Installing an alternator on a dead or poor battery will cause them to fail prematurely. trickle charge your battery before installing a new alternator. check all connections for corrosion especially grounds.
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.
The alternator belt on a 1993 Nissan 300ZX will typically squeal if it has excessive wear or it has become lose. This provides a good opportunity to replace the belt before it complete fails.
Clean it out!! water will not hurt an alternator but Antifreeze will breakdown the varnish on the Stator windings! Oils is bad but Antifreeze is worse.
I had a similar problem turns out the Alternator was bad.
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
Remove the alternator belt from your 2000 Chevrolet Monte Carlo alternator. Remove the wiring harness from the alternator. Remove the alternator retaining bolts. Reverse the process to install the new alternator.
alternator does not rotate
When MBR fails then the operating system will not load.
An alternator keeps the battery charged in a vehicle. In a 2006 Chevrolet Impala when the alternator fails the battery will keep dying and no power will be available when attempting to start the car.
The alternator only needs to be replaced when it fails. Its not a part that needs to be changed during routine maintenance. If it ain't broke, don't fix it!
Only when it fails. 250,000 miles would be average.
Alternator fails to supply power.

Try it
you would die
You will have to go to a doctor.
If your digestive system fails you will suffer and possibly die from malnutrition.
When interpositional reconstruction fails, total joint replacement may be necessary
