Review: Good product - This is a good product.Has a nice long cord.The screen is easy to read.It's a good price, it's functionality works really easy.I like the carrying case that's a good value for the money and the connectivity is really easy
Review: Great product - For the price this probe is pretty damn good, I’ve used to test radiator fans, retract electronic parking brake motors, and a bunch of other stuff. If you aren’t trying to spend a thousand dollars on a Snap On or Matco power probe this is the probe to get.

## Features

- 【Find Electrical Faults Faster】 The KZYEE KM10 Power Circuit Probe Kit combines a power circuit probe tester, automotive circuit tester, automotive electrical tester, wire tracer, short finder, and voltage tester in one versatile tool. Quickly locate short circuits, open circuits, bad grounds, voltage drops, and wiring faults without removing panels or tracing wires for hours. Red and green LEDs with audible alerts instantly identify positive, negative, and open circuits on 6V–30V systems for cars, trucks, motorcycles, trailers, RVs, and boats
- 【Live Waveform Analysis】 The KM10 features a color TFT display that functions as a real-time voltage reader, showing live voltage, frequency, duty cycle, PWM signals, injector pulses, and sensor waveforms. Helps identify intermittent faults, unstable grounds, weak sensor outputs, and signal dropouts during electrical diagnostics. Visual waveform analysis supports faster troubleshooting and more accurate fault identification
- 【Test Before You Replace】Verify components before replacing them. Instantly apply power or ground to test cooling fans, fuel pumps, relays, injectors, solenoids, trailer lights, motors, and other electrical components. Quickly determine whether the fault is in the component or the circuit, helping reduce unnecessary repairs, save money on replacement parts, and shorten diagnostic time
- 【Built-In Protection for Safer Testing】Designed for safe automotive electrical diagnostics. The integrated 10A auto-reset circuit breaker automatically trips during overload or short-circuit conditions and restores operation within seconds. No replacement fuses, manual resets, or workflow interruptions. Helps protect both the tool and the vehicle’s electrical system while testing sensitive circuits with confidence
- 【Reach Anywhere on the Vehicle】A 20FT main cable plus 20FT extension provides up to 40FT of total reach, making it ideal for trucks, trailers, RVs, buses, and marine applications. The built-in LED work light improves visibility in dark engine bays, under dashboards, and hard-to-reach areas. Includes a durable carrying case to keep your diagnostic tool organized, protected, and ready for the next job
- 【Professional Diagnostics Made Simple】 Built for professional technicians, automotive electricians, and serious DIY users, the KZYEE KM10 Power Circuit Probe Kit is ideal for diagnosing trailer wiring, charging systems, lighting circuits, sensor signals, ground faults, electrical accessories, and vehicle wiring problems. Combining circuit testing, signal analysis, wire tracing, component activation, and live waveform analysis, it delivers fast, accurate automotive electrical diagnostics in one powerful tool
