Blowing voltage regulators

67Dart, It's not coming out of the alternator it's just sitting on top. I think it used to be the temp sensor which has a different wire now.

I also ran a wire off the connection at the resistor in order to get 12V to the the carburetor's automatic choke. That wouldn't change the voltage at all but it would split the current between the carb and the regulator/field. Could that mess it up?
