Quote:There were no powerful mosfet transistors in 1970, the technology used was a coil with a set of contacts (cb550) and a spring that was set to maintain 14 volts dc. and six diodes.
Which coil are you referring to (stator, field, rotor, or ignition) and what is the spring you are referring to?

This small coil was inside the regulator and maintained the 14 volts against the( adjustable ) spring tension.
It was the most common regulator system used on all vehicles at the time, it's mechanical/electrical, the more tension on the spring the higher the regulated voltage, the spring is the equivalent to the float height in the cistern.
The spring would pull against the magnetic field, if the magnetic force was getting stronger ( higher voltage ) it would overcome the strength of the spring, open the contact and break the supply to the field coil, voltage would lower, contact would close again etc.
so it would be vibrating in it's own rhythm and maintain 14 volts
