You need a voltmeter. A fully charged battery is 12.6 volts. With the engine running the voltage on the battery supplied by the alternator should be 13 to 14 volts. A few auto parts stores will do the check for you if the battery has enough charge to get you there.
Check your RPO codes. If it has K60 then you have a 100 amp alternator.
Look at the top and left of the motor. It's easy to get to. The tension pulley is right below the alternator.
