Overcharging 68Dart...need some short fused help (pun intended:)

Awesome pictures, better than what I found in the Service Manual.
Those are all from MTSC 66-11
The regulator tests start on this page Alternators and Regulators (Session 228) from the Master Technician's Service Conference

Here's the set up with some notes added.

Ignition wires in this case refer to the power coming from the run terminal on the key switch.

While the first test could be done with a carbon pile, for most people the way to add load will be to turn on lights and or heater fan.
Current from out of the alternator will then increase to match the demand. Volts at the alternator need to be very close to the volts at the regulator's ignition terminal or these tests are not valid. (I think you understand that but others seeing this post who have not read the thread or the booklet may not.)
