Never Do This With a Test Lamp!

Free CAN Bus Cheat Sheet Download: https://navvb9.subscribepage.io/ Test lamps have been around forever, but are they helping your diagnostics or misleading you? In this video, we put several popular test lights to the test and demonstrate a common situation that can easily catch technicians out. Just because a test lamp lights up doesn't always mean the circuit is healthy. We'll look at how resistance affects your results, why disconnecting components can change what you're testing, and why understanding voltage drop testing is essential for accurate electrical diagnosis. This video is part of our ongoing Electrical Diagnostics training, where we focus on understanding circuits, measurements, and testing techniques that help you find faults faster and avoid unnecessary parts replacement.
