Looks like a very healthy charging system I don't like the 15.0V but the old OEM spec goes as high as 15.5V IIRC
Most of the newer R/R's have a setpoint at 14.25.

I'm wondering if this is maybe the reason for the melted connectors on the headlamp, and down on the fuse box connector (the one pin that is connected to the lamp fuse within the box) ?

Candlepower has a nice ceramic replacement socket. I put one on my bike. http://store.candlepower.com/cesohb90be.html

I haven't seen 15.0v at all actually.. not sure where you guys are seeing that I wrote that. The highest i've seen with the headlamp fuse in is in the high 13s. Not sure if this means anything, but when the turn signals are firing, the headlamp is dimming in unison with the blinker

Ah, this looks like something I will be doing. Does anyone know of a replacement socket for the fusebox?
You typed 14.0-15.0. which granted is a wide range but that is what your posted.
realize even a difference of 0.2-0.3 volt readings can give a different diagnosis of state of charging system depending upon which numbers so in that regard the only advice being offered is that 15.0 is too high.
he was quoting your typing here - http://www.thegsresources.com/_forum/showthread.php?p=1272192#post1272192

Yeah yeah, simple misunderstanding. I was quoting that though.
So after a few hours of tearing apart the headlamp basket and really looking into the harness at that end of the bike .. it seems like some kind of wiring modification was done after some sort of small electrical fire happened. There is one plastic socket that appears to be original and pretty melted. All the wires except one yellow with white stripe have been eliminated going through this socket towards the accessories. The side of this socket going to the main wiring harness run stays in tact, though. Also, there is one black with white stripe wire that is loose (terminated by itself) , and two brown (brown looking -- a bit color blind i am) wires that are loose and have plastic on the end terminating them together hanging inside the basket. These three wires (the black, and two brown) come from the same run as the headlamp wires. The headlamp socket (3 wires) is pretty melty, but still makes a good contact with the bulb (i assume because the lamp is working, and switching between high and low).
When on High beam, the voltage meeter gives me ok readings throughout the basic check. When on Low beam, the headlamp seems to draw a bit more voltage. Still, I am not seeing a solid 14.4 volts at 5,000 rpm. I'm thinking maybe I just need to accept for now that with the headlight on i'm only going to make 13.8 tops on the charging end of things. Could this be normal for this year GS?
Sorry for mis reading the post, I see now you were quoting; no wonder you were having such stellar charging.
On the other hand after looking at your numbers you are barely charging. You will need to continue testing to find out.
I would do the Revised Phase A tests to see what the voltage drops are and then Revised Phase B. Sorry but you are charging but without any other equipment to test with you are faced with a process of elimination.
Charging at low 13's is not normal either the load is too high or your stator is going out (your tests confirm it is not the battery).
