It works with DC voltages from 5V to 120V, making it useful for cars, trucks, boats, and motorcycles.\u003c\/p\u003e\n\u003cp\u003eThe digital display gives you clear voltage readings, so you can test circuits, fuses, switches, and wiring without guesswork. The sharp steel probe pierces wire insulation easily, letting you inspect circuits safely and accurately.\u003c\/p\u003e\n\u003cp\u003eWhether you are diagnosing a blown fuse, checking a trailer light connection, or testing a boat's electrical system, this tool provides reliable results. It is designed for low-voltage DC systems and gives you the information you need to find and fix electrical problems.\u003c\/p\u003e\n\u003cp\u003eUsing the pen is straightforward. Clip the crocodile clip to a grounding point, touch the probe tip to the circuit you want to test, and read the voltage on the display.

He connected the tester's crocodile clip to the negative battery terminal, then touched the probe to the fuse box. The digital display showed 12.4V at the fuse, but when he tested the wiring near the tail light, the reading dropped to zero. He found the broken wire behind the bumper and fixed it in minutes.\u003c\/p\u003e\n\u003cp\u003eMicro Comparison\u003c\/p\u003e\u003cp\u003eUnlike basic test lights that only tell you if power is present, this tester shows the actual voltage on its digital display. This helps you identify weak connections or voltage drops that a simple bulb cannot detect. The sharp steel probe also makes it easier to test through wire insulation without stripping the wire.\u003c\/p\u003e\n\u003cp\u003eSpecifications\u003c\/p\u003e\u003cp\u003eVoltage Range: 5V to 120V DC\u003c\/p\u003e\n\u003cp\u003eDisplay: Digital\u003c\/p\u003e\n\u003cp\u003eProbe Material: Steel\u003c\/p\u003e\n\u003cp\u003eCompatible Systems: 2V, 12V, 24V, 48V, and up to 120V DC\u003c\/p\u003e\n\u003cp\u003ePackage Includes\u003c\/p\u003e\u003cp\u003e- 1 Car Tester Pen\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003e1 Crocodile Clip\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eWhy You Will Love It\u003c\/p\u003e\u003cp\u003eYou get a simple, reliable way to check voltage and circuits without needing a multimeter.
