It tests voltage polarity, continuity, relays, diodes, fuses, and more within 6V to 24V DC systems. Featuring sharp probes and LED indicators for quick polarity detection, it safeguards vehicle computer boards from damage and offers a bright backlit display for use in any lighting condition. ## Description FunctionContinuity tester for testing components inside and outside the vehicle electrical system: This electrical tester can be used to test and activate components inside and outside the vehicle electrical system, testing voltage polarity, relays and diodes, fuses and circuit continuity, checking lights, checking motors, Track and locate short circuits, test for poor grounding, test cable and plug polarity, measure 6V to 24V DC voltage, etc.FeaturesCompared with traditional power circuit probe kits, this LED power circuit probe kit has safer operation, protects the vehicle computer board from potential damage and burning, and adopts sharp probes to easily pierce the wires and enter narrow areas.ApplicationLED light prompt helps you quickly identify positive and negative polarity of electric cables and plugs. When the probe tip contact to the positive electrode, the RED light on. When the probe tip contact to the negative electrode, the GREEN light on.Friendly to UseThis circuit tester light is equipped with a bright LED backlit display, ensuring visible test voltage readings in low-light or glare environments.RemindDo not use this item near explosive gas, vapor or dust. When pressing the power switch (Note: or shaking), the battery current will be directly conducted to the pen tip, which may cause Sparks can be caused when touching the ground or certain circuits. Do not use the device under 110/220V indoor current, only for DC6~24V system. There are detailed instructions in the product box, please refer to the operation.

LED showed voltage but nothing from the probe power output. (Yes I did take off the plastic cover!) Sent it back to Amazon, which is the first time I've done that for years. In the end I bought the cheaper version without the LED screen. Was able to fix an issue on a classic car by using it. Not really a negative review but had to give it one star as it was faulty on arrival. ## Frequently Bought Together - ZKTOOL Power Circuit Probe, Automotive Electrical System Tester DC 6-24V, Car Circuit Tester, Short Circuit Tester, Voltage Tester, Polarity Identify, Test Light, Component Activation - JOREST 300Pcs Car Fuses Assorted Kit, 160 Mini Blade Fuses Automotive + 90 Standard Mixed Fuses + 50 Micro Fuse Set + Fuse Puller – for RV Truck Motorcycle(2Amp 3A 5A 7.5A 10A 15A 20A 25A 30A 35A 40A) - JIMCOM Circuit Tester, 6V/12V/24V Test Light Automotive Truck Car Electrical Circuit Continuity Tester Test Light Indicator with Pen Tool Electrical System Tester --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/442564249-zktool-led-power-circuit-probe-automotive-electrical-system-tester](https://www.desertcart.jp/products/442564249-zktool-led-power-circuit-probe-automotive-electrical-system-tester) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-18*
