I haven't measured the current, only voltage. To do it, I have to break the circuit somewhere, right? I can't just touch two points.
Edit: I measured in series with the input 12V screw terminal and the power source. It was about 135mA.
How can I locate this drain? I have disconnected everything and it gets hot. No other component is hot, not even warm. Perhaps something under the stepper drivers.
About the diode, I can buy a 20/30V with 1A just to be sure. Three times the price though.
