Actually the best and safest way is with the volt meter. it shouldn't matter if you check it at the battery or the alternator unless your battery cable is corroded. If you check the voltage at the battery before starting the car and then after it should go up while the car is running, at least 13.5. If I just went through and couple Transpo voltage regulators with a 100 amp alternator, seems that is to many amps for them. Installed a 110 amp si GM alternator and I get 14v at indle with everything on including the electric fan.
