I wanted to introduce myself, and say thank you for your responses in this forum, I found it so valuable.
I'm a Sugar Cane Grower in Central America and own a JD 4045DF150 engine as part of an irrigation system in Central America. A couple of days ago I had an issue with the engine not starting.
With a mechanic found that some sensor is faulty but he couldn't say what the sensor does to the system. And I was worry that the engine could overheat and get ruined.
Thankfully to your posts in this forum I now understand what the Cold Start Sensor is and found that I don't need it (besides that is not available in my country), as we have ambient temps around 20 ~ 40 °C all year long. (Besides that is not available in my country).
So now i can restart all the irrigation job that is pending and try to catch up with time.
Thanks for letting me find solutions to my issues with the JD unit.
