JD 4320 - err code 4

[stoney1]

Follow Up:

New alternator & fan belt,
batt indicator out, no codes displayed, so far

I’ve left off load and motion match for now.
Load match was on when everything went haywire.

I remember the load match was cycling on in
heavy grass mowing. Then I noticed the flashing
gear indicator. And I noticed the temp gauge was
hot, but I don’t recall seeing a red overheat indicator.

The coolant tank was empty, with hot engine.

After the new alternator, belt, and coolant filled to
the cold line, it seemed corrected for a 2 hr run.

Thanks to all.

Just for information, I also have a JD 4320/ 2006 vintage. I was cleaning my engine air cleaner and discovered a mouse nest directly under the air cleaner. After cleaning I noticed several wires had been taste sampled. Nothing completely severed. I applied electrical tape and added some loom over that area. Part of that harness goes to the alternator, engine start solenoid and engine coolant temp sensor. I have always used "Fresh Cab" in the operator cab for rodent protection. This attack was outside the cab. Just a heads up.

Get some mouse poison out. And mix a bleach/water solution and sprinkle/pour around the area where the mouse nest was located. Mice pee on that area and it attracts other mice to that location. I've had good results cleaning and bleaching the area, and they do not come back. But just removing the nest, they will be back shortly.
