well here's my findings today. I took a volt meter & connected it to the battery positive terminal & then the ground wire in the headlight connector & I get power. there's 2 unplugged leads inside the headlight housing probably never used & one is hot. I tested that with the ground inside the headlight plug & I also get power. there's 2 red wires that go into the plug with different colored stripes on them obviously for high & low beams & they are totally dead. when I jiggle the high/low beam switch I get nothing. if the switch were corroded I would probably get intermittent operation if anything. the bike sat covered in heated garage for many years so I would think the switch is ok as all other switches work just fine & everything else works fine, but I did discover something today the self cancelling turn signal feature doesn't seem to work. I had 2 other bikes before & that feature on those bikes also didn't work. the 2 red wires that come out of the headlight plug go into a small harness which goes into the dimmer switch & there's other wires that come out of it. it doesn't look like there's any wiring damage between the headlight plug & dimmer switch, but I can't see what's under the fuel tank as they all go under it to the back of the bike.
i'm not sure which blue wire your talking about. there's a solid blue wire inside the housing & then I see part of a blue wire with a white strip running inside a wire loom & then it disappears under the fuel tank.
