- 【 All-in-One Automotive Power Circuit Probe – 12 Functions in One Tool 】 Replace multiple testers with one powerhouse. The KZYEE KM50 combines 12 essential functions—DC/AC Voltage, Resistance, Diode, Duty Cycle, Frequency, Fuel Injector, Continuity, Polarity, Ground, Fuse/Relay, Component Activation, and Trailer Wiring. Diagnose 99% of electrical problems fast. One probe, countless uses—save time, space, and money in every repair job.
- 【 7 Smart Scan Modes – Pro-Level Accuracy Made Simple 】 Simplify diagnostics with professional precision. This advanced automotive circuit tester integrates seven smart modes—DC/AC Voltage, Resistance, Diode, Frequency, Duty Cycle, and Injector Testing—offering instant results without setup hassle. Works with 8–30V systems in cars, trucks, RVs, boats, and trailers. Plug, press, and probe—clear answers in seconds.
- 【 Component Activation & Signal Circuit Testing – Stop Guessing, Start Fixing 】 Directly power or ground components to activate fans, pumps, lights, relays, or injectors and confirm part health instantly. No need to remove or swap parts blindly. The KM50 power current probe identifies shorts, opens, weak grounds, or failing circuits with live voltage feedback. Save labor, reduce downtime, and fix it right the first time—real results, not guesswork.
- 【 Live Waveform Display – See Hidden Electrical Behaviors Clearly 】 Go beyond static readings. The automotive circuit analyzer displays live waveform signals for voltage, frequency, and injector pulses in real time—no oscilloscope needed. Instantly reveal drops, spikes, or unstable duty cycles that basic testers miss. Switch between numeric and waveform view with one tap. Diagnose complex faults faster and more accurately.
- 【 Fast Circuit Finder + Auto Protection – Diagnose Safer, Faster, Smarter 】 Trace broken wires, shorts, or weak grounds in seconds on 12V/24V systems, cars, trucks, and trailers. LED indicators clearly show polarity (Red = Positive, Green = Negative, No Light = Open). Built-in 8A auto-reset circuit breaker protects against overloads—no blown fuses or downtime. The ultimate short finder for garages, workshops, and mobile techs.
- 【 Smart Design + Trusted Quality – Built to Last, Backed for Life 】 Equipped with a piercing probe tip, bright flashlight, LED feedback, and audio beeper for instant confirmation of continuity or polarity. Mute mode ensures quiet work when needed. Includes long power cable, protective carrying case, and rugged construction for shop durability. Covered by 1-year warranty, 30-day r**eturns, and lifetime technical support.
