OK it seems that I may have not explained this wiring completely. My article lists, of the two kill wires, one goes to the kill button & the other to ground.

To further explain, of the bundle of 4 wires coming from the powerpack, the Orange/Green striped & Orange/Blue striped wires go individually to the appropriate coils. Of the other two black wires, one is grounded (usually under a coil bolt) & the other goes to the kill button.

I will ammend my article if this helps

The shorting switch has two wires: the solid black one leads to the engine ground at the #2 ignition coil; the black with yellow stripe wire leads through the three wire amphenol plug to the powerpack.

Pushing the shorting switch grounds the powerpack, preventing the ignition from firing.

According to the manual, this is the same on both electric start and manual start engines.

Re: kill switch on 9.9 Johnson 83y

so if i pusch shorting switch it does nothing. so powerpack is not groundig.so there is something with yellow/black cables which leads from powerpack and conector to the switch and back to the grounding between coiln#2 nad coil#1?
so there is place where i should look for?
i schould add that the 2 cables with shorting switch has 2 black cables.on manual i can see that on should be black with yellow

It doesn't matter if the second wire has a stripe or not.

If you connect the two wires to each other near the switch the engine should stop. If that works, replace the switch, if not, check the wiring.

Re: kill switch on 9.9 Johnson 83y

i will try tomorrow and reply if ithis coneting cables will work.
i did this post becouse i'd like to prevent my powerpack nad coills from my underskill repairs.this engin is quite new to me.i bought this engin in lost mounth and after 1 mounth of use i had to take out powerhad becouse water inlet gromet to the block was locked and did blockage to water circulation.
i also replace head gasket(head was wraped obout 0.5 mm between bolts holes),replace termostat with all termostat cover gaskets).
this overhiting problems did problems(20puls or so) with staring warm engin-when cold starts easily, but when gets warm it was dificult to restart.
did carb rebuit,some paintings.
now it has good compresion and starts very easily.

Make sure your connection (ground) is clean and tight. If the kill button doesn't work you can remove it and the front rubber will come off. Then you can take a wire brush and clean the contacts. That should do the trick. It would be handy if you had a meter and then you could use the meter to look for your problem. I've had to clean the button contacts a couple of times and the switch will then work. If for some reason the switch is not repairable, I would suggest you replace it with a lanyard kill switch, made by Seadog. It will be cheaper than an OMC button and the operator will be much safer form here on in. To be honest even if you get it working you should consider the lanyard. Best of luck. Rick.

Hi.
I cut of the shortening switch and conected cables that goes to switch(screw it up) and engnin starts and run normal way.
it mens powerpack is graunding all the time, but enigon runs.
tomorrow i will cut of grounding cable before rubber conector and will try to avoid this conector to go right to groud and check if engin will start.
my question is:this problem can be becouse something is wrong under flywheel?

Re: kill switch on 9.9 Johnson 83y

Well there is no way it should run with those wires spliced together. You better pull the flywheel and see if you have a broken wire under there. Rick.

Re: kill switch on 9.9 Johnson 83y

Unless you have a different motor this has nothing to do with what is under the flywheel. You either have a shorting wire that is not connected properly or you have a bad powerpack.

Well, I ask your forgiveness. I thought the one wire originated from under the flywheel. Thank you ezeke for stopping my misinformation. It is nice to have such depth in this cyber garage. Rick.

Re: kill switch on 9.9 Johnson 83y

grounding power packi before round conector im going to check what response power pack will give,and check conector.
i thought if power pack ib bad so engin will not have spark.
is there any way to check power pack?.
is there any parts under flywheel shortening is not working?
can anyone describe funkction all cables coming from fllywheel to powerpack?

if it will come that is realy broken, my question is if powerpack mounted on 4 4.5, 6, 8 hp models will fit to 9.9
