Accurate cb550k3 wiring diagram

[nairb]

Is there such a thing as an Accurate cb550k3 wiring diagram for a 1976 550K3.  I have what I believe is a 1976 550K3 from new.  BUT I needed to look at several wiring diagrams to fine one that almost fits the bike.

The Haynes manual fits the best (shock)and thats for the cb550F.  The strange thing is.....when I ordered some new throttle cables for a cb550K3 a while ago from dss they did not fit...... In the end a CB550F throttle cable did.  I have long wondered if the bike I bought new from a shop in Peterborough was actually an F1/F2 disguised as an K3.  It was the last year before the cx500 arrived in the showrooms and I suspect the bike shop was keen to be rid of the old 550's.

I have not heard of a 1976 K3. K3 was from 1977 on. Anyway, here a link to the Shop Manual CB500-550 which contains addenda for the CB550K2 '76 as well as the K3. Wiring diagram K2 is in p.172, K3 (three different diagrams) are in p.182-4. https://www.dropbox.com/s/88zdzlj8olqi8pl/Honda%20CB500_CB550%20%20Four%20Service%20Manual.pdf?dl=0

I have a digital copy of the k3 suppliment which has 3 wiring diagrams, if you want i can email it to you. The f models have a junction box under the tank where as the k3 many wires join in the headlamp, so quite different.

Mmmm, I thought it was a 76 model.  Or I thought I purchased it in 76.  So I managed to dig out its invoice from that time. See below.

And it plainly says 20-01-78.  So there we go.  And it does say New CB550K3.  Funny how the new clutch cable is to long and the K3 throttle cables dont fit.  Maybe I dident get the right ones.  The frame/engine numbers are correct for a k3.

The European type wiring diagram seems to be the one.

Does the swinging arm have closed ends or removable blocks?

Just checked... they are  removable blocks.

It had 4-into-4 exhausts and looked like a K3 when it arrived.

It was "Ken Ives(1975 Ltd)" of Leicester, anybody remember them?? from years ago, who thought it was a re-badged F1/F2.  Anyway its been to Italy twice and Paris 3 times in its younger days.  So whatever it is, its done good and never broken down - except for a puncture or 2.
And now its finally back on the road.
