Voltage there is twice higher than on left leg of transistor: ~2,50-2,58 in "TST"
Voltage halves on legs of left capacitor twice to 1,25-1,29.

Funny thing is that when I shorten lower legs of left and middle capacitor (equals shortening left capacitor), voltage of 2,58 is coming directly to left leg of transistor and pump begis to work! Unlinking "TST" drops voltage to 0,8 and pump is not working. This means system begins to function properly.

So what will you advice? Does constant shortening of legs of left capacitor makes sense?
