Have a lawn tractor that runs great, no fuel or engine trouble. Problem is that I have a wiring harness issue. Tractor runs and then all of a sudden stops. Brought it to John Deere to fix issue but they couldn’t figure it out. While using it to cut grass, it stopped so I picked up hood and shook a wire and found where the issue was. Is it possible to change just one electrical connection? Does the connector allow it to be color coddd for easy change?

What’s the issues exactly?

It’s a loose molded plug? Just a loose pin? Is a ground connection corroded?

You can easily just jump over a molded plug if you don’t want to replace it and want a quick fix. If you can find the plug, you can replace it. You can also try to replace just a pin.

If it was me, for a lawnmower, I’d just jump over it with a male/female spade connector.

Most of the time I’ve seen, the issue is a corroded ground connection. I’ve just reran the wire to a new/clean ground point.

Hi
I worked on many JD tractors big and small over the years.
One of the biggest issues is what’s called a “floating ground”
Somewhere on your equipment it’s making an intermittent contact to the frame where you should have a good negative ground from the battery negative terminal.
Many times paint from the factory that is sprayed on he frame first will cause this problem.
I would trace the negative terminal from the battery and where it connects to the frame or metal, remove it, sand down to bare metal, reconnect the negative cable coming from the battery, should be good to go.
