Odd light problem
The other day, I rolled into a motorcycle store to browse around after returning from about a hundred mile ride. Some came up to me and asked if I knew my bike was on, as the headlight was on. I was about to chuckle and tell him it couldn't be me, as I had the key in my hand. Turns out, the headlight, running light, and oil light were all on.
The engine ignition and starting circuits were off, and none of the turn signals did not work though, and, so the key shut off the motor and what not. I unpluged the ignition switch, and found no change.
I looked around in the area for shorts, and found none.
I ended up suspecting the regulator, so I swapped it out with one that didn't charge the bike, but did otherwise function. The lights functioned properly. I replaced the original regulator, and the lights again functioned normally. The problem seemed to have resolved itself.
