Automotive Circuit Tester with TFT Display & Probe

Professional Circuit Testing for 12V & 24V Vehicles

This circuit tester car electrical probe is designed for accurate, on-the-spot diagnosis of automotive electrical systems. Featuring a clear TFT color display (160 x 128 dpi), it allows you to view voltage, current, and resistance readings at a glance, helping you trace faults quickly and confidently. The sharp, precision probe tip ensures reliable contact with terminals and connectors, while the robust construction is suitable for regular workshop or mobile use.

Powered directly from the vehicle's 12 V or 24 V battery, this tester eliminates the need for separate batteries. A 6 m (approx. 20 ft) cable and included 20 ft extension provide generous reach around cars, vans, and light trucks. The built-in flashlight illuminates dark engine bays and under-dash areas, making it easier to work in low-light conditions. Overload protection automatically cuts off power above 5 A to help prevent damage from short circuits or incorrect connections.

Why It's a Smart Choice

• Clear digital readings - TFT color display shows voltage, current, and resistance for fast, accurate diagnostics.
• Extended working reach - 6 m main cable plus 20 ft extension cable let you access front and rear circuits without constant repositioning.
• Built for everyday use - Rugged blow-molded case, battery clips, cigarette lighter adapter, and sharp probe tip keep the tool organized and ready for field or shop work.
