Short Circuit Finder for Continuity Testing - Have you ever faced issues like headlights not turning on, power windows malfunctioning, or the cigarette lighter not workingwith no idea what's causing it? This multifunctional automotive circuit tester helps you accurately diagnose common electrical faults such as short circuits, open circuits, bad grounding, and abnormal voltage. It quickly pinpoints the problem area without the need for repeated disassembly. You can also test whether parts are properly powered, saving time and effort during repairs.
Test Light- Equipped with a backlit high-definition LCD screen, it provides real-time and accurate voltage readings with a margin of error as low as ±0.2Vmaking even small voltage fluctuations easy to detect. The built-in LED light allows for hassle-free testing in dark environments or tight spaces, so you're never limited by poor lighting.
Fuse & Voltage Tester - Even if you have zero experience with car repairs, you can get started quickly: Connect the red clip to the batterys positive terminal and the black clip to the negative. Once powered on, the voltage value will instantly appear. Simply touch the probe to a circuit point to check continuity, voltage status, and polarity. If an overload is detected, the buzzer will sound immediately to alert youhelping protect both your battery and the tester.

Easy-to-use and accurate car circuit tester efficiently checks electrical systems, continuity, circuit breakers, polarity, components, and voltage.

Convenient for testing and repairing in a dark place.
When the positive and negative poles are connected incorrectly, a warning sound will be emitted.
Easily test voltages in the range of 3.5 V to 36 V and display the values on the screen
