Anyone Running A Mechanical Voltage Regulator 67 Dart 273 2bbl
Mattax posted this excellent electro-mechanical drawing of early voltage regulator.
Electrically it looks like this:
It is a basic normally closed relay circuit. As IGN voltage increases, the relay coil energizes magnetic circuit show with hash marks, contact pole swings to lower grounded contact. The resistors in the circuit serve as snubbers, giving the inductive current a place to go, reducing contact arcing. Inductors store current, the connection to ground actually conserves the current. In an electronic regulator, a diode provides the path, often called freewheel diode. The diode serves as an automatic valve eliminating need for contacts, cheap too. In this early block diagram of electronic regulator the diode is in a block called suppresor.
I think they were hiding the detail of diode as trade secret.
The zener diode provides the voltage reference for setpoint, other details omitted.
