Yam kill switch ?

Quick one - yam 40 2 stroke . Is the kill circuit closed to stop , open to run ? (looks like that to me , but I'm doubting myself now...

Pulled like buggery on Sunday and couldn't get the thing to fire up ...( but it did last week on third pull . )

Thanks ...

Yes. Earthing the white stops the engine.

Kill Switches can be a problem, might be salt build up perhaps ? seen may people twiddling with them and then they work.

I thougth that -so its been removed ( temporatily while the boat is on the drive). I currently have two bare wires - not touching , that will be touched to stop the motor ( if I ever get it to go again) ...still lots of pulls and nothing.

I know it the engine works but just wonder if I flooded it, or the petrol connector is shot etc . Stuff works , you take it apart and put it back together and suddenly stuff doesn' work ..the way of the world !

I could be wroung but on my small merc it has to be wired to make the circuit and when released it will ground out, I would get another kill switch and wire that in for what they cost

I replaced a kill switch on my 84 Evinrude as it didn't have a kill cord. This engine was make the circuit to stop.

The switch itself had 4 terminals so that it could be made to make or break. So not all engines are the same.

Cheers all- checked it now - easy to see the plugs sparking in the dark. defo open to spark , closed ( earthed ) no spark - so its not the sparks that are stopping the engine firing .

I think I just flooded it .., or I wasnt pulling quick enough!
