• 1-72V DC Testing with Clear Readout:Neoteck power circuit probe tester operates from a 3-36V DC power supply and measures 1-72V DC test voltage and 0-8A DC current with 0.1V/0.1A resolution. Accuracy reaches ±(1% + 3 digits) for voltage and ±(2% + 2 digits) for current. The LCD also displays supply voltage at startup, helping you check the power source before testing. This automotive electrical tester is for DC systems only-DO NOT use with AC power or test AC voltage
• Find Faults & Power Components: More than a basic circuit tester automotive tool, it checks DC voltage, polarity, continuity, grounds, short circuits, diodes, switches and relays, while allowing positive or negative power to be applied through the probe to test compatible components. Use this automotive relay tester to help determine whether the fault comes from a component or its circuit, making electrical troubleshooting faster and more efficient
• Overload Protection for Safer Testing:When current exceeds 8A, the resettable circuit breaker automatically interrupts the circuit to help reduce potential damage from overloads or short circuits. The power probe circuit tester displays “OL” during overload conditions, with an audible warning in current mode
• Test voltage above 72V DC also triggers an overvoltage warning. Added protection makes this probe tester especially useful when activating components or diagnosing unknown electrical faults
• See & Hear Circuit Status: Get fast, intuitive feedback while troubleshooting. This car electrical tester features an LCD for clear voltage/current readings, while dual LED indicators provide instant polarity feedback—red for positive and green for negative. An audible buzzer provides additional alerts during applicable tests and overload conditions, helping you identify circuit status with this test probe even when working where the display is difficult to see
• 14.7FT Reach for Whole-Vehicle Testing: The 14.7 ft (4.5 m) cable gives Neoteck circuit probe tester extended reach from the battery to rear lights, trailer wiring and other distant test points for easier single-person troubleshooting. The 55 mm probe reaches deep connectors and tight spaces, while the built-in work light helps illuminate dark areas under dashboards and inside engine compartments—making this power circuit probe practical for whole-vehicle electrical checks
• Important Use Notes: This automotive electrical system tester is designed for DC electrical systems only. Before each use, self-check the power probe tester by connecting the red clamp to battery positive (+) and the large black clamp to negative (–). During component testing, disconnect immediately if the LED changes from red to green and the buzzer sounds, as the component may be shorted, damaged or drawing excessive current
• Built for DIYers & Auto Technicians: From dead lights and blown fuses to faulty wiring, poor grounds and component checks,Neoteck auto circuit tester is built for everyday vehicle electrical troubleshooting. Use the power probe around engine bays, fuse boxes, dashboards, rear lights, trailer wiring and workbenches for repairs, accessory installations and component testing. A practical choice for DIY car owners, automotive technicians, repair shops and vehicle electrical projects
