Some what the higher of the two. Look at the voltage with engine off (battery) and compare to when it's running (alternator). The output from the alternator exceeds battery voltage, about 14.8 or more iirc. This simple test will not deterine if the alternator is capable of full output load but it will quickly display if your alternator is kaput.
