Anyone Running A Mechanical Voltage Regulator 67 Dart 273 2bbl

Not exactly, it is "dead band" voltage. Similar issue with electronic. The dead band is voltage range around setpoint, where switching does not occur. An example is off at 13.9V, on at 13.7V, a peak ripple of 0.2V. If dead band is only 0.002V, switching too fast to fully go on and off, heating transistor, or points.

I follow that.
Wouldn't that be controlled by the gaps between the upper and lower points, for a given coil and spring?

The dead band is adjusted electronically by adding bias to setpoint, controlled by switch state. Ever hear of Schimitt trigger gates?

No I haven't.
