Unplugged wire
« on: April 23, 2012, 12:06:23 PM »
New bike, new problems.  1976 cb 750.  Under the left side cover there is a green wire that is not connected to anything. Any thoughts on what it is for?  Also in my headlight bucket there is a black w/red stripe wire that is cut and taped off so it is no longer connected.  Any ideas on what it goes to?

Bk/R is high beam switch and green is earth. The green wire may have been connected to the rectifier mount.

Man, this post is timely.  I was just looking at the same unplugged green wire on my newly acquired bike yesterday trying to figure what it connected to.....   I was going to take an image and post the same question.

Thanks for asking!!!

Cheers,
Pat

Might be for the flasher-some types need that extra wire-it'll have the same connector type as the flasher.

You're correct.  The US models came with 2-prong flashers and didn't use that ground wire, so it's just an extra.
