John Deere 140 wiring diagram

Duane Fuller · May 29, 2009

I am looking for the wiring diagram for a JD 140 TO581 SN 026938M. This had been posted previously and the responder stated he had 3 different diagrams one of which would cover my serial number. Any information would be appreciated.

I have them. The upload was lost when the photohosting site they were on went belly up and the original scan is on a computer that has long since been retired..

If you can bear with me for a day or two (this being the weekend) I'll grab the manual from the shop and get a diagram copy for you.

At serial #26,938, I believe your's would be the last version before the major serial # break @ 30,000.

In the meantime, would this generic version for ALL tractors up to 30,000 from the jdparts site be of any help?

Thanks for the generic diagram but I was hoping for the diagram that would specify the wire colors for the regulator. The wiring got hot and melted. I purchased the replacement but need to know which wire goes to the a and b terminals. The shop manual version of the diagram might have that information. Look forward to those diagrams.
