John Deere 140H3 wire diagram

lampbum2 · Dec 22, 2018

I have a 1969 140 H3, T0586- 010513M. I need a wire diagram, thank you ahead of time.
I am new to this sight here.

Welcome!

By serial number your 140 would have originally had a electronic/CDI ignition system. Parts were always expensive and got worse over time, and harder to find, so many were changed over to a standard "Kettering" ignition system with breaker points and an automotive STYLE coil.

Do you know if this has been done to yours?

I have wiring diagrams of the original system on the tractor, and how the changeover to a points system was done, but the original diagram is at a location where I may not get to 'til Monday, if no one posts a diagram sooner.

If you do not have a Kohler manual for the K321 engine (which includes info on the several ignition systems), you can view or download one at the link below.
