1971 CT1 handlebar turn signal/hi-lo/ horn switch assembly details

Hello all. Been lurking around here for some time as I reassemble this 1971 CT1. I have reached an impasse at this handlebar switch housing and how to assemble all these little pieces (I assume/hope they’re all there). I’ve looked through the tech library and searched the web and this site and cannot find any details of where everything goes. I feel certain somebody has taken apart and reassembled one.

An old drawing from an ol' friend.
Thank You DEET ! ( hope you don't mind me sharing this image. )



THIS IMAGE should be in the Tech Library !

from the UK.

I've rebuilt a couple of those myself, but always had a complete one at hand to use as a guide.

A couple of observations/comments from your photo:-

1) The housing was originally bare metal (or at least the underside was) - there is a chance that the paint might inhibit the housing grounding against the handlebars. If you're going to keep the paint, then make sure that bare metal of the housing touches the chrome/bare metal of the handlebars.
2) As well as kindly producing the drawing for RickC, DEET also supplies new silver/grey protective covering/sheathing for the wires - this is indistinguishable from the original Yamaha item. As you've already got the switch apart, I would contact him at This email address is being protected from spambots. You need JavaScript enabled to view it. and buy some!
