Was tightening my pull cord on my Lawn Boy 8671 today when something broke. It’s the end of one of wires going to the kill switch. Broke off. The other end is in the mower. Anyone have a suggestion where to get a part or whether a solder will work?

I don't think you can solder it back for a fix.
That appears to be the magneto that it broke off of. Need a new one.

That just a crimp on male side of a blade connector,,,Radio Shack should sell those in a blister pack.

Sorry,,,took a better look at it after more coffee,,,you could make a new one out of thin stainless from say an old hose clamp.

The spade terminal is not the problem.
The problem is soldering it bakc onto the magneto coil without roasting the trigger chip .
It came from out of the middle of the potting resin on top of the coil.

FWIW I would call that not repairable.

Two questions: any idea where I could find that part and second, didn’t Radio Shack go belly-up?

Ok, I think Radio Shack did go belly up.

If you remove the bolt that's in the photo, does what left of the blade connector come off? If it does than just fabricate a new blade connector. shouldn't be hard to do with a pair of tin snips and some thin stainless or regular steel.

Bert, this isn't the wire for the coil to plug, just a ground for the kill switch, I think.

Jeff

Can you send us pic,of that kill switch?

have a close look or better still chase up an image of the part.
The male blade did not break off the mounting bolt, it broke off the coil in the middle of the potting resin .
What is missing from the photo is the wire that would have fitted onto it.
And as it is a magneto then good chance you are correct and it is a kill wire.

It looks to me like the spade end of the kill wire broke off. Another one could be crimped back on if you had some of the male ends at home.
The part number for that wire is 681788. You can get one on Ebay for 4.75 and free shipping. Also www.oldmowerparts.com have them for 4.59, but there will probably be shipping. I was looking at the kill switch and it has a black and a white lead, both with female ends. So it still looks like to me from your photo
that you will just have to buy that lead wire or buy a pack of male ends and crimp a new one on. By the way the kill switch is part 682513 if you want to check if that is the same switch on your mower. Let us know if you have any more questions.

Jerry, both you & Jeff are missing the point that the terminal that broke off is no crimped onto a loose wire.
It is soldered to the end of the trigger module which is under that resin.
Thus there is nothing to crimp anything on to.

Depending upon exactly where things are under the resin he might be able to use a bolt on spade terminal secured with a short self tapper through the remains of the terminal in the potting mix like you can do with some PTO clutches.
However you do run a big risk of putting the self tapper through the trigger chip unless you know exactly where the chip is.

OK, I see it now. It broke off of that burgundy colored part of the coil. I can kind a see the little slot where it broke off from. I never would have noticed that from the picture. You know your stuff Bert. I never thought about where the other wire on the kill switch went to. So another CD pack or coil will be needed.
They are still easy to find. Generic ones are not too expensive. Some NOS OMCs are 80 bucks.

Bert is right,and bottom line is you need new coil.

I hate creating dissent on the lawnmower page. Can’t we all just get along? Seriously, I’ll try to get a pic today. It is a female end that is one of two wires off the kill switch. The flimsy, cheap piece of metal that may have been engineered off a Coke can tab broke off inside of the crimped female end. I was able to pull the piece out of that crimp so I’m not sure if the wire is the issue. This female end needs a male and there is nothing but the stump you see. I saw something on somebody’s cheap Lawnboy site ironically at a pricey $60.

Got updated on the coil posts after I’d posted— thanks for the help guys! I’ll start the search.

Dissent is fine it stimulates the brain and makes people go back and check things, provided it does not get personnel & abusive.
Although I have never worked on that model mower I have replaced enough coils to have seen the same thing happen before.
The actual problem is a support for the wire has fallen off which allowed the tab to vibrate back and forth, one time too many.
And credit where credit is due, the very first person to reply had it correct, the magneto is broken.
All I did was correct latter posters and hopefully get them to have a closer look thus learn.
You might be able to dig out enough of the potting mix ( the pinky brown stuff ) to get enough of the contact to solder a wire with a male terminal on the other end to the remains of the original contact.
Then you will need to replace what you dug out and hope the heat did not fry the chip and the goop you fill the hole with makes a seal preventing water getting in.
Some times it is the only way to make a repair because the part is no longer available.
Good luck and let us know what you do & how it goes.

Very well said Bert. Due to the stresses of life I read on forums of misunderstandings both ways. We need to just try to look at the problem and let it go. I have tried the fix with no long term fix, eventually vibrates apart. And you are a very good asset to this forum. Thanks Bert.
