Electric Voltage Tester Digital Circuit Car Truck 6-24v Tester

This professional automotive circuit tester is designed for precise, safe testing of 2.6–32 V DC systems. Whether you’re diagnosing headlights, taillights, turn signals, fuse connections, or any DC wiring, the sharp stainless‑steel probe and 96″ PU spring lead reach tight spots with ease. Its robust ABS body and insulated rubber tip protect against shocks and accidental drops.

Featuring a bright LED display, the tester delivers accurate voltage readings with 0.1 V resolution and ±0.3 V accuracy—visible in any lighting. The low‑current LED circuitry is computer‑safe and burn‑resistant, safeguarding sensitive vehicle electronics. A built‑in polarity indicator uses red and green LEDs to instantly show positive or negative ground connections, and the alligator clamp can attach to either polarity for true bidirectional testing.

Durability meets convenience in this circuit tester. The long, flexible spring cable resists kinks and wear, while the oversized clip allows one‑hand operation. Whether you’re a professional mechanic or a DIY enthusiast, this tester simplifies electrical troubleshooting and delivers reliable results every time.
