This is why the battery need to also consider its charge from the leading distribution position - Hence the method is in equilibrium and we do not hazard sending sixteen.0 volts directly to a battery due to the fact That is what the alternator is outputting to keep the primary distribution level at fourteen.0 volts.

As We all know, after the motor is started off, as well as the alternator is producing electric power the diode trio feeds the alternator output again towards the regulator to serve as the sphere latest supply.

Output. This link carries the charging recent within the alternator to the battery, and corresponds towards the screw terminal over the back again in the GM unit.
