I'd say it is either the regulator or the resistor bypass relay. If you have a voltmeter check and see how much voltage you have at the coil on the + terminal. If it is about 12v then it is in the bypass circuit, if it is lower then it would be somewhere in the rest of wiring for the running side and the reg is the most likely suspect.
You could also check by disconnecting the resistor. If it stays hot at the points, it is in the resistor bypass. You might want to check to see if the fuel pump remains running too.
