Voltage Regulator Issues!!!!!!!

The harness is simple. If the car runs, there is likely NOT a short. What you have is three wires

1....The output wire goes from the alternator, through the bulkhead, through the ammeter, back out the bulkhead to the battery.

2...The green field wire is one wire, and only has two ends. One end is the alternator field terminal, the other end is the VR field terminal (screw terminal)

3...The blue IGN terminal (push on terminal) is branched off from the "ignition run" circuit.

So if you jumper the blue and green together, you are running full 12V to the field / brush terminal. you can hook that up and check voltage at the field terminal.

Now I'm baffled! I recently noticed that my headlights ( and maybe tail lights as well) pulse / flash on and off and can't figure out what to start checking! When I bought the car ( 69 Dart Swinger) it had this alternator in it, which looks like it's a 70, and charges high ( about 16 V) at higher RPM and goes down to about 14.5 at lower RPM. There are two "field" terminals on the back and the battery output, but wires only going to the output and the terminal at 12 o'clock. Is this wired wrong? What else should I be checking? The guy that I got the car from did a lot of pretty mickey mouse stuff so nothing surprises me!
