One way to determine that an alternator is going bad would be to check the voltage at the battery terminals. Target healthy range with engine running and no major power draws is between 13.6 and 14.1 volts. Anything lower than this could be indicative of an alternator problem.
Since the alternator is the generator for a car, it is important to keep it in good shape and to give it proper maintenance. Listen to your engine for any unusual noises. Also, keep an eye on your battery light turning on, since this can indicate a problem with your alternator.
