When an alternator goes bad on any vehicle, it drains the battery of power. If lights are on, it will drain even faster and you will notice the lights go dim until eventually the car dies. You can not drive long without a properly functioning alternator. It is though, a standard replaceable part much like water pumps, tuneup items etc.

Without the alternator in operation, everything electrical will only run from the battery, which will discharge rather quickly at which time the car will cease to run. Without any charge in the battery, the car won't be able to be started.

A failed alternator is no longer is able to supply electricity to your car or to charge your battery. Only the battery will then supply power for your automobile until it runs out of energy. In a gasoline engine, the depleted battery will no longer be able to supply current to the spark plugs and the car will stop running. A diesel engine will continue to run since it doesn't require spark plugs. Additional info directed primarally to Automobiles There are three basic failures:

1st Failure to charge, Normally a little light comes on on the dash board, the battery goes dead and the car stops or wont start.

2nd Very Rare. The alternator runs away, ruinss the battery and potentially starts a fire

3rd The alternator siezes. When that happens the either belt breaks and the engine overheats or on many GM vehicals the engine stalls and won't turn over, acting like the engine is ruined.

An additional note on the matter of diesel engines... saying they'll still run only holds true for older, mechanically operated engines... present day diesel engines are controlled by an ECM the same as gas engines are, and will shut off once power to the ECM is lost.

Your vehicles primary battery will drain eventually causing it to not start. If you drive for a long time with a dead alternator the vehicle can (rarely) shut off.

What would cause the alternator warning light to come on in a 1979 Chevy Malibu?

Its telling you that for some reason the battery is not charging. Possible cause are: poor or dirty cable connections at the battery posts, bad cables, bad battery. It is also possible that the brushes in your alternator are bad but, the fact that you are getting a light usually indicates the problem is with the battery or cables. For some reason on a GM alternator when the internal regulator in the alternator fails you don't get a light. The only indication you get is that when you turn on the key the battery light doesn't come on. So it is probably not the alternator. Check for corrosion around the battery cables where they connect to the battery. That is most likely the problem. If you have the type that screw into the side of the battery, they may have just worked loose. Good luck
