8 Gears

Our electric circuit is out of order and we need someone to fix it. Can you look at it and help us? You will surely find out the solution. It seems that a few gears that provide power to the power supply have stopped working. Reason? Someone did something about it and some wheels were moved to the wrong places. The circuit now does not work and we are without energy. Move the individual gears to the right places and restore the power source. Have fun.
