The voltage is controlled by regulating the amount of current flowing through the field windings, which in turn regulates the electromagnetic field strength. A generator dont necessaruily know what its voltage is supposed to be, the faster it turns and/or the more field current the more it generates. When hooked to a load like a battery which is similar to a big capacitor bank capable of storing electrons its voltage is somewhat stabilized as opposed to running it wide open and unloaded. The old light switch controllers offered just 2 charge rates, a dead grounded field for high charge and a resistive ground for low charge. A Voltage Regulator gives more precise control cuz its relay contacts can pulse and time the field current versus ONLY a 2 position setting.

The battery fully charged and setting is 3 cells of 2.1 volts each for 6.3 volts so if you apply just 6.3 volts she wont charge as theres no net current flow into the battery. Usually the cutout relay dont/cant even latch in till the gens voltage exceeds that of the battery at say 6.5 volts or more, or else the relay is bad or misadjusted or has burned or carboned contacts. The field current control relay points may also be burned or carboned resistive so as not to allow sufficient field current for a good charge. Try to non abrasively clean/buff/polish all the relay contacts (field control and cutout relay) which may help an ailing voltage regulator. Make sure the belt is good n tight also and that the VR has a good frame ground as well as the generator itself !!!!!!!!!
