Alternators can fail in many ways, two common ways is they don't produce proper voltage and amperage out put or they can make noise when bearings or clutch pulleys fail. A failing alternator can also be a symptom of another issue. Properly diagnosing charging systems is very important on modern vehicles.


Just because a battery has 12.6 volts doesn't mean its still good. Batteries have to pass many tests and provide not only voltage but enough amps and reserve capacity to keep today's vehicles running properly. If your car cranks slow, the clock or radio resets or your vehicle has to be jump started after a weekend of sitting perhaps its time to have your starting/charging system looked at.
