Kraft & Dele KD136 Genset 7HP 3000/2800W: Oil Indicator Light On - Normal or Problem?

Question

Hello, not long ago I purchased the unit as in the title and after starting it, the oil indicator light is on all the time.
My question is whether in this model, after flooding with oil, the light should be on, and if there is no oil, it will go out because nothing is written in the manual.
For the sake of rectification, I will write that it is the kd136 7hp 3000 / 2800W model

Was the unit new or used? From what I know, the light should come on when there is little oil.

domelk · Answer

Brand new and the light is on all the time after firing

Oil level sensor defective (blocked). For a test, disconnect the sensor connection (it should be with a clip) and if the light goes out, look for faults in this circuit.
On aggregates with such a sensor but without an indicator light, low oil level turns the engine ignition off.

Krzysztof Kamienski · Answer

The oil is OK, I suppose? Given the possible damage to the aggregate, he suggests immediate sensor replacement! There is (as in Chinese engines) the possibility of a design error - e.g. no plug in the oil channel or the like.

If the oil level is ok and the indicator light is on, I suggest that you return the generator to the store where it was purchased.

I called the kraftdele service and got the answer that in the kd136 models the oil indicator works the other way around, i.e. it lights up if everything is ok, and in kd138 (on wheels) it is corrected and it lights up when there is no oil. However, something does not suit me. On Monday I will call again and go on a different barrel.
I don't know what to do with it now.

PS. I unplugged the oil sensor with a clip and it still lights and the unit works.

barton21 · Answer

And touch the insert from the oil sensor to the mass and see if the light goes out

domelk · Answer

After touching the ground, the unit turns off.

barton21 · Answer

So the matter is now clear. When there is no oil, the sensor shortens to ground and turns off the unit. When there is oil, the sensor is open.

Hello. How did you solve the problem with the oil indicator light diode burning ??? ????

domelk · Answer

Hello, the problem with the lit diode solved itself. After several starts of the unit, I changed the oil and now when I start it the diode is off.
