I would never recommend this item to anyone! Mine stopped working too, waste of money... **Q: If i use this tool to check a 24v dc circuit how much current will it draw? my goal is something around 1amp at 24 volts.** A: It depends on what system you checking some starter systems drive to 160 A **Q: Ho long does it take for display to indicate voltage?** A: If your connected to a proper ground such as the negative post of the battery it should be immediately **Q: Does the tester have a visible light? I need to test pulsing ignition circuits and a digital meter alone would be too slow to react.** A: It does not have a pulsing light. The digital readout lights up, then shows voltage. Although you could go off of the screen lighting up, but i'm not sure how accurate that would be. ## Frequently Bought Together - Heavy Duty 3-65V Backlit Digital LCD Circuit Tester, Test Light with 140 Inch Extended Spring Wire, Car Truck Low Voltage & Light Tester with Stainless Probe - JOREST 300Pcs Car Fuse Assortment Kit, 160 Mini Blade Fuses Automotive + 90 Standard Auto Fuses + 50 Micro Fuse + 1 Puller – for Car/RV/Truck/Motorcycle(2Amp 3A 5A 7.5A 10A 15A 20A 25A 30A 35A 40A) - Premium LED Bulb Automotive Circuit Tester, 6-24V Test Light with 135 Inch PU Extended Spring Wire, Sharp Hard Steel Probe Vehicle Circuits Low DC Voltage Light 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.hr/products/276994358-jastind-heavy-duty-3-48v-backlit-digital-lcd-circuit-tester](https://www.desertcart.hr/products/276994358-jastind-heavy-duty-3-48v-backlit-digital-lcd-circuit-tester) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-13*
