I still havent got it going but I can now turn the engine over but it doesn't fire. I have worked my way backwards from the starter motor. and it appears I havent got any power under the relay. Using 30 and 85 there appears to be no life. I refered to Miscellany April 2010 page 25 Andrew Hurst article, with the ignition on I can get no light and between 30 and 86 no light as well. But between 30 and 87 the engine will turn. I have tried a new relay and it still doesnt work. Any suggestions most welcome.
