It's pretty simple, if you have access to a digital voltmeter, which can be had for
as little a $5-$10 at a discount store. The voltage of 13.8 volts on any standard
12 volt automotive vehicle is about the average, when an alternator is properly
functioning, while the vehicle is running. If it measures over 14 volts, the voltage
regulator is shot. They are mostly attached to the alternator these days, but can
be remotely mounted to the firewall in older vehicles. To test the alternator, just attatch the meter leads to the battery terminals. Red for positive, and black for ground.
Make sure the meter is set to the Volts DC Scale,so you get a proper reading. Check
the voltage with the vehicle off, which should read around 12 volts and while the engine is running, around 13.8 volts.
