I've just been doing some more tidying and now just have a couple of issues where the loom serves the back of the dash. This is what I've deduced by doing some continuity tests.
Can anyone confirm the following to help avoid a fire?
Two wires (one brown, one red) - Ignition switch.
Red/white - starter switch to starter solenoid.
Red - connected here to voltmeter +ve
White/black - tacho signal.
White/brown - Oil pressure light switch.
There is a red wire which emerges from the harness at the front of the engine next to the white/brown oil pressure light switch wire. It isn't used here, is it the other end of the one on the voltmeter? It may be broken in the loom as it doesn't seem to be continuous with anything the other end.
In future I will make sure I have this information to hand before disconnecting the bloody lot all in one go to make cleaning easier!
I think a hard copy still exists, not sure if it's electronic.
Why do you need it Brian?
So what's the problem? I don't understand. Does the wire has the label +ve on it? Was it connected before? Does the car still run? The colours you list for the other items are correct.
All sorted now thanks Steve. Everything working as it should.
At the risk of being boring... I had a chat with Paul Freeman this morning to try to identify the mystery red wire I have been talking about and he is now as confused as me. The picture here shows the wire shares an extension of the loom with the white/brown wire to the oil light switch. The extension comes out of the main loom close to where the coil is connected. Can anyone throw any light on this? It seems to be redundant as it has been insulated and I've tried to do a continuity check and can't find the other end.
That's why i like carbs, less bullshit....
Onno, that is difficult to argue with, as long as the trumpet nuts don't decide to jump down the inlet. I had that once at Thruxton and the engine swallowed its nuts and bust the valve heads off middle of Church corner at indicated 128mph... that was 'different' ...
Glad you're sorted Brian. I see the SS has removed a post again!! Hilarious is this censorship.
...it's difficult to remember BJ, because I am old now, but I believe that it was along the lines of the red wire in the photo not looking to me like a loom wire because of its dimensions and that it looked more like a wire from a Halfords reel. I think I said that you could unwrap the loom - which is of course allowed by the police- and investigate where it went to , especially as there was no continuity... I think I suggested you could re-wrap in some nice proper loom tape like wot Alex has done in the past. I believe that I also suggested (well more wondered really) that it may be a concern as to the state of looms after 20 years under the high under-bonnet temps (i.e. brittle) and that of course you could as an option always get a nice professional loom made which would weigh a fraction, be very direct, not be capable of anything inappropriate but which would currently mean you would have to race in Proto.
Also of course you could throwaway the loom etc and run a nice pair of Classic A sport carbs but then we are back to the old chestnut of losing your nuts down the damned things as well as running in Proto.
Actualy the more you look at it, the Proto lark looks like quite a good idea!
I hope I don't have to type all this again Brian!!
I don't get all this censorship absent abuse; indeed censorship absent abuse is a form of abuse. Is it because I is black?
