No Start and No Spark 1994 15hp Johnson Outboard

[lmjpsl]

I had the motor idling in the water for about five minutes. Then it just stopped and I couldn't get it to start again.

I checked that I had fuel flow at the fuel pump and fuel makes it to the carburetor. I bought a spark tester and hooked it up and while pulling the rope, the light does not light up on the tester. I would say that this means that I do not have spark for both spark plugs.

I read that I should try the kill switch, which I thought could be the culprit. I see that there are two wires from the kill switch: one goes to the ground on one of the screws on the ignition coil and the other goes to the connector for the power pack. I read there should be a yellow/black wire, but I do not see it. I just see these two wires and both are black.

My first question is if I disconnect the wire that serves as a ground, am I actually disabling the kill switch?

Secondly, both the ignition coil and power pack appear to be closed. they don't appear to open up for testing. How can I test why I am not getting spark with these two items?

Remove the one black wire that is the ground.-------That will bypass the kill switch.

I removed it and there still is not spark showing on the spark tester when I pull the rope. Thank you for your response.

Well you may be in for ignition testing (just guessing gets expensive -- unless you have access to a similar motor). If you have a known good CD unit, for example, it's easy to swap it out and see if that's your fix.

Search out the CDI troubleshooting guide. You can use a multimeter to check charge and sensor coil resistance. Coils are under flywheel, and you test from connector between flywheel and cd box. If they test good, you likely have a bad cd box..unless both drive coils failed at the exact same time (unlikely).

Good luck!
