Power Circuit Probe Tool (P100)

Key Features

• 【 Professional Automotive Circuit Tester for 12V/24V Diagnosis 】 Topdiag P100 is designed for 12V cars, motorcycles, and 24V commercial vehicles. This automotive circuit tester combines DC voltage, polarity, continuity, resistance, AC signal testing, component activation, and power/ground testing in one handheld power circuit probe tester for efficient vehicle electrical diagnosis.
• 【 Four Testing Modes for Efficient Diagnosis 】 Topdiag P100 provides four modes: DC voltage, AC voltage, resistance, and tone. DC mode measures voltage, AC mode supports frequency-related checks, resistance mode verifies circuit continuity, and tone mode provides audible feedback for faster diagnosis in hard-to-see areas.
• 【 Clear TFT Display & Essential Circuit Checks 】 This car electrical tester supports DC voltage, polarity, resistance, continuity, diode testing, AC signal testing, trailer light testing, and ground/short circuit checks. The TFT color LCD and LED indicators provide clear readings and polarity feedback in garages, engine compartments, and hard-to-reach areas.
• 【 AC Signal Testing for Vehicle Circuits 】 With a 0Hz-10kHz tone frequency response, Topdiag P100 helps inspect AC signal circuits, including MAP sensor signals and other electronic circuits during vehicle diagnosis.
• 【 Open Circuit Tester with Built-In Protection 】 The auto circuit tester probe helps locate wiring faults, short circuits, open circuits, and poor grounding issues. Built-in 1-10A circuit breaker protection helps reduce overload risk during component activation and circuit testing.
• 【 20FT Main Cable + 20FT Extension Cable 】 The automotive circuit tester comes with a 20FT main cable and an additional 20FT extension cable, providing up to 40FT of extended reach. Ideal for testing trucks, commercial vehicles, trailers, tail lights, trailer plugs, and other hard-to-reach wiring areas.
• 【 Daily Repair & Wide Vehicle Application 】 Powered directly by the vehicle battery, Topdiag P100 is suitable for garage repair, workshop diagnosis, roadside checks, 12V cars, motorcycles, 24V commercial trucks, trailers, and low-voltage vehicle electrical circuits. Do not use it on high-voltage battery circuits.
• 【 1-Year Warranty +24 Hours Service 】 We provide a solid 1-year warranty service and a 60-day no-reason-asked return and exchange guarantee.Our tech support is available 24/7 to quickly resolve quality issues, usually within 24 hours.With worry-free protection throughout the process, you can enjoy a peace-of-mind experience to the fullest.
