Spraying ether to start

[Joker2]

went down today using my Seloc manual disconnected the Black Yellow single pin plug at the power pack, engine started right up and ran fine, I couldn't stop it unless I plugged it back in. Unless I am reading the book wrong ( which very well could be ) this means either my Emergency kill switch or my ignition switch is bad correct? Can anyone verify this for me?

Three quarters of the time the problem is not the switch itself but the devise on the lanyard (whatever that is called) that is removable in a man overboard situation.
With age it tends to warp just enough to cause the switch to activate.

And yes I think you are on the right track, ignition switch or kill switch problem.
