Hey, my first post here. got 1981 XS 650 and I recently burned out the main fuse when a screw came loose from the generator brushes. When I discovered that problem I replaced the screw and got it running again but discovered that the head light circuit was dead. I suspected the reserve lighting unit so got one on ebay but no dice. Also tried connecting the blue black to the blue yellow to bypass the RLU but nuttin. So I went over the wiring diagram to try to track the problem and saw that a yellow wire comes from the generator to the safety relay before the RLU. Any ideas on how to test where the problem is? Thanks
