wiring 1960 evin.40hp

[girlwith40]

I got the marine solenoid installed. I bought a new key with Batt acc and ign.(marine). My previous wiring was Batt to pos.term - one wire to sol. I had to choke to kill. I want to wire it correctly.My book says a wire from sol (Sm post) to vacum switch. I don't have that wire and there is 2 wires on that screw already, should i make it three? and then a wire to safety switch, which i cannot find.<br />do I have the right key switch?

Ah!! You got the right solenoid. GREAT! Makes all of this easier. Let me go look at mine and I'll try my best to tell you what you are looking for. You shouldn't have to choke to kill unless one of the magneto wires is not hooked up properly. Can't remember if you said in previous posts if your wiring harness is original. Hope so as this will make life a lot easier if we go by wire color. Please note this.

Re: wiring 1960 evin.40hp

About to get dark and I can only tell at the switch end what is what. Red Wire goes to Batt on the switch. White wire goes to S (starter) on the switch. Both black wires go to M (magneto) to kill it. My purple wire goes to A (accessory) as it has a separate choke button. If your new key switch has another pole with a C, then that would be your choke by pushing in on the key ONLY when it is in ON or START position.<br /><br />At the vacuum switch end I couldn't see real good and two of the wires are "sheathed" over the wiring so that I could not see the colors, but one of the black wires goes to the center and the other mag wire goes to the switch straight forward. <br /><br />Any of this make sense? If not holler back after trying.

Re: wiring 1960 evin.40hp

One of the wires on the corner of the vaccum switch goes to the saftey switch, which should be between the mag plate (under the flywheel) and the engine block, on the starboard side up aftish of where the brass shift lockout bar runs.<br />There should ultimately only be two wires going to the corner of the vaccum switch: the one running to the safety switch and the one running to one of the small solenoid terminals. If you've got extras, trace where they go so we can figure out why they're there.<br /><br />Hope that helps!

Re: wiring 1960 evin.40hp

I have a new keyswitch with battacc-ign-st. The guy at the marine store said a wire from Fat post on solenoid to batt on key switch and from st on keyswitch to small solenoid post. I did that and I have power to one side of the solenoid (Incoming from batt)14.9 approx with the key off. No reading from sol. to starter.<br />I do have two wires going to the corner of vacum, but do not go to solonoid. I think one (white) goes to base of tower shaft(?) Baby steps please

Re: wiring 1960 evin.40hp

The wire you ran from the Fat post to the keyswitch, thats coming from the Fat post which is connected to the battery, not the starter right?<br /><br />Ok, follow the wire coming from the other small post on the solenoid. The one that isn't connected to the keyswitch. It ought to run to the corner of the vaccum cutout switch - does it? There should be another wire coming from the same corner. Follow it - it ought to lead to the safety switch.

Re: wiring 1960 evin.40hp

Stay with Paul on this as he has it going on. As I have posted before, I don't get on here often enough. I stay with posts on subjects tho to keep up with knowledge/help.

 

[girlwith40]

Re: wiring 1960 evin.40hp

yes fat post connected to battery.<br />Only one small post on sol. has had a wire on it.<br />Nothing from sol. to vacum. There is two wires on the bottom left corner - one to up under fly wheel the other to inner original plug "harness". <br /><br />The safety switch - is it a small 1" box with a push/pull switch and a wire on each side - one brown one white. I found this up where the wires run where the registation holder is.

Re: wiring 1960 evin.40hp

You must hook up the other small post on the solenoid for it to do something. It was hooked up to the wire that is running to the plug "harness".<br /><br />That sounds like the neutral/throttle safety switch you're describing. The brown wire should run straight to ground (the block) if it is. The white wire should run to the vaccum switch. Around that time they were switching from the mercury switch to the maroon push button; I'm not sure which yours is supposed to have. <br /><br />We seem to be labouring without this:<br /> Click here.

Re: wiring 1960 evin.40hp

Once again, Paul has this going on. I, unfortunately, do not have access to get you the wiring diagram that he has provided. Some of it may be more involved than you need if yours is like mine as we talked about in previous posts. <br /><br />If some of it is still grey, post soon as I am home this weekend and can look at mine to give some clues if needed. Hope you have what you need tho.

Re: wiring 1960 evin.40hp

oh, I am worried.I'm feeling like my boat will never run again, but I'm not giving up!<br />1) my boat has no generator-thats ok<br />2) I have not found a junction box-is that ok?<br />3) If I move the wires on the cut out switch to match diagram --I'm just worried about burning up the coil or something--my spark plug wires are off, will that prevent damage?<br />4) what is the thing on the right side of picture near key shaped like a shotgun shell with a 20ga wire to it?<br />I have alot more questions. Right now I am "worried"girlwith40

Re: wiring 1960 evin.40hp

2) Yes, that's just fine. A lot of times we find these older ones with the solenoid just mounted to the side of the boat or something.<br />3) Spark plug wires on/off will not matter. Just do not directly connect the small black wires (the ones that lead to the ignition) to the red wires. If you accidently ground the solenoid through an ignition coil, it will not harm the ignition coil.<br />4) The grey 20 gauge wire? That's just the ground for the (optional) tachometer. That wire may not be present. What's depicted is the ring terminal on the end of the wire.<br /><br />To make sure the guy gave you the right ignition switch, what terminals does it have on the back? What are they labeled?

 

[girlwith40]

Re: wiring 1960 evin.40hp

3 term labeled BAT ST IGN

 

[Paul Moir]

Re: wiring 1960 evin.40hp

Wrong igntion switch. <br />Bring it back and ask for one for an outboard motor. Smack the parts guy good. Should have terminals labeled "B(att), A(ccessories), S(tart), M(agneto), M(agneto)". May also have a C(hoke) terminal. You do not need a "push to choke" feature, but it won't hurt to have it there.<br />The key (har har!) thing is the two "M" terminals. Without them, you can't make the engine stop. Tell him it's like a modern outboard keyswitch but you don't need choke.

Re: wiring 1960 evin.40hp

the solenoid and the fuse panel for lights ect.IS the junction?<br /><br /><br />the wire with the knife disconnect is connected to my cut out switch corner.Are these just grounding wires or are they providing power to cut out sw?

 

[girlwith40]

Re: wiring 1960 evin.40hp

Oh thats good news!!!!

 

[Paul Moir]

Re: wiring 1960 evin.40hp

Yup, that sure sounds like it. <br /><br />I'm a little confused here. Are you saying one of the black wires that runs up underneath the flywheel to the ignition system is connected to the vaccum switch corner?<br /><br />Perhaps I should explain the vaccum switch a bit. On these engines, there's a problem that can happen if you suddenly snap the throttle closed, or if you rev the engine hard in neutral. The engine can take off on its own, and spin up really fast. To help with this, they put on the vaccum switch.<br />Normally, the vaccum switch is open. But if the manifold vaccum goes up high enough, long enough (say, cutting the throttle while the engine is spinning fast) the switch closes. What this does is kills spark on one of the two cylinders by grounding out one cylinder's points. It does this through the saftey switch so it will work only if the throttle is near low speed.<br />The starter solenoid is also grounded out through the safety switch, so (by chance) the connection is made at the base of the vaccum cutout switch.<br /><br />The keyswitch stops the outboard by connecting the two cylinder's points together. This short-circuits both top & bottom ignition systems, killing spark. So two wires must be run to the key switch to turn the engine off.

going to order from iboat .<br /> which one:<br /> #18-1801 - 6 terminals, does not <br /> name them. Replaces evin.<br /> 386545,386496,379047,378238<br /> or #420351-1 - 3pos magneto style 5 screw

Makes sense- it was right next to the driver. I never knew it was there

 

[girlwith40]

Re: wiring 1960 evin.40hp

that is correct - vacum corner to under fly (meets with other matching wire)
