It is suitable for diagnosis of all DC 6V to 24V automotive electrical systems and can work well on cars, trucks, boats, trailers, and motorcycles. The tester also has an overload protection device, When the current exceeds 7A, the circuit breaker inside the device will automatically trip and give out a buzzer prompt. - 【Polarity Test & Continuity Test】The power circuit probe tester is made of insulating material and high-quality stainless steel tip, which can help you quickly identify the positive and negative polarity of the vehicle cable and plug. When the dc circuit tester touches the positive pole, the LED should be red; when it touches the negative pole, the LED should be GREEN. The power circuit probe tester is also used to check the continuity of switches, relays, diodes, fuses, and circuits. - 【Component Activation and Testing】The automotive power circuit probe tester can activate components inside/outside the vehicle electrical system, perfect for professionals or car enthusiasts. The LED indicator light and buzzer prompt make it easy to test and check whether the component is defective or whether the rated current of the component is higher than the rated current of the car test light. - 【Grounding Test & 4M Test Lead】The electric circuit tester has a ground prompt device, if the LED indicator turns green and the buzzer sounds, it means the ground is good. If not, the LED remains red and does not beep. The automotive circuit tester is equipped with a 4M extended detection line, covering the front to the rear of the vehicle, making it easy to test the entire vehicle circuit system. - 【Tracking and Locating Short Circuit】The power circuit probe tester uses advanced high-sensitivity probes to provide you with fast and accurate detection. Using this automotive test light can save a lot of time to troubleshoot the car wiring circuit, to quickly and accurately find the faulty wire and its fault point. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09CL7ZDZ5 | | Best Sellers Rank | #192,554 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #291 in Circuit Testers | | Brand Name | CMTOOL | | Color | Red | | Compatible Devices | Cars, Trucks, Boats, Trailers, Motorcycles | | Customer Reviews | 4.5 4.5 out of 5 stars (935) | | Included Components | Power circuit probe tester | | Item Weight | 0.33 Kilograms | | Manufacturer | CMTOOL | | Minimum Operating Voltage | 6 Volts (DC) | | Model | AY-29 | | Part Number | AY-29 | | Power Source | Battery Powered | | Style Name | Circuit Testers | | UPC | 758358922504 | ## Product Details - **Brand:** CMTOOL - **Color:** Red - **Item Weight:** 0.33 Kilograms - **Power Source:** Battery Powered - **Style:** Circuit Testers ## Images ![Power Circuit Probe Tester 6V-24V DC Test Light, Automotive Circuit Tester Car Short Finder, Component Activation, Polarity Identify, Overload Protection - Image 1](https://m.media-amazon.com/images/I/61RyWupGTNL.jpg) ## Frequently Bought Together - CMTOOL Power Circuit Probe Tester 6V-24V DC Test Light, Automotive Circuit Tester Car Short Finder, Component Activation, Polarity Identify, Overload Protection - WINAMOO Automotive Test Light with 3-48V LED Digital Voltage Display, Auto Circuit Tester with Voltmeter & Dual Color Polarity Indicate, Electric Test Pen w/Stainless Probe for Car/Truck/SUV Checker - JOREST 300Pcs Car Fuse Assortment Kit, 160 Mini Blade Fuses Automotive + 90 Standard Auto Fuses + 50 Micro + Puller – Replacement for RV Camper Boat Truck (2Amp 3A 5A 7.5A 10A 15A 20A 25A 30A 35A 40A) --- ## 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.com.kw/products/356505867-power-circuit-probe-tester-6v-24v-dc-test-light-automotive](https://www.desertcart.com.kw/products/356505867-power-circuit-probe-tester-6v-24v-dc-test-light-automotive) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-07-07*
