Fatboy won't start. Clicking sound.

It was at 13.05 with the bike off. 12.76 when on. And hovers between 11.1-11.5 while the start button is pressed.

If that is the case then when the button is pressed you only have 10.85-11.25v.
In that case your battery sounds weak.

Everything seems to check out except for when I rev it.
While revving the bike, no change happens in voltage (stays around 12.7) According to the sticky, it should ideally be between 13 and 15.
Here's the levels I get:
Before test/Bike off: 13
Bike on: 12.7
While starter is engaged: ~11.3
While idling: 12.7
While/after revving: 12.7
After test/Bike off: 12.85
Regulator diode test seems fine. Stator doesn't seem to be shorted to the case.
Also checked the terminals and wires to battery, they all seem solid as best I can tell.
I'm fairly naive about this stuff. Not sure where to look next.

Okay, checked it. Stator seems to be putting out voltage fine. Around 20ish-30ish volts while revving the bike.
So, no voltage increase at the battery while revving, but the stator is putting out voltage.
Does this narrow it down to the regulator? Or am I jumping the gun?

Update: I hooked up my battery tender after that last attempt I recorded. Then after about 20 minutes, I tried starting again for the hell of it, and it fires right up like nothing.
I had measured the voltage before hooking it up and it was about 12.2v. So now I'm really confused.

12.2 is probably around 50%. Check your manual it will tell you. 12.7 is full.
Now the question is, it is it the battery or charging. It is a newer battery. Charging or connections.
On my vehicles, clicking in 99% not enough power. Often loose connection, or low battery.

I am going with bad volt reg, ignore the diode test Harley has. That seems to he dumb test.
You could check the ground for the volt reg, where it makes contact frame.
Harley regs dump to frame when not needed. My cycle electric does not.

You can also debate if a laod test if a destructive test. I work with 125 volt DC batteries. It is a debated topic.
