Did you get anywhere on this?
Couple of questions: What amperage alternator and what is this crimp you speak of?
Poor crimps on high power circuits can lead excess heat and corrosion causing failure at the crimp point. If the crimp is bad enough to cause a voltage drop across it, moving your exciter wire to the choke would have only made the problem worse. The alt would push it's output voltage higher to make the voltage from the dash 12v. Possible burning out the alt faster that way?
