It is possible that 'wires' can cause an alternator to fail - such as dead-shorts in high power circuits. More often though the bearings go bad, or the internal components wear out. One other source of problems for alternators are bad batteries causing high-stress/strain - can lead to premature failure. See "Related Questions" below for more

There is several things that can cause your battery light to come on. Go to your nearest Advance Auto Parts and have them hook up the battery and alternator tester because your alternator could be bad, or if you have a lot of electrical products such as a powerfull stereo system, gps, DVD player etc., you could be drawing to many amps for you battery and alternator to keep a charge
The alternator normally has absolutely nothing to do with the fuel pump. However, since they are not too far apart, in the process of replacing the alternator, something could have hit the fuel pump and damaged it. So, while there is an extremely high probability the two are not connected, there is a possibility they are connected.
Why wont your battery light go off when you changed your alternator and battery in your 99 mercury cougar?
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 alternator and battery. You may also have a battery drain (something that is staying on and killing the battery)

Can an alternator short out for years And have problems for periods at a time for a matter of 3 years or so?
An alternator cannot "short" out for years or even minutes. The definition of a short is a wire or circuit touching ground to cause a fuse to blow. The circuit is too "short" for the current to flow through the proper load and back to the battery. The voltage regulator in a alternator can act up from time to time and cause improper charging from the alternator. Or a component of the alternator can go…

Bad diodes in the alternator can cause the battery to go dead when the car is off. The diode bridge (six diodes) is directly connected to the battery, and is used to convert three phase delta AC from the alternator's stator to DC for the battery. Normally, if the engine is not running, the diodes are reverse biased and do not conduct current. If one of the high side diodes is shorted then the diode…
What would cause a battery light to come on intermently other the alternator its like if you speed up it will go off but then turn car off its back on could it be the maxifuse its a 99 ford contour?
As with many electronic devices they can merely fail over time. I have heard it said that jumping the battery can cause the ECM to fail, I don't know that to be true. Too high a battery voltage could cause failure of the ECM. That might be caused by the alternator putting out too much voltage when charging the battery.
