2024 DK5320SE HST Cab No Crank

[JErny]

65 hours on a DK5320 SE HST Cab. I have all the dash lights working, but no crank when I turn the key to start. Below is what I have done for diagnosis.
1. Seat switch tests fine and will also shut down tractor when in gear and stand up.
2. Brake switches test good and show parking brake light on dash.
3. Can not find neutral safety switch, but shows neutral light on dash and tractor does or does not shut down when out of seat, so pretty sure it is working.
4. Battery pulled and tested fine.
5. All fuses tested
6. Starter relay replaced and swapped with others. No change
7. Ignition switch tested all wires and all function properly.

I am currently starting it by jumping the hot on the starter solenoid to the signal wire post. It starts right up. I have also tested to know that under crank condition of the key, the white signal wire on the starter solenoid does not show voltage. Signal wire at the ignition switch shows the 12.4 volts when turned to crank.

I found today a bit of rust on the PTO relay. I have a new one on order, but swapped it with a light relay to test and still not getting crank.

My next thing to do is to pull the fuse panel and check for moisture/corrosion/loose wires.

I have worked professionally as a DC electric technician, but that was 15 years ago, so troubleshooting is coming back to me, but still rusty.

Any thoughts or ideas from the group on what to check? Any ideas will be appreciated.

Does the DK have the electronic safety controller? I think it does.

Kioti is Rube Goldberg on the electronics. All your safety switches report back to the safety controller then to the ECU. The ECU allows the start function by completing the ground circuit to the start relay. You’ll have positive voltage going to the relay from the start switch but no start. If you can get some wiring diagrams you’ll be miles ahead figuring yours out.

Just an fyi there are two neutral safety switches on a DK SE Series, one that screws into left hand side of transmission case and another one that screws into top of transmission case. (Near front of seat - under the sheet metal)

One if I remember right is between High and Medium, and other one is between low gear or something like that.

This is a 2024 tractor……why isnt the tractor dealership dealing with this instead of you? Id be so pissed off if my 1 year old tractor wasnt starting…..just saying.

Are you sure you found the proper starter relay? For quite a few years, kioti diagnostic manuals have mislabeled positions for their start relay. On my manual, all 3 relays (start,preheat and stop) are all mislabeled in manual.

You might want to tone out wires to verify you replaced proper relay

That's my thoughts as well. Maybe I've been spoiled by a good dealer who worked with me on my two issues.
