ADVANCED POLARITY & CONTINUITY TECHNOLOGY Built-in high-precision voltage sensors and a smart microprocessor, instantly detects positive/negative connections and checks continuity to find broken wires or weak grounds. LED indicators show results at a glance (Red = +, Green =, Off = Open Circuit), while the TFT color display provides detailed readingsmaking electrical testing faster, easier, and more reliableCOMPONENT ACTIVATION & SIGNAL TESTING Instantly power and test fans, pumps, relays, lights, and motors on the vehicle before replacing them, saving time and costly parts. Plus, trace AC signals, measure duty cycle, and verify sensor outputs in real time to uncover hidden wiring faults and weak grounds.
No jumpers. No guesswork. Deliver precise results and professional confidence every time40FT REACH, BIGGER JOBS MADE EASY Most probes only cover small cars. Our 40FT cable (20FT + 20FT extension) reaches trucks, RVs, even buses bumper-to-bumper without moving the tool. Dual power options (battery clips or cigarette lighter) keep you working anywhere. Built-in flashlight brightens dark bays and a buzzer confirms signals, so you can find faults faster in tight or low-light spaces. Work bigger, safer, smarterSHORT CIRCUIT LOCATING & OVERLOAD PROTECTION Uses low-voltage pulse tracing and precision sensors to quickly detect and pinpoint short circuits in wires and connectors.
Built-in smart overload protection safeguards both your vehicle and the tool during testing. Diagnose faults faster, prevent damage, and complete electrical repairs safely and efficiently with one reliable, pro-grade tester
