I can idle with headlights on high , fog lights on after-market driving lights on and my Fluke meter reads 13.98 volts. What an amazing upgrade.

... not sure of the need for this step.
the alternator is attached to a solid aluminum bracket, bolted to the block, and there is a large copper braid connecting the block to the body of the car.
this would eliminate the possibility of a voltage drop from the battery to the block through the body I suppose...
certainly if charging issues are happening, adding an additional ground to the alt frame could help. as could cleaning all the existing connections, and brackets.
Hmmm...
