Over charging now, no ballast resistor

Bypassing the ballast resistor won't have much to do with overcharging. Check for the following:

Does the alternator charge with the voltage regulator unplugged? If so, the alternator has an internal short.

Does the voltage regulator see battery voltage at its input, or is there a voltage drop? If there's a voltage drop, check for loose or corroded connections.

Does the voltage regulator have a good ground? It grounds through its mounting screws to the sheet metal. This may need cleaning. Also don't forget the ground cables from the engine to the battery and chassis.

If all that checks out, the voltage regulator is likely suspect. New is not always the same as good.
