Gentlemen, once again I beseech ye.
Will a kind soul please tell me, the one who is supposed to be an apprentice electrician, just how the headlights are supposed to work?
From what I can gather from studying the schematic:
When the engine has been started and the CDI-box senses that the stator is generating sufficient power, it will energize the coil of the load control relay, sending power to the 20A fuse labeled "C". The fuse feeds the high beam switch and the top side of the NO contact of the high beam relay through the Light blue/White wire. Assume the low beam is active. The light switch is conduting power to both light bulbs through the green wire.
Hold on to your hats now, this next step is what throws a sixteen inch crescent wrench into my spinning primary clutch:
While the low beam is active, as earlier assumed, the power is not only sent to the low beam side of the bulbs, oh no. The power is also sent to the coil of the high beam relay, thereby activating it. But oh no, now both filaments of both bulbs are on at the same time, according the the schematic. However, I know with 96% certinty from looking at the actual light on the snow in front of me that the light switches according to the rule of "OR". High beam OR low beam, NOT high beam AND low beam. Low beam sends a lot of light near the sled, and high beam sends alot of light way far out in the distance.
Let's complete our work-through of the schematic. We will now assume that we are running on the high beam. Voltage is not present at the lower end of the light switch, thus the green wire is dead, the low beams are not lit up. Voltage is also not present at the top side of the NO contact of the high beam relay, and as such, the NO contact is not conducting power to the high beam filament. In conclusion, there is now no lights when the switch is in the high beam position. From simple observation, I can proudly say that this is not true. As delivered from Iwate, Japan, the sled will switch low/high, not low and high together at the same time and then nothing. I'm missing something while looking over the schematic, but I just don't see it, and because I just don't see it I will go ahead and assume it's a blatantly obvious and completely stupid near-insignificant little thing.
The reason for my sudden and unexpected interest in this topic is that I have retrofitted a pair of Morimoto Mini D2S bi-xenon projectors in the headlight, but I have no high beam, even despite spending several hours out in the garage, throwing mystic rituals w/ frenzied dancing, sacrificing goats on the altar of Ohm and cursing at the blasted thing.
We love pictures, so I grabbed one from the manual to illustrate the issue:
