Automotive Circuit Tester 8–35V, TFT Display, 6m Cable

Automotive circuit tester kit helps you pinpoint electrical faults fast with a TFT color display, high-sensitivity probe, and built-in work light for clear checks in tight, low-light areas. Designed for 8–35V DC systems, it supports power circuit testing, continuity checks, polarity testing, and wire tracing to locate opens or shorts without stripping insulation. Includes long-reach cabling and a complete probe set for connectors, sensors, and injectors.

• Delivers 5 testing modes for polarity, continuity, resistance, frequency, diode check, and component activation tasks


• Locates opens/shorts with a cable tracer using beep intensity guidance—trace circuits without damaging insulation


• Includes 30 probe accessories for harness connectors, sensors, injectors, and hard-to-reach terminals


• Extends reach with 19.7 ft/6 m main cable plus 19.7 ft/6 m extension cable and universal connectors


• Improves visibility with a built-in flashlight and keeps tools protected in a portable storage case

Stop guessing at wiring problems and move from symptom to source with a circuit tracer and power probe built for real-world vehicle diagnostics. The color screen makes readings quick to interpret, while the multi-angle probes and mini crocodile clips help you connect cleanly without fighting cramped engine bays. Ideal for routine troubleshooting, accessory installs, and intermittent faults across cars, motorcycles, SUVs, boats, and more. Keep the case in your trunk so you’re ready when a fuse keeps popping or a circuit goes dead—grab yours today.
