Oh ok.. That manual I pointed to was for a 400xl.. There was no mention of a quad version..

I think we really need a wiring diagram.. Are you sure the wiring is different ?  A lot of what you describe sounds much the same as that side by side.. Perhaps if you download the manual, and have a look, and see if it seem to be the same switch gear and relays etc we might be able to figure where to start.

Do you know, does that quad have trouble codes, and have you read them ?

How i can read the codes

Tell me in the mean time.. when you say "When i put power on it takes couple seconds and difflock light starts to burn...", do you mean when you turn the key on, when you use the throttle, or when you start pushing it along a bit, using a lot of power ?

And, do you have a manual for the vehicle you have, and is it for downloadable.. Best if we are both looking at the same manual..

Yes. When i turn key to on position, it takes couple seconds and that difflock light starts to burn. 2wd is selected on controls. 

No manual came when i bought it.  I have tried to find manual or wiringdiags but havent found yet

You should follow their testing and diagnostic process.

UTV has different wiring than ATV.

Is this meant to have an auto engage diff lock does it ? If it detects slip it engages ? Do you have a service manual ?

I'd check the diff is working..  getting drive to the ground.. I'd jack one side of the bike at a time, put it in four wheel drive, and try turning the raised wheel.

If the diff and front drive is working then I'd test the diff lock solenoid is getting power to it, and that it has a good earth, and I'd check the wheel rotation measuring devices if it has any.

Thanks mate for answering. Hisun has servomotor controlled on front axle. 2 buttons on handlebar that controls thst servomotor. Fron 2wd to 4wd ja second button is 4wd to Difflock. 

4wd and Difflock works like it should be but it burns difflock light even when i have  2wd selected. I took controlwires away from diff but still light burns so  the problem is not on servomotor 

When i put power on it takes couple seconds and difflock light starts to burn but His is 2wd. I opened the front servomotor unit but no help. Fuses are ok, Relays are ok. Power is on limpmode when the difflight burns.. Whatta hell is problem. Will it help if i brake the light from the dash...
