BS AU7 wire colour question

[PEG]

There should be no need to adapt to anything, there's a cable colour for everything. It's when people go using the wrong coloured cables and/or don't label them properly that problems occur.
As a keeper of landrovers I know all about bodgers with their bits of speaker wire and scotchlock bodgeups.

If there was no need for anyone to "adapt",i,for one,would not have earned a living over all these years. That's from a man who fitted a Mercedes 306D in a series IIA at the age of 17. It was Ex MOD and no,the wiring matched nowt:sweatdrop:

I have allocated a colour to every wire now, but I can't agree with the statement that there is a colour for everything within the British Standard.

There doesn't appear to be one for a tachometer fed from a contact breaker - I am intending to use black/blue for this function, which is the colour for one of the wires normally used to supply a tachometer from a generator, so a little adapting, or substitution, will be required.

The 2CV also has a wire from the hazard switch to the flasher unit - I am told that this is peculiar to Citroen, because of their own switch design, and, as a result, there isn't an allocation for that connection.

i suppose that one could say that there is a colour within the British Standard for every wire - except when there isn't !

Hi John.
I have only joined tonight so if you haven't got sorted here goes un-fused ignition feeds are white I have been an auto electrician for 30 years and remember the British colours well, If you need any others just ask..........Neil:clap:

Thanks Neil, completed the drawing now.
i have access to the BS at my local library, but for some reason, I had managed to sort everything out except that one - it seemed that the more I looked, the less I managed to see, a bad case of "the wood for the tree's", I think!
thanks once again

I wouldn't have thought a French Citroen would be wired to British Standard AU7 or am I missing something

 

[Sprag]

Ah!
this is because it's a very British Citroen - he is named "Ethelred", and is a "limper", that is, he only has three wheels.
if you google for Pembletons, you should end up on their forum - if you look on the chassis register you will see both four wheel and three wheel versions - mine is number 39.
all will then be sparkly clear!

I bought the Haynes car electrical manual many years ago and that had a full list of the British wiring colours.

A good supplier is Vehicle Wiring Products and I found their non-adhesive loom tape much better than using normal insulating tape for looms as it allows the loom to be flexed easier.

I had an ex who made wiring harnesses at volex,the tape they use is only about 10 mm wide,shame really because when she found out I was a spark she offered to get me my tape for free,trouble was it's no good being so narrow.mind you life's full of dissapointments,my ex wife was a very slim blonde and earned her living as a stripper, unfortunately the stripping involved cooked chickens in a factory,still on the up side there was no waste when we had one at home.lol

Hi John.
I off line for a couple of days

If you need to be correct the Tacho wire should be white with black trace.
