Yamaha 15 wiring

[HunterSonata]

Can enyone help who has a wiring diagram for a Yamaha 15 electric start?
When I turn the key all has gone suddenly dead!
What are the colour codes for the wires which activate the electric start solenoid?
I have checked all main power feeds & earths to the engine but the solenoid no longer activates & I am trying to identify the relavent wires from the mass of colours between engine & key switch!

I don't have a diagram, but often it's a neutral switch that stops a starter from operating,sometimes there's two: one on the engine, and one on the control lever assy. It can be just control cable adjustment has slipped.....
