Tractormeter

Zetor 7745 hour meter not working.
New sender unit has hour meter, grounding and
tachometer. Cords from unit to instrument, which is
new, too. It does not count hours. What can be the reason? I use a multimeter and signals come from the cord, but it does not start the counter.

This is nothing new, even the old Crystal with the cable type rev counter would do the same. Sometimes when a cable broke when the new one was fitted, the hours didn't move.
So I think you might need to try the clock.

Please take a photo from behind the traktormeter and from the sensor.

i think its possible, that you try to use the wrong combo from traktormeter and sensor.

Had the sender colour coded connections the same as the wire colours?
