In this video I’ll show you how I use a Power Probe to diagnose automotive electrical problems FAST — including checking power and ground, finding blown fuses, testing relay command, checking wiring and components, and tracking down a no-crank condition. The goal is simple: stop guessing, stop throwing parts at the problem, and start testing the circuit. We’ll cover: Checking for power Checking for a good ground Finding a blown fuse without pulling every fuse Testing relay command before condemning the relay Separating a bad component from a wiring problem Using the Power Probe safely Diagnosing a no-crank electrical problem step-by-step ⚠️ Power Probe safety: Always know what circuit you’re connected to before applying power or ground with the Power Probe. Supplying power to the wrong circuit can damage modules, wiring, or other electronics.
