How do I check fuel solonoid ?

spivey44 · Aug 4, 2022

Still trying to get my Dk 40 to start.
I have bleed the fuel system so my next step is to check solonoid.

I took it off and disconnected the harness.
I thought there would be a red and black however there is also a blue wire.

No idea of what this is for.

Anyway I ran 12volts to red and black connections on solonoid and the black "plunger" does not move.
In addition no sounds from solonoid when energized.

Did I test correctly?
Does the blue contact need to be energized as well?

Obviously I am not a mechanic and would appreciate some guidance.

I just do not want to drop $120 on a solonoid which is not in need of replacement.
In addition dealer will NOT accept returns on electrical parts which Iunderstand.

FEIW When I removed the solonoid the plunger is in the extended position and can be pushed in freely by hand and when released it extends back out.

Thanks so much for all your help. I'm sure it was appreciated.

The world needs more people like you.

BTW: No spelling errors.

Have a blessed day !

Here is a page out of Kioti workshop manual for a different model, but should be same as yours.

Some tractor fuel shut off solenoids are energized to turn the fuel OFF. They require a timer controller.

Some shut off systems have TWO solenoid windings. A "pull in" winding to move the fuel tap to open, then another winding to maintain position.

I can't say what your tractor has, but that would be the first information I would be looking for. Diagnostics without knowing what you are expecting can be counter productive.

My two compression ignition engine tractors have pull rods to close the fuel valve. The key switch is for the starter and lights ;-)
