CB77 Headlight Issue

Post by Merz64cb77 » Sat May 27, 2017 8:52 pm

I am wondering if the forum could help me with an issue that I'm having with the headlight on my CB77. It was working just fine but when I unscrewed the housing to change a couple of the peanut bulbs for the instrument light it stopped working?

I also found out that the parking light is not connected and the peanut bulb for the red light on the instrument cluster is not working but I can tackle that with the wiring diagram.

Here are some pictures of the current wire configuration. The only odd thing I noticed was that the green wire coming from the dimmer switch is not connected to anything? Blue and red are.

I checked the bulb with my multi-meter and it works.

The instrument lights works, neutral light works, tail light/rear parking light and horn works.

Thanks, Merz

One of the four wires going to the dimmer switch is connected to the headlight switch. That's the brown wire, blue is high beam, red is low beam and black is the horn wire. Sounds like you have a re-pop switch and the colors are different.

Hi Mike,
I found the issue. Faulty ground connection, green wire from the dimmer switch. The bullet connector snapped. Thanks for all the help. I really appreciate it.
