I am trying to get my ignition on my 1968 Sea Swirl wired up to my 1968 Johnson 40 horse model Rd-30d outboard... I have a basic solenoid with 4 posts...I know that the far left post goes to my starter...and the far right goes to my battery positive terminal...but I am confuse as to which wres off of my ignition I plug to the middle posts on the solenoid. And then what do the other wires do??? I have 6 wires coming from my ignition... I will post links to pics of the ignition itself... coming from the ignition and of the solenoid...

Wires coming from the rear of my boat up to my ignition are as follows:
brown,white,black, black with white stripe,red and green for 6 wires total.
brown wire...goes to nowhere under my boats dash...the white wire, black wire, black wire w/white stripe go to the ignition. The red wire goes to the choke button and a green wire goes to both the ignition and choke switch...
I really would appreciate some help on this matter... it is one of the last things I need to do before I can get her out for a test drive...

Thanks!!

Re: Help wiring starter solenoid to ignition

The large green wire is the 12 volt supply and should be connected to the same post as the positive battery cable. The green jumper to the choke just supplies power to the choke switch. The red wire should go directly to the choke solenoid. The white wire goes to the small solenoid post next to the battery cable. When you turn the key to start, that wire closes the solenoid circuit and supplies power to the starter. The two black wires should be the kill circuit. They don't connect to the solenoid. There should also be a ground wire from the other small solenoid post back to the engine block.

Thanks so much!!!!

So then do I ground the black kill switch wires somewhere? or do I even need them wired anywhere? Can I just leave them alone?

Re: Help wiring starter solenoid to ignition

One kill wire goes directly into the magneto (connects to the upper cylinder points. The other wire probably connects to the cut-out switch, which then connects to the lower cylinder points. They don't have to be connected, but without them, you'll need to choke the motor to stop it.

Re: Help wiring starter solenoid to ignition

Okay...thanks again...sounds like its something that I want to have hooked up. I will get to it tonight after work and post on here the results. Can't tell you how mud I appreciate the info.

Re: Help wiring starter solenoid to ignition

Okay upon looking at my magneto, u have a little set of wires coming from it down to a clip there appears to be 2 black wires inside...is this my kill switch? I am assuming if it is I could just cut the clip end off and wire it to my 2 black wires from my ignition harness and be good to go right?

Re: Help wiring starter solenoid to ignition

There should be two black wires coming out under the armature plate. They may end in knife switches. One wire should go to the center of the cut-out switch then jump on to the "M" terminal of the ignition switch via the wiring harness. In other words, you should have two wires attached to the center of the cut-out switch: One going to the magneto and one going to the harness. The other black wire should go directly to the other "M" terminal via the harness. If you connect the wires direct to the harness, you'll by-pass the cut-out switch, which isn't a good idea. You want that hooked up in case of a runaway situation.

Re: Help wiring starter solenoid to ignition

Okay now I am lost...I think I see the two wires coming from the same place my spark plug wires go into just on the other side is two maybe 18 guage black wires in a heat shrink...going a clip end. Do I need an additional parts or is there something actually called a cut out switch that I needto buy separately?

Re: Help wiring starter solenoid to ignition

Here's a pic which shows the cut-out switch and how it's wired. This may not be the exact location on your motor, but they're all pretty much wired the same. It's a little hard to see but there are two wires in the center of the switch - one goes into the harness (to ignition switch) and the second wire goes up into the bottom of the magneto. The white wire is the ground which goes to that small terminal on the starter solenoid. It also jumps up to the safety switch.

Re: Help wiring starter solenoid to ignition

Alright, I see the cut out switch on my motor. Looks almost exactly like the one you pictured. I am kinda following you now. On the black wires coming from the bottom of my magneto one of the wires goes to the center of the cut out switch... and the other goes to a simple clip end but nothing to clip to it is just hanging there. You also say that a wire needs to go from the center of the cut out switch to my harness to the ignition...is that just the black wire for the kill switch?

So would I then be correct to wire the two black wires I have left in my harness coming from my ignition that you say are for my kill switch go to as follows???

1- middle of cut out switch, where the one black wire from the bottom of the magneto goes to...

2nd black wire- black wire coming from magneto with the clip end

Thanks very much for all your help up to this point by the way. I realy do appreciate it beyond measure,


Heres what I got done so far... just so you know where i am at


I got the green wire from my harness wire to my positive terminal, the white wire is connected to the small post on my solenoid closest to the side that goes to my battery, I grounded the other small post on my solenoid to the other side of the white wire coming from the cut out switch like you instructed. So that only leaves the two black wires the black one and the black with a white stripe, the red choke solenoid wire which I do not need because my motor does not have an auto choke and the brown one that doesn't go anywhere.

Re: Help wiring starter solenoid to ignition

Also, in the pic you attached, on the white wire...I only have the part that goes from the side of the cut out switch to up under the magneto where it goes into a clip thing that has a male slot adapter where I attached the ground wire for the little post on my starter solenoid... I see in the picture however that you have a wire going into it, at the bottom where the white wire is attached to the cut out switch, what is that wire coming from? the ignition? hat is it for? am I missing something here?

Just when I think I almost have it figured out something else confuses me.

Make sure that wire connected to the post next to the large battery post goes to the "S" terminal on the ignition switch.

The white wire coming from the small solenoid post next to the large starter post can go directly to the side post on the cut-out switch. There should also be a second wire on that cut-out switch side post going up to the safety switch, as in the picture. That white wire is just running under the bracket which holds the safety switch in place, and then connecting to the switch, which you can't see very good in the pic. It sits right under the flywheel.

Re: Help wiring starter solenoid to ignition

Thanks again...I cannot wait to get home andhook up the last two wires and try to fire it up...I cannot be positive my white wire in my ingition harness that goes to the starter solenoid small post next to the postlitive battery post runs to the S on the ignition as my ignition isn't labeled at all. I am just going off of what your first reply ib this threadvsaid to do...

I will post a response tonight whith whether it all works and what not.

Re: Help wiring starter solenoid to ignition

Upon closer inspection tonight, I see that my ignition has an "S" where my green positive wire and also my white wire that goes to the small solenoid post closest to my positive battery side has an "S" by it as well. The other two posts on my ignition switch where my black wires from the harness, that are wired to my magneto and cut off switch go into have "M" by them. So I thik all is good and hooked up right. I was unable to test it out because one of my tires on the trailer is flat and I could not get the boat out of the garage to hook up the hose and flush thingamabob to the motor... Maybe tomorrow...eh I dunno

But I really appreciate the help getting this ignition all wired up.

Now its on to my lighting...lol but that will be another thread!

Re: Help wiring starter solenoid to ignition

Was finally able to try and start the motor tonight with no success. Brand new battery so I know it has charge.But when I turned the key nothing happened. Absolutely nothing. Not a click or noise of any kind.

Where should I start? I double checked the wiring..everything is tight and right according to what has been posted on this thread. Bad solenoid? Bad starter? Is there a way to test the solenoid? Let me know if you need any pics or additional info.

Help Please!!!! I do not know where to go from here!!!! :mad:

Re: Help wiring starter solenoid to motor

Check continuity of wires with an ohmmeter. May be a break somewhere. Also check ignition switch - make sure when you turn the key to "start" that you have continuity there. You can check the starter by jumping directly to a good battery to see if it spins.
