There is no such thing as a Stupid Question!
Don't be embarrassed of your curiosity; everyone has questions that they may feel uncomfortable asking certain people, so this place gives you a nice area not to be judged about asking it. Everyone here is willing to help.
- ex. How do I change oil
- ex. How to tie shoes
- ex. Can you cry underwater?
Reminder that the rules for lemmy.ca still apply!
Thanks for reading all of this, even if you didn't read all of this, and your eye started somewhere else, have a watermelon slice 🍉.

I just stick a 9v battery on two wires on one end and then test for the voltage with a voltmeter on the other end. If I need to sort out multiple wires, I just feed different low voltages over different wires and test at the other end.
It’s always worked for me :). Wire is wire, as long as you don’t try to run higher wattage over it than it can handle.
