Overcharging

I have the same problem of overcharging. I have changed the amp gauge to a voltmeter. Also have a MSD ignition, so I do not have a ballast resister, I installed a terminal strip with the wires are connected to
What I am seeing is you start the car the voltage is 14, but when you increase the rpm the voltage goes to 16.
The test from the battery voltage to the Bark Blue wire has a 1.18 volt drop I have 11.6 at the strip. So I have a voltage drop in the ignition circuit somewhere.
My general question is if I am taking volts from the same place: to the regulator and to alternator, no matter what the volts are, should the regulator still work properly? Or does or get the difference from the battery side of the alternator? or from a voltage drop in the ignition side?
I am still chasing things down, this wiring has been butcherer way too much over the years.
