No charging

Okay so I have a no charge situation and my brain is just not working.

I understand the wiring diagrams and I know I am not getting voltage at the regulator but I can not figure out if I should be getting from the field or ignition side. Brain is just fried. I am thinking the ignition side that being said I should be getting battery voltage correct? I should get that with the key in the run position engine off right? The wiring diagram shows 2 wires off the ignition side 1 going to the ignition and 1 going to the top of the ballast resistor. So I should get the same voltage in both places right?

Just trying to make sure I got this right because I have been fighting with everything this week.
