you will if the battery fitted to the other vehicle has insufficient cranking amps to turn over the starter motor in your car. If your vehicle starts and you have normal power to lights and accessories once your engine is running (and you are disconnected from the other vehicle) then you know your battery is possibly the only issue.

How to Jump Start Car

2. However, your alternator must also be providing power to the vehicle when it is running and the alternator also charges the battery whilst your engine is running.. If the alternator is faulty and not generating the power supply, your battery will be the only power source and it will run down very rapidly. In your case(with a 2000 model vehicle) I would definitely have the alternator checked to ensure it is generating the required power because eventually these components do fail and need to be replaced.

My 2003 Buick rendezvous battery light came on, my battery is only 10 months old so it kinda new. What else could be the problem? Because it starts up fine.

The "battery" light really isn't just about the battery. In fact, it often has nothing to do directly with the battery. The Battery light indicates that the charging circuit (alternator/regulator) is not supplying sufficient power to run the vehicle, and thus the additional power needed is being drawn from the battery. In normal conditions, the battery is only needed to start the vehicle. Then the alternator provides power to the car/truck and at the same time charges the battery back to full power. If the battery light is on, have the charging system checked. Often the alternator is going bad.

Battery light on my message center

Hello...A red battery light or image usually means there is a problem with your charging system..either your alterator is either not operating or emitting low voltage usually because of diode failure...alternators generate Alternator Current(AC) which is the same of household current...but the vehicle can not use this...It doesn't even register...The alternator has diodes which convert AC current to DC(Direct Current) which the vehicle can use....If the alternator is not doing it's job...The vehicle will pull current from the battery while the vehicle is operating..which is not good.The alternator should be able to run the vehicle...all the accessories...and charge the battery all at the same time...Drive it into an auto parts store and have them test your charging system before you get stranded...and most of the time...the car will die at night because of the headlights.....Let me know what happens...I hope this was helpful.....PEACE.....

My Honda passport will not start. Its not the battery because the lights are on in the dash and battery is good i do hear a clicking below but not starter fusses are good however is there a fuse in the...

The clicking sound indicates that the battery is too low to start the vehicle. Accessories such as dash lights draw very little current, so they will work even when the battery is nearly depleted. Try removing the battery cables (negative first) and cleaning the cable ends and battery posts with a wire brush or sandpaper. Then check the water levels if yours is a serviceable battery, add distilled water if needed, replace and tighten the cables, then try to jump start from another vehicle. If it starts, let it run for a while and see if it will start again by itself. If so, that may be all you need. If it continues to lose its charge, you will need a new battery. If the vehicle will not start even with the jump, you may need a new starter.

The car won't turn on at all. The lights won't turn on, the hood won't go up. Its completly shut down and was just charged last month.


There are two main possibilities here.

1) The battery is flat because it is no longer holding a charge. The ability of a battery to retain a charge will diminish over time. In this case a replacement battery is needed.

2) There is a problem with the alternator which is not supplying charge to the battery when the vehicle is running causing the battery to be drained over a period of time.

You can test for both of these using a multimeter and this is very easy to do.

1) With the meter set to the DC scale and attached to the terminals of the battery (Red lead to Positive, Black to Negative) and with all accesories turned off - you should have a reading above 9.6 volts. If the reading is less than this the battery is faulty and needs to be replaced.

2) If the reading is above 9.6 volts, you need to get the car running in order to test your alternator. You will need someone to rev the engine whilst you connect the meter to the battery. With the engine at a fast idle, and all accessories off, the voltage on the meter should read around 14 volts (13.5 to 14.4) showing that the alternator is producing a reliable charge.

Anything less than 12 volts with the engine running means the alternator is at fault and it is the alternator that needs to be replaced not the battery.

You can also test with accessories on (heater, lights etc,,) The reading should still remain around 14 volts with these extra drains on and the engine at fast idle. Anything less is an indicator of a faulty alternator being the cause of your problem.

Hope this helps. Thanks for using FixYa.

Check guages light comes on after short drive while engine is running, and the car died while driving on I-95 the lights started flickering getting dimmer. the radio would turn off when anything else...

It sounds like the Alternator is actually bad.
One great way to determine this:
Recharge the new battery with a trickle charge overnight. Make sure use remove the wires going to the Battery before recharging.
Replace the Battery Wires.
Get the Vehicle Started.
When it has Started: Leave it Running and Disconnect and Remove the Negative side of the Battery. If the Vehicle dies, it is the Alternator that is bad, and needs to be replaced..
The Battery starts that vehicle, and provides nominal power to certain accessories. The Alternator actual Runs the Engine and Recharges the Battery with a low trickled charge.

Battery has been replaced light does not go off

You may need to have the error code reset by the dealer. Once the cars computer senses an issue it will lock it in untill repaired and reset. The only other possible problem is you alternator. If you alternator is going bad it is not sending enough power to recharge your battery properly. A new alternator can be replaced for under $200.00. Lets hope it is just an error code that needs resetting. Take care and please leave me positive feedback. It means a lot to me. If you have more questions do not hesitate to send them to me. I will do anything I can to get you taken care of. Have a good day.
