I won't be getting to it tonight. I do have a multimeter already, just don't know what I'm looking for at on my bike. Battery is less than 6 months old. Bought a new one around May/June. It's definitely the charging system, whatever that consists of. Just need to troubleshoot that.

That's right! OP, the rotor is the magnetic "cap" that covers the stator which is bolted to the crankshaft. When spinning over the stator, AC voltage is generated.

It's the voltage regulator 90% of the time. That is after you you checked all connections...
12.2 to 12.7 (ish) DC volts on battery at rest with ignition off. 13.2 to 14.5 (ish) DC volts after bike is started and running. (Both measurements are at the battery pos and neg posts).
If voltage stays in 12 Volt range and does not increase when running, next would be stator output test. Switch over to AC volts on the meter and disconnect stator plug at the regulator, at idle your should be getting 18 to 35 volts ac and then it increases with the engine rpms... if not, it is the stator or rotor.
Time to start pulling the primary (after checking the voltage regulator ground....(the volts can vary a little from my numbers listed above, this is just a generic or rough guide...at work and typing just a quickee here.....YD

So I charged the battery up and had 12.8 vdc when I started it. Before I did that, I checked that plug from the reg. not only was it very loose but it appears one of the connectors is in bad shape. Pics to follow. I cleaned up the connecoptors with. Wire brush and hooked it back up. Bike started and was actually charging, about 13.7 vdc. It was going well, had it running for about 5 mins, to be sure it wasn't a fluke, when I saw the connector was smoking. Shut it down and disconnected it. Unsure what to do now. Hook it back up and see if it just had some oil between the connectors? Splice them like someone said earlier? Open to suggestions

Refer to back to post #10.
Your local auto supply will have 12-10 yellow male bullet connectors. (Preferably the ones with heat shrink).

This size will fit the female holes in the stator plug. Before you cut the bad plug off the regulator take note as to what prong/wire goes in which hole of the stator. Crimp the connectors on and plug wires into correct holes.
After testing for proper voltage/charging I coated mine with liquid plasti dip to seal from moisture and if you get creative with a mold it can resemble the factory plug.
I had one of my plug prongs burn/break on a road trip one day and the above to get home and ended up leaving it this way for years ha.
