I have had a eureka moment. All this head scratching, fiddling and headaches with the wiring loom has come together. The final piece of the jigsaw has been sorted out. Sorted in the sense I know where the wires go and what they do. After a great deal of wrestling I got the ignition relay bracket dismantled, cleaned and fitted back on the bike. However it took another three refits before the bracket, connectors and loom finally decided to play ball. It is cold in the garage so the wiring loom is stiff which is not helping. I am sure the stiffness is due, in part, to the age of wiring. Things will be much better when I get big cable ties to hold the main wiring harness in position. I also discovered where to route the loom round the rear down tubes onto the rear brake light. As soon as the screws for securing the brake light switch turn up and are fitted I will secure the cables to the frame.
It is odd but the wiring looms seems to be from a US spec bike. The wiring diagram on my wall has the UK and US wiring options marked. I keep coming across spares wires that seem to be for the US spec elements. The US elements just do things like keeping riding lights on. I guess as long as the bike with runs and the lights work in a UK style I can discard the US wiring elements. [touch wood]. Lets hope I do not regret making this statement.
