High Charging Rate. Found Voltage Drop Need Guidance Please

The car is a ’65 Valiant with Mopar electronic ignition Distributor and ECU. 2 pole ballast.

Warm idle the charging rate is 14.8-14.9. At RPM is bouncing >15 but < 16.

The blue wire to the regulator receives battery voltage from the ignition side of the ballast resistor.

Battery at rest= 12.6

Ignition on RUN:

Battery= 12.4

Ballast Resistor Ignition Side= 11.6

Ballast Resistor Run Side= 5.4

Regulator Blue Wire= 11.6 (Does explain the over charging condition!)

I pulled the connector to the ballast resistor ignition side. Battery voltage at the connector wire is 12.35 and 12.35 at the regulator connector wire.

When I reconnect to the ballast resistor the voltage drop is again evident at both the ballast and of course the regulator.

I installed a new ballast resistor. No change to readings.

The only modification to the wiring is the addition of a third wire within the ballast ignition side connector that routes to the ECU.

I would appreciate any help/guidance from the FABO electrical gurus.
