DK40SE HST - neutral safety switch problem

[k0ua]

I think paying $120 is way better than having to remember all that! :laughing:

Elementary my dear Watson, Elementary!...

It would not be hard to build the bypass network, especially if you retained the plug on the old pot. You could easily cover it in the liquid rubber for waterproofing.

That double post BS is back!

That double post BS is back!

yeah I noticed.. two of mine in 2 minutes

When the double posting happens I click on the second post and delete it. The first post will still be there.

Thanks for the info on that shifter switch, thankfully I don't got one.

Not as simple as splicing wires, the module measures a voltage drop in the Potentiometer. 5 volts on the one outside lead and ground on the other, then the center lead will have a variable voltage on it depending on the arc of the lever. As you move the lever thru the "gears" L-N-M-N-H the changing voltage is read by the cruise module to determine what gear/range to display in the instrument panel and sends along a signal to allow the starter relay to pull up. To bypass this expensive part you would have to build a resistor network of 2 resistors and tap them in the center for the center lead. This would give you the voltage drop you would need to send a signal that the tractor was in neutral. Of course the N lamp would always be lit no matter which range you were in. I would need to look up the voltage that equals one of the N positions, as read by the module, and do the math to calculate the values of the resistors you would need to put together in your "network".. Clear as mud?

Uhmmm...yeah.....{cough}clear as mud:laughing: How 'bout I send my old one to you for forensic analysis then T & E? PM me your addy....I know you need another project in your life like I do:shocked:

I will be glad to look at it for you. and do an analysis.. I would actually enjoy figuring it out. PM on the way.

OK for those that are interested, I received the sensor from MotorSeven and measured it, and found several "dirty" spots along its arc of travel as measured on an analog ohmmeter. I drilled a hole in the sealed unit and pumped it full of WD-40 to use as a cleaner/lube. While it did improve it considerably, the sensor potentiometer still had one area in its arc of rotation that made the meter jump excessively. I don't have any Deoxit Gold to spray in it. It is possible the correct cleaner/lube might bring it back to life, but it is iffy.

As a side note, the dealers mechanic was out yesterday to change out my cruise unit that I mentioned not indicating the correct range when it was cold. He mentioned that it is a known problem with a few units, and it was changed out under warranty. It was not difficult to get to under the floor pan, about where you left foot would normally rest. It was accessible by laying under the tractor. Two screws and two plugs.

Thanks for the info. Hmmmm, I have not read any cruise control issues...... my cruise contr......wait...nope....not gonna jinx myself.

Ahhh what could happen?! :laughing:

What is interesting is the actual cruise function worked OK, but the cold temp, not indicating what range the tractor is in, and allowing a start in a range problem was something I decided they could fix under warranty.

We have run into this on a few models. Kioti service told us there were some cruise modules that were from a "bad batch" and when they were cold it was like the contacts inside would not make proper connection. We had two units (Landini's not Kioti's but same thing different color) that had this issue. One had a faulty cruise switch in the dash which caused grief with the tractor going into a range programming mode. This same unit also had the cruise unit faulty causing the range lights not to show in the dash. A second unit had a faulty cruise unit and range neutral switch and took a bunch of testing to finally diagnose it. Electrical problems can be a pain since they don't always "act up". Between these couple units, impatient customers, and always the possibility of a faulty key switch, it took some time to diagnose and fix them properly. Glad they are fixed now (for the customers and us!).

HI

Wonder if this part would be covered even if warranty is over.. mine is a 2009 with 620hrs on it and it has this problem. If it and from a bad batch I figure this should not be a cost to me.. I do believe recalls happen when tractors can start in gear.. :0) safety and everything..

Any thoughts on who to contact?

Good luck with that. What ever you do don't call Connie.

I'm definitely going to stir the pot.... :0) they are totally liable on anything that happens from cold or heat if it's a bad part.

Even if we know better to start it with the brake on doesn't make it right. Mistakes do happen and might be someone else or a kid jumping in.. they like to press pedales.. haha

Worth the fight for a few $$.. only a couple hundred but still..

 

[murphy1244]

Well then start with your dealers Kioti rep for sure.

We had a storm this week and this morning was cold.. -14 Celsius didn't have it plugged in or anything.. started right up.. first turn.

But.. no lights on the dash were on.. lol once it got warm the lights came on.. :0) Glad I had the 50hp as the gf kinda was sideways down the driveway 3 feet.. little mistake on how close the side bank was.. haha

I was doing some research and found this post. I have a new Kioti hydro .It appears I have the same 'sensor' as the picture and the location is the same When I turn the key on the 'N" (neutral light) comes on and then goes out.I start the tractor and the light never comes on when I have it in neutral. The manual doesnt tell me much so my question is if its in full running position and you shift to neutral does the light come on to tell you its in neutral/Seems like it is supposed to.

Thanks for your time.

OLD THREAD!!

My 2008?? DK40HST has been shutting off at random. It always restarts. My cruise control stopped working a couple years ago and never seem to have time to look into it. This random dying was happening before the cruise control stopped working. It did it this morning. First it had a split second stall but recovered then less than a minute later died. I recall people having issues with the neutral switch which this says it's a pot. This was the first thread I found. That last few times I thought my leg was pushing on the shifter but have jiggled the lever when running to no avail. I've been living with it as it can run quite awhile then one day it dies. It always restarts just fine.
