    1980 cb750K A, need schematic

    I am trying to work out some issues with my electrical system. I downloaded a manual from this site but the full schematic at the end of the electrical section is not legible. you can see the lines good enough, but you cant read any of the text. so you cant see any connector names, or wire colors. i may have to buy a hard copy, but I would rather spend the money on parts.
    please help

    It's the 650 SOHC but it is about 98% the same as the 750 DOHC. The 650 uses the exact same ignition system and alternator. Honda uses pretty much common wire colors too on all models.

    thank you, I will look it over tomorrow. I am working on my turn signals. the schematic you sent me shows them having a frame ground. do you know if my 750 has frame grounds on the signals, or wire grounds? it looked like mine has wire grounds, but I am not sure
    thanks again

    There is a main frame ground that the main ground wire goes to. Honda grounds are medium green in color usually. The turns wire ground, the harness then leads to the main ground.
