Others have reported that timing gears rattle with electromagnetic regulators. Directly switching 12 v to a field intended for about 4v is crude and brutal. There is nothing to prevent full continuous field current when system volts low and that should overload dynamo, although many claim no problems!
Pure musing but many 12v conversions simply wind the 3rd brush back to retain 8 amps peak charge. Unless the switching action wears the brush I do not see why the 3rd brush cannot be retained, wound back, and fed from the regulator F terminal.
Books set old regulators at curiously high volts cold. I monitor the car battery in normal runnng and tweak for about 14.2. Enables use of digital meter.
Most single coil regualtors incorporate a current overwinding which reduces output under load to preserve the original matched dynamo. With peak field current set by some other means this feature a complication.
