Does anybody have a 76 750 K owners manual that they could scan the wiring diagram for me?

Im trying to figure out the mess that the PO has done to the wiring and I dont have many hairs left I havent been able to find a 76 manual yet....and the few diagrams on the net are not for the 76 model. Im trying to make sure that all the wires are connected color to color....but Ive found some extra wires that dont have any matching wires to hook to them.....a single Black/Red and a single Brown.

I took the turn signal buzzer off to make some extra room........will the signals still work without it being in the system?

Also.....since putting the Clubmans on, theres is alot of extra length coming from the left hand contols.....horn,low/high beam,etc. Is there enough room in the headlite bucket for the extra or would it be best to cut off the extra and put new connectors on the ends?

One more.......I still cant get the starter button to work. The starter does work though, I can start the bike by jumping the contacts on the solenoid and the starter will spin the motor. I checked and cleaned the contacts for the starter button, traced the wires, and even installed a new starter solenoid and the button still wont actuate the starter.

Considering in 1976 There were Three Cb750 Models (Cb750K6, Cb750F, and Cb750A) it is not surprising that the harness would have a couple of leads that go unused on certain models.

I'll check my uncut 76 and see which leads you are talking about but if I recall correctly from rewiring my 1975 last year, those leads should be unconnected (unsure about the red black, but the brown I am pretty sure of). the headlight bucket should be able to take the extra wiring but if you don;t want to jam it all in there, just coil it behind the headlight bucket.

As for your starter button check two things, there is a fuse for the starter that may be blown, and also the button in the control it self may be shot. Since the starter button switch itself is usually fragile I am willing to bet that it is the culprit. Get a hold of another right hand starter button and try that out. Of course it could be those disconnected leads are for the starter also, although I seem to remember the starter button wire being green (also check the ground inside the bar itself).

Real cafe racers are kick start anyway, so you could just ditch that heavy starter.

Let me get my shop manuals, I never have them handy when I am at the computer, and I'll try to get more specific about your wiring issues.

Thanks Gee.......

I had a guy post a scan of a 76 diagram over on the sohc site but the resolution isnt good enough to see the color symbols for the wires. He did draw a basic diagram for the starter circuit itself and it explains why the starter button isnt working. The headlite is wired thru the button so that it goes out when the button is pushed. Shows a black wire connecting to the Blk/red wire which goes back to the starter circuit.

I have had the right hand control apart and the button is fine....even cleaned the contacts up and all the wires looked OK.

Still sucks that I cant make out the diagram though.....would like to get the wiring knocked out so that will be out of the way. Im watching a 76 manual on ebay....just hope I can get it.
