65 barracuda not charging PLZ help

With the starter relay disconnected, and the key in Start,
the S2 wire will be at the same voltage as the ignition switch.
With the J2 (Run) wire disconnected at the ballast resistor, its voltage will be zero.

With J2 conencted at the resistor, you very well may find electricty flows through the regulator and rotor, especially if the distributor points are open.
The current flowing through the ballast will lose voltage due to the resistor.
Some voltage will also be lost going through the VR.
