R90 Wiring Map

charlie I like to have a copy

Gladly, Richard. I can send an email to you using the Boxerworks software but I can't include an attachment. Please send me an email or a PM with your address (just click on 'Airbear' to see options) and I'll be able to attach the PDF. Cheers.

I'd rather have the wire colors noted in text than in color. What the wires look like and how colors reproduce on a drawing are not the same. Both notations are OK, tho.
YES, it's difficult to follow a chematic that has a lot of parallel wires when the drawing is small. I enlarged my Haynes to 11 X 17 for the R75/5 and it's quite readable. some of the pictures for the various components are tricky to understand at first tho.

Jean, I wondered about whether I should include the text labels for the colours. It would be a simple addition, and I could even include the standard German codes.

I have looked longingly at the diagram for the /5. It is delightfully simple. I might run one up just for the experience.

Since we are talking about schematics, ONE of my tricks is to put the B/W print in an inepensive plastic sleeve. Then use a higlihter to trace the wire I want to follow on the plastic. That way the schematic is not ruined, and I can easily spot what I need to know.
Alternate:
A piece of kitchen plastic film stretched over the schematic mounted on a piece of cardboard, is also handy to use in the shop...Easy to read and make notes on.
IF you have a small schematic, a copy shop can make you a copy in 11><17 (my eccs key just failed!!) then use it with the plastic and it's good for a long time.

There might be a beer in there for you Charlie!

Nice workaround but Holy Sheepshit, Jean! How e'eccs'actly are you going to get by without an 'eccs' in the long term?
(Note that I am deliberately refraining from using the real 'eccs' key because to do so may cause envy and embarrassment.)

ps: my vote for the culprit is toast crumbs. It's always toast crumbs - or something that looks like toast crumbs.

Ah, now yer talking, Garnet. Leave it with me - I'll do it when that is 'The Next Thing to Do'.

Most welcome, Richard.

Further news: I've sent the PDF to 8 members so far and I'm looking forward to getting some feedback. In the meantime I've removed Brunhilde's headlight and instruments - she's getting a new 'face' (new chinese copy of a Ural headlight plus an Acewell electronic instrument). In the process I've been thinking about some changes to the diagram, particularly to do with what happens inside the instrument pod. I want to include a better representation of the instrument connector plus the printed circuit with the idiot lights in the correct arrangement.

So hold the presses, I'm working on Revision 2, which I will send to all recipients of revision 1.

Edited to add a ps: I will also include optional wiring for the Omega ignition and for a 3-pin indicator relay.
