Johnson Command center Kill switch

[wiscoboater]

Hi guys,
I want to wire a modern kill switch with lanyard into my GT 150. Can anyone provide a description or diagram of how to do this with my command center controller. If I have to mount the switch to the side of the boat or the dash thats fine, I’ll sort that out later. For now I’m just looking for wiring specs.

Thank you,
Jeff

Have you bought the kill switch and lanyard yet? Mine came with instructions that are easy to follow, even for me!

I have not. Was waiting to see where the best mounting location would be before I did. Im putting a new interior in over the winter and do not have everything located yet.

Do you have a picture of your control box? It’s kind of hard to say where it will fit on the control box, will you be using the OMC/BRP switch/lanyard?

It’s this controller,

OK, kinda figured you would have that box….The ideal solution would be to use one of the system check key switches that has the lanyard built into the key switch, but I don’t think that idea will work….The system check key switch has push on lead terminals, and I don’t think there is enough room inside the box to accommodate it. That box is a royal pain to pull apart, and pieces tend to fly when you do….
I guess I would try to use #52 from the standard control box:

and see if it will mount your lower cover: #32: 317912 I guess the question is will the switch be able to sneak in there with the two control cables, I guess you won’t really know until you have the switch in your hand and the cover off the control box. You will need the lanyard, nut, and switch cover as well.

Jeff; I think what you might want to consider is a boat mounted stop/lanyard controlled switch kit like #174654. It can mount wherever you like so it is convienent to hook to your leg/arm, etc. The later System Check switch is a pain in the rear to use. It mechanically turns the motor off, but makes it hard to choke the engine without shutting it off. Like Don said pretty sure not enough room in the old box. Don’t have to worry about putting anything in the old box this way, just run the wires (black & black/yellow stripe) out the bottom of the cover (slot provided) to the kit. Just another option?

Jeff; The other way you can go is the switch designed for that control box! Can’t believe it is still available, but it is. #173298 is a mechanical device that just turns the key off by a lanyard. It’s old school, but they do work. It’s cheap $25 from ME. Took me a while to find it.

Good find Dan, quick and easy….That 173298 kinda works like the system check lanyard set up, correct? Mechanism simply turns the key off, no extra wiring…

It does Don, but a whole lot better! I really don’t care for the System Check setup. The lanyard gets woren just the least bit and it doesn’t stay on well. It is hard to prime the engine without the engine shutting off. I have added many electrical switches to boats instead of the Systen Check setup. On top of that the customers doesn’t understand why he can start his engine back up after he has the lanyard in his hand. They have no distinction between an electrical switch and a mechanical one. Never was explained to them by their selling dealer.
