Increase Alternator Voltage Output #1

In this manner, the system is a closed feedback loop that self-regulates. In practice, as engine / alternator rpm drop, alternator voltage output drops which the regulator senses and as a result increases the field current to the rotor which brings the output voltage back up at this lower rpm. It works in reverse as well - higher rpm means greater voltage output. If it gets too high the regulator senses it and cuts back the field voltage, bringing the output back down.

    To charge the battery, the alternator voltage output has to exceed a charging voltage. This minimum charging voltage is 13.8 volts dc across the battery terminals, or at the output of the alternator. A single lead-acid cell starts to charge at anything over 2.25 volts. Since a 12 volt battery has six cells, any 12 volt lead-acid battery needs at least 13.8 volts to to charge. This voltage will be enough to fully charge or maintain the battery on a trickle charge, but charging time will be very long at 13.8 volts.
