nineteensixtycaddy here's your post 35 hp wiring

[freddyray21]

ok, I don't seem to be able to start my own thread, so I'll sorta hijack this one, as it relates to my motor. I've also got an old 35 evinrude lark, with 5 wires only. two thick ones, one going to what appears to be a makeshift starter solenoid, and another to to the block. Then three small ones, one to the front of the motor up under the pull start, another to the rear of the motor, up under the pull start, and a third to the starter solenoid, I'm assuming that's the starting wire for the solenoid. So.. my question is, other than wiring the positive and negative thick battery cables to a good battery, what do I do with the other two wires going to the motor, before I touch the start wire and try to crank this thing. ??????

Re: nineteensixtycaddy here's your post 35 hp wiring

the two thick wires are the hot wire and the ground. The hot wire goes to starter and the ground to the block. Those grounded through the bolt that attaches the wiring harness plug to the motor. You should have two black wires coming out from under the magneto. One goes directly to the key switch. The other goes to the port side of the engine to the vacuum cut off switch. A wire will then come from that switch up to the key switch. Those two wires make up the kill circuit. Tie them together and no spark. unhook them and it will fire if everything else is good. there will be one more wire coming from the mercury safety switch on the throttle. This goes to the solenoid on the left side if you are looking at it. It provides ground to the solenoid. The mercury switch shuts the ground off if the throttle is too high. If you have an electric choke there will be one wire going to it. The solenoid has two large posts. Looking at it the one on the right is for the battery the one on the left to the starter. The small post on the left give the ground as mentioned. The small post on the right gets 12 v from the key switch to activate the solenoid and engage the starter.

freddyray, thanks so much for your posting this, and your reply to it!!! I don't think I have a wiring box, and I don't have any switches at this point. I will print what you wrote, and carry it out to take a LONG look at what I do have. I have a neighbor with a digital camera, and will take several photos, and post sometime this weekend, for further assistance!! I DO like knowing that it has an over-rpm kill switch, and a kill switch to turn it off. As for the choke, I'm pretty sure it's manual, as I have a lever on the front port side that goes from "slow", to "start", to "fast". I'd assume that's the choke, or perhaps an idle control? I don't exactly know. Anyway, I need to look at this hard, and take some good photos I think. Thanks again for starting this thread, and I'm sure with the help of you and others on this site, I can get this old boat back on the water eventually

Chris

Re: nineteensixtycaddy here's your post 35 hp wiring

ok, something must be different about my motor, and the one you're talking about, because I don't see any wires on the passenger, left, port side of the outboard, with the exception of the spark plug wires coming out from the magneto, and going back to the plugs. All the wires I have other than those two, are on the drivers, right, starboard side. I'm gonna try to upload a scan of a rough sketch I just made in the garage, and hope you and others can help me here.

Re: nineteensixtycaddy here's your post 35 hp wiring

what year is it? I have the wiring diagram for a '57-'59 35hp, if that's it, PM me with your email and I'll send it to you.

Re: nineteensixtycaddy here's your post 35 hp wiring

thanks for offering samo, I PM'd you. Any other ideas from others would be appreciated. I think it's safe to say my ourboard has probably been jerry rigged a lil bit over the years, but perhaps not too much. Anybody who can make sense out of my diagram would truly be helpful. Note that it's NOT to scale, and not even geographically correct, as the starter obviously lines up with the flywheel over the magneto. All help is truly appreciated

thanks
chris

Looks like someone has done some creative electric work. The black wire going to the solenoid to the mount on the starter should go to the mercury switch, but don't worry about it now as I doubt there is still a mercury switch on it. Just leave it. The green wire from the solenoid goes to the starter switch. 12v will make the solenoid click and engage the starter. The loose red wire coming from the solenoid goes to the hot post on the battery and the large black wire goes to ground post on the battery. The two black wires coming from the magneto are the kill wires. Hook them together through a switch and no spark. Unhook them and you have spark. Hope this helps.

Re: nineteensixtycaddy here's your post 35 hp wiring

btw the slow to fast on the port side is not the choke. It is a throttle control. You may have a manual choke. Post a pic and we can tell you.

Re: nineteensixtycaddy here's your post 35 hp wiring

Ok... can't take any photos, don't have digital, and wal-mart get's expensive.

but here's what I can tell you.

Wired up the positive and negative to the battery leads, and wired one black from the magneto into the positive, and one to the negative. Well, THAT was dumb, as I should have read the responses here first. The wires got REAL hot going to the magneto, and smoked a lil bit, and I disconnected them as FAST as I possibly could!!! Then, I came back, read the responses, and tried again.

This time, put the positive and negative to the battery leads, put a switch on the black wires from the magneto, in the OFF position, so that they were not connected. Then pulled the rope start. I pulled and pulled, and pulled, and pulled. Got some smoke, and a couple backfires. I figured that was a pretty good sign that I have spark of some sort.

The throttle is on the port side, and it's hooked with a cable to a dual lever control.

The gear selector is on the starboard side, and hooked with a cable to the other lever on a dual lever control.

Both the throttle and gear select controls and cables work fine.

The fuel line is connected to a wal-mart boat gas tank, with a bulb, and when I squeeze it more than once, fuel comes out the carb on the motor, so I know it's getting plenty of fuel, if not TOO much.

The bow end of the outboard has a manual choke lever, out for choke, in for off.

When looking at the outboard from inside the boat, the choke is on the left.

Then in the middle, there is an adjustment screw for idle speed, left for rich, right for lean.

on the right there is an adjustment screw for high speed, left for rich, right for lean.

Oh.. one more thing. Connected the green from the makeshift starter solenoid/relay thingie. It turned the starter some, but not enough to crank it. After a few tries, it got pretty hot, so I rigged a jumper wire from the starter directly to a switch hooked to the positive on the battery. Flipped the switch, and WOW did she try to crank. Over and over and over she tried to crank.

Got plenty of smoke, but no firing. No backfire even.

so.. took out the plugs, both oil and or fuel soaked. So I'm letting them dry right now, and typing, and hoping to go right back to put em back in and try again.

Wish me luck, and any ideas are VERY welcome.

Thanks
Chris

Re: nineteensixtycaddy here's your post 35 hp wiring

please see above post, but here's the latest. I figured I'd give it an old try from working on cars and bikes. Why not give it a little gas while trying to start, as in holding the throttle at something more than idle. Well.. the results were interesting. It tried HARD to start, heard it sparking and blowing, but just not catching right, and it backfired. Got it to repeat that three times, but still won't fire and hold.

SO... any ideas?

thought it might be getting warm, so I put it in a bucket of water, wow the backfire was real pretty that try, splattered water all over the place. Won't do that again. Note to self.. H20 + electricity = bad.

Re: nineteensixtycaddy here's your post 35 hp wiring

found out why it wouldn't start. Coil was fried. Am waiting on new coils, and new starter solenoid. Then things "should" work fine. I use quotes, cuz I don't wanna get TOO hopeful

thanks again for all the help
