My lights would start to fluctuate, so I went in and had the store test it, and it would show a failure on the voltage regulator. Alternators can produce 100 volts or more when they're not connected to anything and there's no load placed on them, and the voltage regulator in the alternator can immediately switch to max power under these circumstances.
In my experience, it's either the brushes magnets or the voltage regulator that break down the soonest. Otherwise, the charging system can't meet the demand and charge your battery. If the system is generating around 14-volts with the engine running, then you can reasonably conclude that the alternator is working properly. Consult your vehicle repair manual, if necessary, to locate the alternator fuse or fusible link. Actually, it could mean a number of different things, including engine troubles or a dead battery.

Bad outer and inner alternator bearings large and small silver cylinders in the cutaway image above can produce a whining noise. And if not at least check for a remanufactured date. Another alternative is to have your alternator rebuilt. If it stays on, there is a problem with your charging system. It isn't power steering so I am pretty sure it's the alternator. The spark plugs and other things need electricity that would usually come from the alternator is now coming from your battery.
