Default Wiring Diagram For Johnson Ignition

Well I purchased back my old boat to have a smaller boat to run around the creeks. It has a 1994 150 Johnson with a push coke ignition switch. The guy replaced the ignition switch and said its not work correctly sense he replaced it. I can't hear the choke kicking in and it takes a bunch of turns of the key to get the starter to kick in. He said he thought it was a bad ignition switch when he had the problem but he has replaced it twice. I figured it best to make sure its wired correctly first then go from there. I know I need a manual but he is looking for the one I gave him when he purchased the boat.

Does your ignition switch use the 6 pin deutch connector or the older red plug model?

I have the Johnson 1991 factory service manual for the 120 to 300 horse 90 degree loop V outboards. Bet the wiring is the same. I still have such a motor, so I'm holding onto the manual.

If you can't find the manual you need, let me know which electric diagrams you need and I'll see if I can scan and send.

I suspect the real problem is in the electrical connections at the remote control or in the engine harness connector, not the keyswitch. The manual has an electrical troubleshooting section for the remote.

Please explain what to look for. The problem is he replaced the ignition switch and I'm not sure if its the correct switch. Can the match up a switch using the model number off the motor.

There will be a connector that the switch would normally plug in to..
I believe that year should have a plug like this that would plug in to the engine harness..

There were only a couple ignition switches for those years.. Hopefully he stayed with an OEM model and didn't go aftermarket and hack up the wiring harness..

I owned the boat prior to him for 12 yrs and it never had a plug and the wires connected directly to the post on the switch. I think the link fishie1 provided has the info I needed to get this problem corrected. I'm going to start with a new OMC switch and move foward. He also replaced the starter so that could also be an issue.

The wires coming off of the ignition switch should go to a plug of some sort..

Either way, you should have pleanty of info there to get you going in the correct direction..
