1967 CB450K0 Black Bomber Rebuild - By Royhall
mo goldie:
have just had a look and found this out Ash.... so hope this a bit more clear....well to you but Not me lol.
Pink at ign switch but that was disconnected.. to the stator end yes continuity there. Brown at ign to brown
at the stator and rectifier Yes to that too....Yellow at ign to stator and rectifier yes to that too.
Ign switch back on the connect yellow to pink on light switch on yes they do connect when switched to that's lighting circuit.
the thing I can`t get is that wire on the right of the block at the Rectifier which looks as if someone has put some paint on to make it look like a pink wire..... I have traced that back were it comes out of the loom beside the battery which is a pink and white.....
Now when you look at the rectifier do them wires look right to you guy`s if you look at the 1st picture that's the one come out near the battery loom.... and the 2nd picture is where it comes out at the Rectifier end from the loom... I know that it is right by the colours That we said about earlier what comes from the stator end so are they right now but at the rectifier side ? hope this makes sense to someone.

Bloomin' eck Mo ... getting confused myself now! Those old wires don't age well colour wise and sometimes you have to strip back the loom a bit to see unfaded sections. But I guess the black painted wire is the pink wire.
If it was me I would do a test to try and establish if your 5-Speed alternator is performing as it should, taking the wiring loom/ignition switch out of the equation. I would get lengths of wire black, red and one other colour and wire the alternator directly to the rectifier (with the 3rd colour wire) and then the rectifier DC output (i.e + and -) directly to the battery (with black and red wires). Connect the PINK wire to one of the AC terminals on the rectifier. Firstly, only connect the YELLOW alternator wire to the other AC terminal of the rectifier. Run the engine and monitor the volts at the battery with your multimeter switched to DC volts. If the readings are not good (i.e no significant increase in voltage when you rev the engine) then also connect the WHITE wire into the rectifier and do the same test with the multimeter. This will put the full output of the alternator into the rectifier. If you don't get a decent charge then it's a suspected faulty alternator stator. If you get a decent charge with both alternator coils in circuit but not with just the yellow wire connected then I would suspect weak rotor magnets.
NOTE !!! Colours are for your 5-Speed replacement stator and NOT the original Bomber K0 stator.
Hope this helps !

Thanks Ash
You make it sound so simple lol confused I am........ well I will have to put the carbs all back on at some point to get it running and give that a try so thanks for the drawing as I need something to go by lol.
wish the bit I don`t get my head around is the Electrics...... but I Must get it done by next month I think the 23rd as a yearly small bike show at a Pub and want to take the Honda...... pity about the carb parts tho, as the ones that are coming wont be here till end of April or into may then i will have to take them all off again to sort them out..... Not to bad tho as they were £17;99 for the two kits.... anyway I will see how things go and thanks again for all your help...you will get fed up with me with this problem as I just can`t get my head around it all.
Oh if you mean the black wire...... its the one left in the plug is brown ( looks Black )...yellow... and pink ish lol

Mo. You will probably find that those parts will arrive much quicker than you think.
