Don’t rely on colors, use a multimeter and check which is what.

While it may have started out ok someone else could have played in the past... So be safe and check. I only trust wiring I have done...

  • The only time the power should be on is when you're checking voltages. You should have the breaker controlling the circuit you're working on "OFF" all the rest of the time. Good luck.
