i had this problem for a long time. came to find out that it was the plug on the back of the alternator was loose. the rubber band around the plug had got worn down so i actually got so new bands at advance auto it solved that problem. also alt. belt may be loose too.
it might break your battery
Refer to your owners manual. It should have it listed under battery maintanence If light is still on you probably haven't fixed the problem so it might be your alternator or it could be your battery.
It is possible that your alternator might be going out. It also could be a problem with your battery. You should have it checked by a professional or you could be stranded .
if you meen NO LIGHT in the instrument pannel just check the battery, might be really dead
Might not be the battery ... something in the charging circuit (alternator, generator, voltage regulator, etc) could also be causing this "something's wrong" light to come on in the dashboard.
A flashing charger light usually indicates a problem with the battery.
A blower motor shutting off with a battery charge light lit might mean that there is a problem with the power supply going to the blower motor. A bad battery or alternator could also be the cause for this.
If the battery light is displayed when the engine is running, you may have a problem with your charging system. The battery display will stay on while the key is in RUN until the engine is started. If the message stays on after the engine is started, it could indicate a problem with the generator drive belt, or some other charging system problem. Driving with this message could drain your battery. If you have to drive a short distance, turn off all accessories such as heater, air, radio, etc. and get it checked right away.
The powertrain computer has to be scan to get the codes. The you fix the problem and with the scanner you clear the codes. If you disconnect the negative battery post it will turn off the check engine light and also reset the powertrain memory. But that might only solve the problem for a short period of time, and it might not work at all if the problem is present.
No problem if it's the same voltage, it will just last longer. But it might be significantly bigger, which could be a problem.

Take it to the car shop and have it tested under a load. Indicator might show blue = good battery but it still might be bad. Changed my battery out, reset the SRS light using the jumper wire method seen on the web and this fixed the problem. SRS light came on due to irregular voltage from bad battery. It was time to change out the battery anyways. Noticed map lights and headlight flickering during idle = bad battery or alternator. SRS light is still off on my car.
probably your battery is going bad - but could be the alternator as well.
