well several things could occur. your lights look dimmer than normal, your alternator light will come on (if you have one, or its not blown), your battery light will light up(if you have one that is not shorted out or blown)and your car will run sluggishly thae finally die in mid transit from point a to point be. hope this helps.
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alt. You may also have a battery drain (something that is staying on and killing the battery)
D.C. - from a battery kept on recharge from the alternator. The alternator itself, as its name says, produces a.c., but this is fed into a rectifier included within the alternator case.
Check your alternator, that would be the main problem i think because the alternator charges your battery when in use, and with a bad alternator, means that your car is runnin soley off the battery and does not recharge the battery. Look into getting a new alternator. try testing the alternator at a local auto parts store, another test you could do is start the vehicle , and while it is running take off the battery cables, if motor turns off immediatly then your answer is that you have a bad alternator
The ABS light is likely coming on because the voltage being put out by your battery isn't enough to satisfy the requirements of the ABS system. It could be either the battery or the alternator. Put a load test on the battery and make sure that's operating within the requirements, and put a volt meter on the battery after starting the car to see the alternator recharging the battery. I've seen it both ways, alternator is bad and need a new one, or the battery is bad and need a new one.
Yes.Normally, the alternator charges the battery as you drive, and if if doesn't work, the battery never gets charged causing the battery to discharge. A discharged battery will have a short life, and is more likely to freeze in cold weather which ruins the battery completely. Note that an alternator should always be tested hot (within 5 minutes after driving for at least 45 minutes) . A bad alternator with a bad voltage regulator or rectifier diode may test good when cold.In some cases, an alternator may be "bad" because a rectifier diode (internal part like a check valve for electricity) no longer functions. With a bad diode, the alternator can, from time to time, actively discharge the battery when you shut the car off depending on the (effectively random) position at which it stops.
You either have a weak battery that needs replacement or you alternator is defective. Start the engine and check the voltage at the battery with a volt meter. It should read from 13.5-16 volts. Anything less and the alternator needs replacing. If it is reading within that range the battery is defective. Another possibility is a defective battery cable that is swollen or frayed.
A short in the car's electrical system, a bad alternator OR a bad battery.
If its totally dead (no radio, no starter) I would first look at your alternator/battery. This happened to my 2003 Trailblazer, and we had to replace the serpentine belt and the alternator. Battery light came on while driving and within ten minutes, the car was dead.
Bad starter.. direct ground..... stero equipment IG: amplifier being improperly wired . and it is possible to have the wrong alternator or a faulty one.

Good chances are, the alternator is not connected correctly or is defective.
Any belt in a car assists in moving all parts within the engine to work in providing power and cooling to vehicle. The alternator provides power to the battery and the fan cools the radiator so the engine will not overheat.
