Unique Integrated Safety Design
This tester features an integrated probe protective cover to fully shield the sharp probe tip. It effectively prevents accidental stabbing injuries, and the protective cap is attached to the unit so it will never get lost. Compact and portable, you can carry it anywhere for on-site vehicle electrical checks.
Precise & Clear Voltage Reading Function
This power circuit probe kit comes with an LCD digital voltage display for accurate voltage measurement, delivering readable data both in bright daylight and dark, dim workspaces.Crafted with sharp stainless steel probe tip, it effortlessly pierces wire insulation and reaches tight, hard-to-access gaps inside vehicle wiring harnesses. The insulated rubber sleeve on the probe tip provides reliable anti-shock protection to avoid electric hazards during testing.
Safe & Reliable for Vehicle ECUs
Equipped with an onboard professional circuit chip, this auto circuit tester is far safer and more durable than traditional analog test lights, eliminating risks of burning out vehicle onboard computer boards.The tail wire adopts anti-bending strain relief design to prevent loose connections caused by frequent twisting and pulling.
Wide Compatibility for 6V/12V/24V DC Systems
Engineered for 6V, 12V and 24V DC automotive electrical systems, this professional circuit test pen handles multiple diagnostic tasks: verifying power supply, checking ground connections, locating wire short circuits and broken cables.It quickly diagnoses faults for headlights, taillights, turn signal circuits, electrical sockets, wiring connections, fuses and open wires on all vehicles.
User-Friendly Portable Structure
Built with an extra-long 5.9 ft PU coiled spring cord, it maximizes flexibility, testing range and freedom of movement during inspection.The sharp stainless steel probe with protective rubber tip accesses narrow spaces and punctures cable insulation smoothly. Coiled spring cords are lighter and more space-saving than solid straight wires, taking up minimal room in your toolbox for convenient storage and instant use anytime.
Simple Step-by-Step Operation
- Identify the automotive component to be tested
- Attach the tester’s alligator clip to battery negative terminal or chassis ground
- Touch the probe tip to the circuit’s opposite test pointThe built-in dual-color LED indicates circuit polarity: red light for positive polarity, green light for negative polarity. After connection, the LCD screen will clearly display the exact digital voltage value for straightforward reading.
