I thank all of you for your input with my problem. One stroke of good news is that my dealer was bought out by another dealer on Jan, 1. This new dealer is only an hour away instead of the two and a half from the original dealer. They are waiting for me to bring it in. I am having a hard time because I am using the tractor almost every day and I don't want to be without it for who knows how long. Especially since this new dealer hasn't been a Kioti dealer until now. Do dealers give loaner tractors? I sure hope so. My wife wants a new one since this has been a off and on problem for almost the whole time I have owned it. Anyone interested can fly out to California and help with the problem. Our weather is great right now!

As long as it is starting OK for now I would simply wait for a time when I would not be using it for several days. You could rig up a simple push button to start it in the meantime. It might be best to wait a bit anyway, so the new dealer has a chance to get up to speed with the tractors and has some inventory on site. Then you could schedule a time convenient for you both and when the dealer is sure he can devote time to it.
It must be frustrating to have had this problem from the start. But it is just difficult to trace and not a serious defect.

Dang, I was just out in CA, around LA. The weather out there certainly beats the 20s with wind in MI.

Hi all! I finally got around to take my DK40HSE in for the no crank over issue. I got a call yesterday from the dealer and they found the problem. It is a diode on the ignition side of the circuit. Makes sense why when the tractor was hot it wouldn't crank over and when it was cold it would start. They said they ordered one. Heck order me two, this has been a nightmare. I have 170 hours on the tractor. I bet 30 are in idle! I hope all that tried to help me on this gets to see the end result.
Thanks Again,
Nick

bump it to the top.

Glad you reported back Nick. I would guess either the diode in series with the start relay coil or the suppression diode in parallel with the start relay coil.

Yes, thanks for letting us know Nick. I was going to answer your notification of the solution but wanted to study the circuit diagram to see if I could come up with an intelligent question. Of course, no such luck. Until now, when K0ua's comment gave a clue as to where to look. That got me to look up a "suppression diode" and the circuit diagram in K0ua's post #16 of this thread makes a bit more sense.
So, I have some questions. Which diode failed? Where is it located? Are both diodes internal to the start relay or are they separate components?
In looking at circuit diagrams, I notice the HST ROPS tractors have the series and parallel diodes whereas the Cab model just has the parallel diode. I wonder why that is so? No wonder I don't understand these diagrams!
Edit: One more question--does your comment about starting when cold mean the problem diode just failed when the temperature increased?
