Voltage regulator to field wire up in smoke

So I kind of need some help... I have a 72 charger 318 that was a no crank/no start. Put a new battery and she Car cranks like new... A couple pumps from the accelerator and runs like a champ for about 5 seconds when I notice smoke and cut the engine off. The dark blue wire from the voltage regulator to the alternator is fried and a blue wire from the resistor ballast looks like she was smoking too but not melted. Any ideas on where to go from here? I Don't have access to the car all the time "reasons" and don't want to throw parts at it that's not needed. What test should I do to find out why this happened? And is the wire from the ballast and the regulator connected?
