Unlike other circuit testers that require you to use a variety of tools to troubleshoot electrical system problem, our circuit testers are perfectly capable of performing multiple types of services such as continuity testing, component activation, fuse test, checking bad ground indicator, detect voltage and current, positive and negative power supply. - 【Portable Quick】When the vehicle's headlights, turn signals, lift windows, sunroofs and other functions fail, our power circuit probe kit can output positive and negative power to check whether circuit components are normal, and can also perform continuity checks and resistance checks. Through these checks and diagnoses whether the path of the car circuit is interrupted, it can be found which parts of the circuit are intact, which parts are bad. - 【Overload Protection】Our automotive circuit tester tools has a built in 10 amp circuit breaker to prevent overloading and cooking a circuit.The output current can be reversed to form a loop power, and when the current exceeds 20A, This power circuit probe will automatically trip to protect the device and extend the service life. - 【Humanized Design】Built-in Flashlight enables you to work in the dark. Even in a dark environment where you can't see clearly, AUTOOL BT250 fuse tester automotive kit can give you a good view. - 【LCD Color Display】Modern and outstanding LCD high-definition color display. The large backlit screen avoids situations of completing the detection in dark areas, helping car technicians, engineers or car DIYers view readings more easily. Moreover, the display screen is clearer, and the displayed data is more direct and clear. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BFR3XYR9 | | Brand | AUTOOL | | Colour | Black | | Customer Reviews | 4.4 4.4 out of 5 stars (29) | | Included Components | Full sets | | Manufacturer | AUTOOL | | Manufacturer Part Number | BT | | Maximum Operating Voltage | 24 Volts | | Measurement Type | Multimeter | | Model Number | BT 250 | | Number of Items | 1 | | Power Source | Battery Powered | | Style Name | Modern | ## Product Details - **Brand:** AUTOOL - **Colour:** Black - **Measurement type:** Multimeter - **Power source:** Battery Powered - **Style:** Modern ## Images ![Automotive Power Circuit Probe Kit, 12V 24V Car Circuit Tester Electrical System Tool, Digital Voltage Tester, Multimeter, Short Finder,Relay Fuse Tester,AC DC Diode Resistance Tester - Image 1](https://m.media-amazon.com/images/I/31zOHxjJXeL.jpg) ![Automotive Power Circuit Probe Kit, 12V 24V Car Circuit Tester Electrical System Tool, Digital Voltage Tester, Multimeter, Short Finder,Relay Fuse Tester,AC DC Diode Resistance Tester - Image 2](https://m.media-amazon.com/images/I/51JCvTy+niL.jpg) ![Automotive Power Circuit Probe Kit, 12V 24V Car Circuit Tester Electrical System Tool, Digital Voltage Tester, Multimeter, Short Finder,Relay Fuse Tester,AC DC Diode Resistance Tester - Image 3](https://m.media-amazon.com/images/I/518oI8KeEwL.jpg) ![Automotive Power Circuit Probe Kit, 12V 24V Car Circuit Tester Electrical System Tool, Digital Voltage Tester, Multimeter, Short Finder,Relay Fuse Tester,AC DC Diode Resistance Tester - Image 4](https://m.media-amazon.com/images/I/51GT9yme4lL.jpg) ![Automotive Power Circuit Probe Kit, 12V 24V Car Circuit Tester Electrical System Tool, Digital Voltage Tester, Multimeter, Short Finder,Relay Fuse Tester,AC DC Diode Resistance Tester - Image 5](https://m.media-amazon.com/images/I/514jUr11N2L.jpg) ## Frequently Bought Together - Circuit Probe Kit, 12V 24V Car Circuit Tester Electrical System Tool, Digital Voltage Tester, Multimeter, Short Finder,Relay Fuse Tester,AC DC Diode Resistance Tester - Circuit Tester Automotive, Power Circuit Probe Tester, Circuit Breaker Finder, Test Light Automotive with 40FT Cable, Car Fuse Tester, AC DC 12V 24V Car Diagnostic Tool, Topdiag P100 - allsun em415Pro Automotive Circuit Tester,Short Open Finder Electrical Wire Breaker Tracker,Broken Wire Detector Tool,Cable Fault Locator with Bendable Receiver Probe, DC 6-42V --- ## 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.tn/products/504871416-automotive-power-circuit-probe-kit-12v-24v-car-circuit-tester](https://www.desertcart.tn/products/504871416-automotive-power-circuit-probe-kit-12v-24v-car-circuit-tester) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-27*
