Headlight switch cb500 missing black wire?

[Festman]

Hello!

I´m confused. When I look at the wire diagram for my cb500 -72 it says that I should have a black wire that go to the dimmer switch. When connected to the white cable I should have low and connected to the blue I should have high light.
When I opened the switch all I have is one blue, one white, one brown/white and one brown/blue. I do have a black wire but it´s connected to the killswitch.

Any ideas?

Interesting. Possible that someone made changes? A brown/blue wire is usually used on the 360s for the wiring run from the fuse box to tail light switch (which isn't really a switch, don't get me started)...

Colors aside, what's the problem you're having?

When I bought the bike it was in pieces so I have never had it running. I thought I´d make my own harness and then i noticed that the cables where different from the diagram. But I have opened the headlight switch now so I know that the brown/blue is instead of the black cable.

Until something isn't working, I wouldn't worry too much about the color of the wires. You should be able to use a multimeter to test to make sure you have power in the correct location and you can also use it to test which switch is the input for the dimmer.

Here's an easy to use wiring diagram for the 500s: http://oldmanhonda.com/MC/wiring500.html

Let's you turn different circuits on and off to be able to trace wires easier.
