If anyone has a 140 with electronic ignition and wants to convert it to battery & points ignition, I've collected the necessary parts & numbers. Prices may vary depending on vendor(s) you choose, but the parts number list is complete. I've also included an instruction sheet from John Deere. Happy motoring and enjoy playin' in the dirt! Bob

Just curious, are the electronic ignition parts unavailable, or are they just unreliable? I'm pretty sure my 140 came stock with points, what year did they start using electronics?

The electric ignition was in 69 only. Deere didn’t bring it back until 88. They are very expensive to fix, it’s cheaper to convert to points, so that what JD did when they failed.

Solid state parts are now very hard to find along with expensive.

That explains it, TY.

I just did a quick search for the 3 primary components of the electronic ignition, stator ($250), trigger ($280), and coil ($235), that's $765 !!! For about $100-$150, the 140 can be converted to points. If you had no spark with an electronic system, what would YOU do? Seems like a pretty simple choice to me! Bob

Wow . I see this post is a few years old but this post just blew me away . I have a 1969 140 h3 thats been dead in the water. I finally got the ambition to do something so I converted a 16 hp kohler and got it running again . I had heard of this conversion but couldnt ever find anyone that could lead me to this information . I still have the 14 hp in a closet collecting dust . Is it worth my while to do this conversion for the sake of having a spare engine and is the engine reliable with this conversion and how hard is it to procure all these parts ? Cheers you got me excited that my 140 is a step closer to being as original as its ever gonna get . Mind you it does look pretty close with the 16 hp kohler
