I thought I had the wiring right on my '76 CB550F. Listened to Hondaman and found 1034 bulbs to replace the 1157 in my taillight, switched to a halogen front, and found the hi/low switch to be corroded and the spring broken in it. Disassembled, cleaned, and replaced spring. Switch felt like new, headlight worked, Hi and Lo, turn signals, tail/brake functions, just no horn. As soon as I mounted the assembly, it grounds to the handlebars and I blow my headlight fuse instantly, but my horn works. Wrapped the bar with elec. tape EXCEPT the outer collars (for case ground) on the possibility something else was grounding that shouldn't inside. No difference. Everything works except the headlight. Turn on key, blow fuse immediately. What am I missing? I should never have quit smoking cigarettes last week, my patience for diagnostics is deteriorating rapidly. I want to replace the fuses, got new holders for chip type, but this MUST be rectified first.
