On the last ride I noticed the headlight on my KTM 640A was off. Went to fix it today. Here are my observations: It is not the light bulb, that it fine. The high beam is not working. The taillight is also off. The 10A fuse (#5) of the lights circuit is fine (the obvious culprit, but not in this case). The rear break light works, and all other electrics (blinkers, starter etc.) are working fine. With a quick inspection I can't see any loose wires. Any idea what might be going on?
