Re: wiring 1960 evinrude

I think you are correct if memory serves. I thought you could bypass the neutral saftey, but not the vacuum cutout .. yes?

Re: wiring 1960 evinrude

nope<br /> The safty switch is not connected to the mags in any way.<br /><br />It simply connects the ground wire from the starter solenoids coil winding to ground.<br /><br />Just so we all on the same understanding, here is a link to the schematic for the engine<br /><br /> http://www.shareaproject.com/fullImages/1634.jpg <br /><br />I think Dave may be right, have you tried jumping the starter directly from the battery yet?<br />If not, get some jumper leads and connect the negative lead to the engine block (one of the bolts or something big, that isn't painted) and the positive lead directly to the terminal on the starter.<br />If this works, then we can dig further. At the moment, we are starting to run in circles.

Re: wiring 1960 evinrude

Not that it matters much, but isn't the black wire on the cutout grounding one set of points? That aside, I agree with lark .. starting to get a bit dizzy.

Re: wiring 1960 evinrude

Well the diagram certainly helps so it looks like the white wire has to connect in two places on the solenoid, once coming from the ign. switch the small terminal next to the FAT terminal from the battery, and the other one from the safety switch to the cutout switch and then to the small solenoid terminal next to the FAT terminal that goes to the starer, right? I notice what appears to be a small fuse box, where would that come into play?

 

[dafox99]

Re: wiring 1960 evinrude

The fuses are for the charging system. Had to replace that same fuse block on my '65 a couple months ago. I think you are correct, The two small terminals on the solenoid need 12v and gnd. It doesn't matter which one gets which, but we need both. I believe the starter switch provides the 12v to the terminal on the right (in the drawing). The terminal on the left goes to the cutout switch, though I can't tell what role it plays as another wire is connected at the same terminal and goes to the safety switch. As long as either of those connect the wire to ground, the solenoid should work. Had they done the drawing a bit more like an electrical schematic, it would have helped.

Re: wiring 1960 evinrude

So .. IMHO, the upshot is, it looks like your solenoid is working, you are getting power to your starter, and it is not spinning. If you follow lark's advice and jumper straight to the starter, just be careful, you'll get a pretty stiff spark and just do if for a very brief moment with the key off. If it still doesn't spin, I think we've decided you have a bad starter. Also, make sure your battery is good .. and charged.

Re: wiring 1960 evinrude

BTW I just remebered, this is important! the safty switch also provides ground for the cut-out switch. <br /><br />The reason for grounding through the safety switch is to prevent the engine from being started with to much throttle, <br /><br />AND to make the cutout switch work. <br /><br />The cutout switch prevents runaway, which can happen with Bigtwin engines, when there is no load on them, and you open and shut the throttle too quickly. The rev's will try to increase and if the the throttle is closed, then the safety switch is providing ground to the cutout, which be actuated by the vacumme created inside the inlet manifold, thus shorting out one of mags, and thereby bringing the revs back down. <br /><br />If the switch is missing, then one of two situations is present.<br /><br />1. the cutout switch is grounded permanently,<br /><br />you won't much more than half throttle before it kills one of the magnetos.<br /><br /><br />2. the cutout switch has no grounding at all,<br /><br />which means nothing is there to prevent a runaway.<br /><br />Either way, you need the safty switch to be fitted.

Re: wiring 1960 evinrude

Ok, I just got that email, do you also have a big ground wire inside the cowling, going to the engine block?<br /><br />

 

[girlwith40]

Re: wiring 1960 evinrude

No I do not have a big ground under the cowling. That's the only one. I have a braided ground and my solenoid is mounted on top of it. When I do the jumper do I use the boats battery or my car with the motor running- and do i disconnect the battery in my boat. Is a safety switch easy to get?

 

[lark2004]

Re: wiring 1960 evinrude

the boat battery is fine, as long as it's fully charged. <br /><br />The braided ground, does it go from under the solenoid to the engine block?<br /><br />A safety switch should be simple to find, if you have a Evinrude dealer near you, they should have one or be able to get one. <br />An outboard wrecker should also be able to supply one.<br />Maybe someone else on Iboats might have a spare one you can have. I have two, but I'm one the other side of the world.

Re: wiring 1960 evinrude

You should have two large (4 gauge) cables running from your battery though the lower motor cowling. The red possitive connects to the FAT terminal on the solenoid, the black one needs to connect to the engine block, a good place is one of the mounting bolts for the starter, without the ground from the battery to the block the electrical circuits will not be complete, If you've got this try taking a 14 gauge peice of wire and make a connection between the white wire at the solenoid and the solenoid terminal with + cable from the battery.

 

[girlwith40]

Re: wiring 1960 evinrude

I can't see where the braided ground ends exactly but it looks like it goes to the motor. I used a meter and had 13V at the starter with the key turned on. <br />Is this right--With the key in off positon, the test light lights up when touched to the fat post on solenoid with the incoming batt cable. Ground is clipped on outter body.<br />I got no reaction from starter with the 14 gauge test

 

[lark2004]

Re: wiring 1960 evinrude

I think you may have a dead starter.

 

[dafox99]

Re: wiring 1960 evinrude

Girl .. if you read 12V or more at the starter as measured between the engine block and the starter and it's not spinning, you have a bad starter. you should see 0V at the starter when the key is off or in the run position. You should see voltage (and hear that "click")when the key is in the start position.<br /><br />Bad starter I think as well. Uh .. that starter only has one terminal . .right? Lark .. it is grounded through it's case to the block .. yes?

 

[girlwith40]

Re: wiring 1960 evinrude

yes I have one cable to my starter<br /><br />The first blurry close up picture I sent with the wires - Have we established what that is? Could that be a safety switch? It has 2 black and a white wire, one black is grounded to motor one black goes to vaccum , white has knife disconnect on the end and is not connected to anything.

Re: wiring 1960 evinrude

If you look at the wiring diagram that Lark provided, Wiring diagram, the only part in that vicinity with two black wires and a white is the cutout switch, the safety switch should be located on the top portion of the motor on the other side just under the flywheel, the part in the picture circled in blue in Larks second post. there should be one white wire that goes from the cutout switch to the safety switch, there should be one more white wire from the same terminal on the cut out switch that runs to the starter solenoid. If I'm reading the diagram correctly and the diagram is correct for your motor.

 

[girlwith40]

Re: wiring 1960 evinrude

so there are three <br />1) vaccumm<br />2) cut out<br />3) safety

 

[MCM]

Re: wiring 1960 evinrude

Well after reveiwing Paul Moir's description in your earlier post that sounds correct, not being personally familiar with your motor all I hve to go by is the diagram.

 

[MCM]

Re: wiring 1960 evinrude

Girl, after rereading Paul's post again it would seem that the vacuum and the cutout are one and the same thing. Which is what I get from the diagram also, just a matter of terminology I suppose.

 

[lark2004]

Re: wiring 1960 evinrude

only two switchs, the cut-out (operated by vacuum) and the safety.
