the only reliable way of determing if your alternator has gone bad is to have it tested by an automotive electricial specialist. That is because most modern alternators have the voltage regulator built in, so just testing to see if it is generating will not tell the whole story. Warning signs of alternator/voltage regulator failure are dead battery, but battery can be charged, lights dimming and getting brighter while driving, and hard starting.
