DK45 HST won't start

[k0ua]

Dennis there are a lot of differences in the Bobcat schematic and the Kioti schematic.. I did not know they were that far apart..

Thanks. I have only measured the voltage coming OUT of the potentiometer between the white and black wires. The voltage goes from 1.29V at Low, 1.76 at Neutral1, 2.48 at Medium, 3.16 at Neutral2 and 3.68 at High. I have not been measuring voltages on the preheat cruise module. I don't understand where to find or ground the blue wire, pin 21. If the pre-heat cruise module schematic s different from the Kioti module, then I assume I need to find a Bobcat module which may be a problem.

Bobcat had a better idea?????????????? :cool2:

Before you start changing modules, Identify if you are getting both voltage inputs. You getting one of them, the 12v from the fuse, otherwise you wouldn't have any voltage feed to the Potentiometer. Try swapping the Start Relay with one of the other ones like it. Confirm that relay is functional and it has a good solid ground.

ok couple of things, you called it a bobcat DK45hst.. I assume it is a bobcat right? NOT a DK45hst.. what would that be a CT445? As for the module being the same between the bobcat and the Kioti, I don't know for sure, The schematic that dennis sent along looks quite a bit different, The same but a lot different, including wire colors. What I would do. is find the start relay, It has a coil, 12 volts comes from the Start contacts on the key switch to one side of the coil, and ground is "thrown" by the cruise module, but on the Bobcat it is quite different. See the shematic dennis provided.

Yes it is a Bobcat CT445.

 

[k0ua]

Yes it is a Bobcat CT445.

OK, have you checked the price of the cruise module?

 

[kengreen]

OK, have you checked the price of the cruise module?

Yes, it is $130+ for Kioti module. I will check tonight on the starter relay voltage.

OK, As you know the starter relay is a know weak point on these tractors, but since your gear lights don't work, I lean heavily toward the cruise module being defective.

I checked each of the three relays starting on the right side of the tractor, 70A. All showed 93.8 Ohms between the 85 and 86 pins and all clicked when 12 V was applied between 85 and 86. I am also thinking the cruise module is defective. Is there anything else I can simply test before ordering one? Is there anything the Kioti dealer can check? The module number is T4157 6___ 2 with the middle numbers scratched off
