Jonsered 2051 turbo

[Saul]

Good evening all i need help with my new project if you will.I have just bought a Jonsered 2051 from a car boot sale and the wiring is in a mess.The kill switch did not work so i took the rear handle apart to see what the problem was.The wiring has disintegrated.I now have a blue wire from the coil to the switch but it has been parted and the two ends joined together with a ring connector and it is bolted to the saw there is one short black wire from the coil that is attached to the saw.There was also a red wire which was not attached to anything which ran parallel to the blue wire under the pull start cover, this wire had a cover on the end.The switch also has a black wire but goes nowhere and has no connector on the end.I understand that the black wire from the switch must connect to something to make the circuit but i am at a loss as to where.help please.
