• 🏆【 One Probe Tester Replaces All – Diagnose Every Circuit, Fix It Fast 】Highly recommended by YouTuber mechanics like Tomeighty and AutoFun. The KM10 power circuit probe tool combines all key electrical tests -- 🔧 Circuit Breaker & Open Circuit Detection, ⚙️ AC/DC Voltage & Polarity Test, ⚙️ Resistance, Diode & Continuity Check, ⚙️ Ground & Signal Circuit Test, 🔧 Component Activation and 🔍 Wire Tracing. Quickly locate shorts, opens, or bad grounds without pulling panels. Work smarter, fix faster – you deserve this tool.
• 【 Find Electrical Faults Fast – Stop Wasting Time Chasing Wires 】The KM10 power circuit tester kit identifies shorts, opens, and bad grounds in seconds using LED and tone cues. No need to remove panels or fuses—just follow the signal. Ideal for cars, trucks, motorcycles, trailers, and boats, this power tester simplifies fault tracing across 6–30V systems. Built-in overload protection prevents fuse damage during tests, ensuring safe and efficient diagnostics every time.
• 【 See What Others Miss – Reveal Hidden Signals in Real Time 】Acting as a current probe and electrical system probe tester, the circuit tester reads live DC/AC voltage, frequency, and signal waveforms to detect unstable grounds, weak sensors, or intermittent faults. The color TFT display visualizes signals under real load so you can spot issues early. Ideal for diagnosing injectors, PWM signals, and sensor outputs that ordinary testers miss—saving hours of diagnostic time and preventing costly repairs.
• 【 Verify Before You Replace – Power and Test Components Instantly 】Avoid replacing good parts. The power circuit probe kit instantly powers or grounds components such as lights, fans, pumps, relays, injectors, and trailer lights to verify function. One touch reveals if a component is bad or miswired. Activate parts directly through the probe and confirm before replacing. It cuts repair time, reduces part waste, and ensures every fix is accurate the first time.
• 【 Safe, Smart & Self-Protected – Auto-Reset Breaker Built In 】Work confidently with built-in protection. The KM10 automotive electrical tester features a 10A auto-reset circuit breaker that trips instantly on overload and restores power within seconds. Prevent sparks or blown fuses while testing sensitive circuits. The durable design makes this power tester probe reliable for long-term shop use, combining safety and stability in every test.
• 【 Go Further, See Clearer – 40FT Reach & LED Work Light 】 Reach any corner easily with 40ft cable—ideal for long trucks, trailers, or RVs. The circuit tester automotive tool includes a bright LED flashlight and color TFT screen for clear visibility even in dark spaces. Test voltage, signal, and component activation anywhere without moving the battery source. Whether day or night, this probe tester keeps you efficient and in control on every job.
• 【 Instant Polarity & Continuity Check – Know It at a Glance 】Red and green LEDs instantly show positive, negative, or open circuits, while a buzzer confirms continuity. The electrical system tester translates readings into clear visual feedback—just touch, see, and hear. Simplify diagnostics, eliminate guesswork, and get instant confidence in every result. Because every second saved is a win in your garage.
• 🏆【 Trusted by Pros & YouTubers – Professional Results, Real Value 】Recommended by top YouTuber mechanics like Tomeighty and AutoFun, the KM10 Circuit Probe Tester delivers diagnostic capability equal to P~P~3/P~P~4-type tools, but with safer breaker protection, smarter signal display, and greater value. Built for both professionals and DIYers, this automotive circuit tester includes a 1-year warranty and lifetime technical support—because real tools earn trust through performance, not promises.
