Electronic ignition upgrade / voltage regulator question

Seems to be a little mis-information on this thread.

Whether you have an early system with a mechanical regulator or a latter system with the solid state regulator they both just act as a switch to turn power on and off to the field windings. In either case they are designed to keep the battery voltage in the 13.8 to 14.1 volt range. Approximately 1-1.5 volt over the nominal 12.8 volts of the battery is necessary for current to flow into the battery and charge it.

The only explanation I have heard for the need of an electronic regulator that passes the common sense test is that the mechanical regulator creates more noise in the electrical system than a solid state regulator. The thought was this noise could interfere with the operation of the electronic ignition module.

The stock replacement regulator for pre 69 charging systems from Wells that is available at most chain parts stores is a solid state replacement for the old mechanical regulator. Its easily identified by the case being only 1/2" thick.

The MP regulators that are advertised as constant voltage regulators do not work any differently than the parts store regulators. They maintain the battery voltage in the 13.8-14.1 range.
