Professional automotive circuit tester for 6 V–24 V systems Key benefits Accurate diagnostics: Professional-grade accuracy quickly pinpoints electrical faults in 6 V to 24 V vehicle systems so you find the problem, not just the symptom. Protects vehicle electronics and users: Sensitive short-circuit fuses and built-in safety protections prevent damage to vehicle electronic management systems and reduce risk to the operator, allowing confident testing on modern car computers. Faster troubleshooting: Intelligent detection of bad grounds and short circuits shortens diagnostic time — typically up to 50% faster than conventional methods in busy workshops. Durable and easy to use: Lightweight ABS housing offers long-term durability; the ergonomics and flexible cable make repeated use comfortable and practical. Key features Function: Tests and diagnoses electrical circuits, identifies bad grounds and short circuits, and verifies power to components in 6 V–24 V vehicle systems. Compatibility: Designed for a wide range of passenger cars, light trucks, and motorcycles using 6 V to 24 V electrical systems. Cable length and flexibility: Extra-long premium cable, 14.8 ft (4.5 m), provides access to hard-to-reach areas such as rear lights, trunk wiring, and underbody harnesses without awkward positioning. Construction and safety: Robust ABS housing for durability; sensitive short-circuit fuses and internal safety mechanisms protect both the user and vehicle electronics. Performance: Professional accuracy for reliable identification of circuit problems, reducing repeat tests and unnecessary part replacements. Practical applications (use scenarios) Workshop diagnostics: Quickly locate a short or poor ground in a customer’s vehicle tail-light circuit without disassembling trim panels; save bay time and increase throughput. Mobile technician or roadside service: Use the 4.5 m cable to reach components in vans or SUVs from a single access point, allowing safe, efficient testing outside the shop. ECU and modern system checks: Safely verify power and ground at modules and controllers while avoiding damage to sensitive electronic management systems during testing. What you get A professional-quality automotive circuit tester optimized for 6 V–24 V systems Durable ABS construction, sensitive short-circuit protection, and a 14.8 ft (4.5 m) flexible premium cable for extended reach and practical testing in various vehicle sizes and configurations Designed for technicians, mechanics, and advanced DIYers who need safe, accurate, and efficient electrical diagnostics without adding complexity.
