Another 'won't start' post but I have tried...

Thanks for the replies folks.

BLue/YeLlow wire (not BK) on 5 prong starter relay. That's the wire that has no power but all the fuses are intact, so I'll investigate that more thoroughly.

Eng management relay shown in this diagram is 4 prong and that's what the bike has.

I see that #5/87A tuns headlight and heated grips off when starter button is pressed.

I am assuming that without power to 30 that your headlight does not work?

Not sure now, l wasn't paying attention to it. But that is a good question.

Update - after all that, it WAS the clutch switch. I'd removed it and its rubber cover a few days ago and cleaned the blackened contacts but apparently did not reassemble it correctly!!!
