Throttle/Shift safety wiring?

[rost495]

Have a throttle/shift setup, has TNT with it. Have those wires ID'd no problem.

There is a micro looking switch inside the unit, has 2 wires coming out of it. Have no clue where they go to. Boat was bought torn apart.... I'm guessing a kind of neutral switch??

Where do they go and how to hook them up?

THanks, Jeff

If its a neutral safety lock-out, it'll be closed when the shifter is in neutral, open otherwise, and will be wired in series with the "S" (start) terminal on the keyswitch, a yellow/red wire on most boats.

Forgive me, I'm in over my head, just know enough to be dangerous and cheap....

In series meaning I find the yellow/red wire, and interupt it with these 2 wires? Like putting a light switch in place or same as what I'm thinking I have to do for the kill switch but kill switch goes to the black/yellow wire?

Thanks, this has been a real ride, buying a boat with parts and wires in boxes and the boat all taken apart...
But still fun and not workable without all the fine info here.

right, you got it. a digital autoranging multimeter would come in real handy with what you're doing. walmarts has one for about $25.

the kill switch works a bit differently, though. One wire from the switch is tapped into the black/yellow, and the other is connected to a ground wire.

Re-wiring your boat - a real labor of love.

Re: Throttle/Shift safety wiring?

Have an analog meter, so I'm sorta ok. I know more about AC than DC and little about boats...

Got it on the neutral switch and the kill switch. Do not have any batteries yet, have a 12V gel cell from the deer feeder that I get current from to test a bit, but it won't even honk the horn... so I'm wiring away trying to get it all settled best I can and then get 2 good batteries and offer a prayer up...

I have a question about the sending source from the motor for the tach in the Johnson forum FWIW, in case no one else has answered that one....

I'll be able to say I did it myself though and that makes me happy, with instruction from lots of good folks here!!

Thanks, Jeff

Well I thought I'd posted it......
94 Johnson 200 HP, where do I find the lead for the tach sending wire on the motor, IE have the tach in the dash, but no wire to the motor?

should be a gray wire in the wiring harness

If I understand the above quote, get you a fire extinguisher and stand by when you put a battery to this set-up. What you do by tying the neutral switch and the Kill switch together is put + battery voltage to ground and it will smoke. Those are two separate circuits.

Re: Throttle/Shift safety wiring?

Hope its not that bad.... The neutral splits the yellow with red stripe wire, teh kill goes to a black with yellow and the other is black... Not hardly the same wires, but I may not have been clear on that.

Regardless the small battery will test it all out and voltage before I go to a large battery.

Thanks, Jeff

Re: Throttle/Shift safety wiring?

It sounded like you had them wired together and just thought I would put up a warning for you. I just finished doing the same project to another boat I acquired and had to research lots to find the right way.

Re: Throttle/Shift safety wiring?

Thanks for the input, just found out exactly why something on the ingnition harness looked strange with a fusible link, ended up answering a couple of other questions !!!

Its fun, but then pulling all the rigged wiring from someone else, going back a way you understand much better, and then cutting, crimping, soldering, liquid tape and heat shrink all takes time while cramped up under the console.
