It's either been overloaded trying to charge a dead battery and fried itself, or there may be a burnt out fuse. Check connections and have the battery tested.
The light is on because the alternator is not putting out the required voltage. Either the belt is broken, loose, or the alternator is defective.
13.5 to 16 volts.
No, because after the car is started, even in traffic, your alternator is putting out the voltage, and that voltage is controlled by the voltage regulator. What Will be affected is your gas mileage/.
Voltage flows from the alternator not to it. If it is outputting no voltage it is defective.
Sounds like a bad alternator. Slow windows indicate low voltage (same for radio cutting in and out), the alternator light indicates battery voltage is higher than alternator voltage (most likely meaning alternator isn't putting out anything).
13-15 volts, depends on what the computer wants.
have an alternator, battery, and electrical check to find out what the problem is. battery may not be taking a charge, or the alternator is not putting out enough voltage.
It normally means the alternator is not putting out enough voltage to keep the battery charged and is defective. Can be a loose alternator belt also.
The car may need a new alternator.
Check your alternator, it will cause the engine to miss if it is not putting out enough voltage under a load.
The battery is bad or the alternator is not putting out the correct voltage and is bad.
Yes, the job of the alternator is to recharge the battery and run all the electronics when the car is in use. If the alternator is defective and not putting out the required voltage to keep the battery charged it will soon run down.
