Corrected CB wiring diagram & switch contacts' matrices

[e3steve]

Clearly you understand this stuff, and it is really helping me, one step at a time. I don't understand these points;

No problem Ken; here to inform.

in position 2, the red connects to the black and the brown connects to brown-white but the brown and brown-white do not connect to the red. how would the power get to the brown and brown-white?

A few years ago I over-drew and coloured-in the Honda wiring diagram(s) in order to help make them easier to follow. So let's do so:

• The fused supply leaves the battery +ve pole and, via the ign (combi) switch, joins with the black(s); the black(s) feed the ignition circuit and all other consumers, including the lighting switch (terminal IG).
  
  When the lighting switch is operated (in either direction), terminal IG joins terminal ML (green) which, in turn, is sent back to the ign switch and joins, in your switch's case via the now-linked brown/white & brown, to the parking light and taillight.

the harness is separated a bit, so that i have two harness elements present at teh switch
the following wires to available to connect to the switch:
one contains only a black wire that goes only to the coils

...OEM "harness 'A' " (ignition system harness)

the other harness has 1) another black,

...OEM "harness 'B' " (lighting switch, horn, starter, brake light switch, neutral light)

2) a green,

...switched return from the lighting switch

3) a 'thickly insulated' white which appears to connect to the rectifier,

...possibly a PO's rework

and 4) another white which connects to the tail light and i don't know what else

...front parking light.

The original setup had a thickly insulated white non-fused wire from the battery connected directly to the brown-white switch terminal. In position 2 that would connect the brown terminal to everything else on the bike except the black wire to the ignition coils, so everything got power from the brown including the rectifier. Should i now connect the battery directly (through a 25A fuse) to the 'thickly insulated' white wire to the rectifier?

...Yup.

The wiring diagram is confusing to me in this respect. it shows a red-white unfused wire from the battery connecting to the same terminal as the fused red wire and also to the rectifier.

...Nope. Look again, mate. Red/white from battery +ve > terminal CH (remember, the 'dumb' terminal) > rectifier.

this has really helped. i now see the r/w to the CH. thanks. Not done with the fixes yet, but one more question. I don't seem to have a front parking light. Sealed beam headlight. Where would it go? I can't find a white wire in the harness inside the headlight shell.

Not fitted to all markets' variants, Ken.

Glad my ramblings have helped here. ;-)

I owe you a pint. Do you prefer the Rising Sun, the Ferryman, or the Silver Fern.

LOL, Ken! The Rising Sun please. The other two are practically youth clubs! :-/

one more - i seem to have a 4-wire lighting switch - green, black,pink, yellow. no ML terminal, green goes to the HL. would you happen to have a diagram for that?

Ah. Two-position, or three? Some markets' derivatives disallowed the possibility of riding with just the parking lights in use. Your bike has no front parking light, so I suspect that your dimmer switch also has no deadband in the centre (between Hi & Lo beam) position? Possibly even has no detent there either? I've no experience with the 4-wire type, but my logical side dictates:

• Black - IGnition switch fed 12V supply
  Green - HeadLamp feed (to dimmer switch and to combination switch, terminal HL)
  Pink & Yellow - stator coils (these are AC, pre-rectifier, and switch-in extra stator coils to boost the charge rate when the headlamp switch is ON)

Hope this helps.
