Anyone Running A Mechanical Voltage Regulator 67 Dart 273 2bbl

That is called isolated field. We often see members upgrade to the higher output isolated field alternator then simply chassis ground the other field terminal rather than complete the upgrade. Makes no sense to me.
I upgraded my 67 to isolated field system with used parts and about 8 feet of new blue wire to complete the upgrade. Never new there was a issue with that solid state regulator. No indication shown in OEM amp gauge needle. When I changed it to a volts gauge that needle vibrated like crazy. New regulator cured it.

That may have been one of the reasons volt meters weren't included in cars until the era of solid state regulators. Its distracting and looks like something is wrong.

In another thread Kit explained the reason Chrysler went to the ground controlling regulators and isolated field alternators.
The electronic regulators were low side switched because in the early 70's NPN transistors were more reliable and cost much less than PNP, necessary for hign side switching. The old style electronic units became available in the late 80s.
