Johnson 50VRO 1987 Motor will not stop after "switching off.

[glastronomic]

First of all, Thank You for this most informative forum, been "lurking" for a while.
I could do with a little bit of advise, please.
I have a 50 HP VRO Johnson 1987 outboard that is running very nicely.

It has one "problem";
It does not switch off after turning the key "off"
It used to switch off if the engine was not at operating temp or after a while running with the key turned in "off" position.
I replaced the starter solenoid but it made no difference.
On my CDI there is a separate brown wire with a bullet connection coming from my CDI (sepate from the "wiring harness) that is not connected to anything (engine is running fine with this disconnected.
Could someone please inform me what this connection should be connected to and if this is in relation to my problem.

(Ignition Kill Circuit)
(J. Reeves)

A Black wire (ground) should lead from the powerhead to the powerpack. There will also be a Black/Yellow wire leading from the powerpack to a raised "M" terminal of the ignition switch. To complete the circuit, there will be a Black wire from the other "M" terminal of the ignition switch to ground.

When the key is in the OFF position = The two "M" terminals are connected,. effectively shorting/killing the ignition.

When the key in ON position = The two "M" terminals are not connected and the ignition is engaged.
