Pioneer chainsaw: kill switch problem

Hi I have a p41 saw made in the 1980s I replaced the cylinder and piston, the kit came with a new flywheel and coil the instructions said they had to changed for the new cylinder,after installing them the on / off switch no longer works the saw will start with the switch in the on or off position it will not shut when you put the switch to off.
I checked the wires and they are all connected none are broken.
Not sure how to test the switch only has 1 wire going to it. When I pull the wire off the switch and ground it to the metal housing the saw shuts off. Not sure if I have something wired wrong?
Maybe someone has some ideas,a wiring diagram, photo from an original p41.
Thank You for your help.

In order for the switch to actually kill the engine it needs to complete a path to ground. It can't do that with only one wire.

Either that switch itself must be grounded or you may be able to take a wire from the switch body to the metal engine frame.

If you are unsure of the switch you could post a pic of the wiring terminal side.

Make sure the switch makes good metal-to-metal contact with the frame.
