I bought a 31 year old KE100 earlier this year with only 800 miles on it- great condition. I was teaching my Dad how to ride yesterday, and the headlight stopped working (I noticed today that the tail light also doesn't work). Prior to yesterday, all electrical stuff worked (not sure about the dash light- haven't checked it). Today, when I turned the ignition on, only the Neutral light comes on. If I start the bike, the horn, brake light, and turn signals work, but the low beam, high beam and tail light don't. I looked behind the headlight, and the wiring actually looks unmolested (thankfully). I used a meter and saw that there's no power to the headlight and also the tail light. The fact that both of these are out at the same time makes me think it's something simple. The bulbs are fine, and so are the fuses (although I replaced them, since they looked 30 years old). Any ideas? You guys are much smarter than me, and I'm an electrical dunce.
