I have a breadboard mount 1 kOhm variable resistor.
By itself (not plugged into the breadboard) it works fine.
If I plug it into the breadboard, with nothing attached, and nothing in the same column, and nothing powered up, adjusting it does absolutely nothing.
I have 4 more of these, and nothing else similar. It's for the voltage adjustment for an LM317T, which it is not connected to at this point.
Have I been abducted by aliens and don't know it yet?
