I built a 1971 Triumph 650 bobber. I rewired it all to negative ground with Boysen electronic ignition and a electronic regulator/rectifier. I also run a battery. The only loads I have are a 12V Bates headlight and a LED read/brake light. While riding it last week the engine started to miss. It got worse then quit. There was no power to the lights, which made me think it was a fuse. I checked the fuses they were fine, I though the stator quit, but the battery was charged. I got it home, checked the connections, cleaned the grounds. When I turned the key on, the lights go bright, as soon as I kick it over they dim, then slowly come back to full brightness. I disconnected the stator and the same thing happens. It did fire for a second then died. Any help or insight would be greatly appreciated.
