Bad news big repair

[shooterdon]

I've seen Hay Dude owns more than one Kubota product. But don't know if he is original owner of all that equipment or not.

He has four tractors. Doubt he needs them all running in the winter. No big urgency I suspect.

It would be crazy to spend $6000 so this one can start in the winter. If he cannot (will not?) run a block heater, he can park it until March/April.

I would put in the auxiliary GP wiring circuit others have suggested but it isn't my problem or machine. My tractor has to run in the winter, or I am snowed in. Hope my crappy LS doesn't catch the Kubota bug. But nice to know there are cheap solutions.

Maybe. Just sales date (especially in tractor business) could be way later, than production date.

5 years would be a very long time for a Kubota to sit on a lot somewhere. I won't say that scenario is impossible but it is HIGHLY improbable.
That's a lot of coin for a dealer to be paying interest on for 4 years.

I agree with you. Just looks like he wants to solve an issue within winter time to have his machinery well working starting from next spring. Preferably according to specification and at lowest cost. And I also understand him.

I would offer some tips, but the OP has me on ignore.

So...

 

[Hilbilly]

The OP has stated that he does not have a block heater and leaves the tractor in a field , where there is no electricity available. Don't know how far this field is from his nearest electrical outlet and don't know his circumstances. However I'm sure he would install a block heater and run the tractor to his nearest electrical source, if it made sense for his operations, rather than spend $6000 for a part that might not fix the issue. He could also run a generator out to his tractor but that might involve traveling back and forth long distances to get the generator running, for a few hours while he returns home and then back again to start the tractor. We don't know his circumstances. Lots of potential solutions have been offered.

In the meantime I wait to see what he comes back with. I note he hasn't replied for a while.

Could you leave all the wiring intact and in-place and splice a hot lead from a relay/switch combo to power the glow plugs? This would rely heavily on the relays to isolate the computer, so a through study of the wiring diagram is needed.

Throwing my $0.02 in the hat.

Leave everything intact. Disconnect GP load from relay. Wire this to another solenoid or relay with a momentary push button.

OR

Disconnect signal ground wire from GP relay. Use a momentary PB to ground relay coil. (Easiest IMHO)

Both will work.

Solution 1 has been offered about 25 times. Solution 2 has been offered several times as well.
For whatever reasons the OP hasn't received either well.

I'm still stuck on a $6000 ECU... that's just predatory. Can they test your ECU to see if it's the problem?

 

[Hay Dude]

Big companies really have special funds for so called "good client", who bought more than one product, was/is loyal in after sales programs, recommended the brand name to the other clients...

Sometimes it works if the machine gets expensive failure even after more than 3 years.

I have bought multiple new tractors from them, but I am well past 3 years. It’s a 2010.

 

[Henro]

I made an honest effort to read all the posts but ran out of steam at maybe page 12 or 15 or so.

ANY way, why not just power the glow plugs separately as others have suggested.

You could install a diode in the original wiring that would likely not affect the function of the original control, but WOULD prevent a back feed into the original circuit. Proper sized diode of course.

This might have already been suggested...thread too long and I ran out of energy reading the reply's.

MY bad I know...

Can you show me where I didn’t receive the repair suggestions well?
Obviously, it’s an option. One that crossed my mind a year ago.

Maybe your attention span doesn’t allow you to understand my preferential repair is to get the factory system working FIRST.

Do you have a problem with that? Do you have a problem with me asking the more patient, more helpful people in this thread provide possible solutions on how to repair what’s there to original factory condition BEFORE I “wire a switch”?

Deal with it…..

Do you have a problem with that?

Unsubstantiated and undocumented fears of an engine derate.
Fear of an electrical fire cause by installation of an alternative glow plug control circuit.
Thats 2 and all the time I'm going to waste on you right now. My BS tolerance is low today.
BTW, if you can't run a couple wires and a switch without burning your tractor to the ground you might want to have someone else handle the troubleshooting and repair.

I don’t think so, but it depends on the knowledge of other people.
Id like to know, because the tractor will retain more of its value in original condition

Please, don’t waste any more of your precious time in this thread. I would appreciate that!
Its like if I don’t fix it YOUR WAY you cry and project on me that I don’t accept your solution

Sucks when you get a straight answer to a direct question I guess.

 

[Hay Dude]

Hook up a 110v oil heater goes down the oil dipstick might work.

I typically keep the tractor in a field, electrical access is pretty limited.

Its quite easy to “wire up a switch”. I’d like to eliminate any/all other reasons that the factory system doesnt work.
I know it’s hard for you to grasp, but it’s ok, I’m patient and will try to remind you repeatedly that wiring up a switch is my last resort, repairing the existing system is the goal.

 

[Snobdds]

Buy the $6k ecu, or bypass...

Well you certainly explained how you've seen " hundreds of tractors" burnt by added wiring. I just naturally figured that was firsthand knowledge if you know what I mean. I'd think after 19 pages you'd figure out the answers you want aren't here.
Sad that you think the workaround is "my repair". About 20 guys have suggested it.
