You will need to add a pull-up resistor to see the output go high.

I migth be stupid, but I can’t really figure this out. The funny thing is that whenever I disconnect the wire that goes from pin 7 to ground, the LED starts to light.
So just to be clear, we agree that if both inputs are 1, the output will be 0. I’m using a breadboard as you can see beolow, and no matter what I do, it wont work. The 74HCT03 has open-drain outputs.
