@amt.tutoring: Can you properly check an aircraft electrical circuit for continuity? 🔧⚡️ A continuity test confirms whether an uninterrupted electrical path exists between two points. Before testing: ✅ De-energize the circuit ✅ Select continuity/ resistance mode ✅ Verify the meter and test leads ✅ Place the probes at opposite ends of the circuit A very low resistance reading indicates continuity. An “OL” or infinite reading indicates an open circuit. It may look simple—but correctly using a multimeter is an essential aircraft maintenance skill and something every future A&P mechanic should be prepared to demonstrate during the FAA General Practical Exam. Save this for your practical preparation and send it to another mechanic who is working toward their A&P. Need help preparing for your FAA Written, Oral, or Practical Exam?

Your meter displays “OL” when you test from one end of the wire to the other—what does that tell you about the circuit? 👇

Always touch your leads together first to make sure there isn’t a break in either of them. If you don’t do this on your O&P you’ll fail and in troubleshooting it could have you chasing a wire that isn’t even the issue.

my brother in christ, make some interchangeable leads. don't just stick a probe in there💀

Don’t you have to isolate for continuity?

What does it mean when shooting dc on correct lead placement but it’s negative 👀
