    Hi All

    My brother is rebuilding a Honda CM125 that he dismantled many years ago.
    He labelled the wiring loom but now the labels have faded and he is not sure
    where some of the wires should go. He has an Haynes manual but the diagram
    is black and white, so is not clear to him what colours go where. Does
    anyone know of where he can view a colour wiring diagram, or does anybody
    have a CM125 who could answer his questions. I am hoping to introduce him
    to "Newsgroups" so he can ask himself, in the future.
    Many thanks for any help.

    You might do better introducing your brother to the wiring colour
    codes in the Haynes manual, which enable use of a black and white
    diagram when referring to cloured wires.

    Is a colour version available?

    My brother has recently purchased a new manual which has a black & white
    diagram. Is this an old copy?

    So the pingfuckit you've just spent an hour searching magically pops
    out of the corner and slides back into place. Works for me[1].

    To be honest, I have only seen a couple of full-colour wiring diagrams
    and they were both in manufacturer's own manuals.

    Every Haynes manual I have seen has contained black and white wiring
    diagrams of varying quality, completeness and usefulness. However,
    every wiring diagram I've looked at has little tiny lettering on or
    alongside each wire. This is a code, the key to which is supplied at
    the base of the page or sometimes on the next page.

    For example, "bk/gn" means "black wire with a green trace"
    Or "bl/r", which means "blue wire with a red trace"

    Am I making sense yet? Go check the diagram and its environs for a
    code key and hopefully all will become clear.
    I wouldn't think so.

    Probably, and you'll probably find that the colour wiring diagrams in
    the new Haynes manuals[1] are rather useless as well.
    On closer inspection of the B&W wiring diagram you'll find that the
    colour codes are noted beside every cable. So get your brother brush
    up his reading skills and reassembly should be the reversal of

    Oh, and another thing - please have a look at the FAQ for this

    newsgroup. Please leave *some* context in when you're following up

    That would be fairly feckin' miraculous ime - if the valve retaining
    collet could bestir itself from the bramble entanglement out the back
    of the garage, levitate ten feet and hurtle back into place through
    the neat hole it made through the asbestos roof ... I'd go and light a
    candle. And pay for it too ;-)
    No, that's just you, Timo. Tou have the reverse Midas touch, see -
    everything you contact turns to shit, in short order.

    Neither did I. I just figured I'll have a quick look before I make
    myself look even more of a twat. Imagine my surprise when it turned
    out to be true.

    Mind ewe, the wiring diagrams these days are becoming rather useless
    for tracking down anything worse than a chafed wire. For any
    ignition-related problems one needs to drag a computer into the

    Bloody 'ell. I didn't know that. All my BsoLs are old copies, then.

    Heh. The "dripping with sarcasm" part of my lines above seems to have

    Thanks for explaining my life to me, mate...

    I still hope that I'll manage to break free of this eventually, but
    judging by the way this is going atm I'll be arriving for my own
    funeral on the back of an AA lorry because the undertaker's cage broke

    Hi <Bear mode> read the FAQ`s.

    Then in the morning when I`m more sober I might put a complete colour wiring
    diagram on my site and give you a link to it a CM 125 C
    between 1977-1983?

    If not I wont bother scanning it.

    problems? Speedometer problems?

    I've got Haynes manuals for Dreams and Superdreams which predate the
    CM125 by a bit, but are most definitely colour. The Haynes manuals for
    my more elderly British bikes are b/w.

    Unfortunately (in a way), we sold Dee's CM125 a few months ago, so I
    can't be much help. I'd say it's worth looking for a Haynes manual
    with a colour diagram though.

    My Haynes manual for the CM125 printed in 1984 has a colour wiring diagram.
    What do you want to know?.

    The Haynes manuals for my MZs, BSAs, Guzzi and the other bikes are black
    and white. TBH I've never seen colour diagrams in Haynes manuals. Car
    or bike.

    MZ factory manuals OTOH...

    Thus spake Pip unto the assembled multitudes:
    Try owning a Vauxhall, where the wiring colour codes are marked with
    German colour abbreviations, just to add a little extra adventure to
    deciphering black & white wiring diagrams.
