COMPONENT ACTIVATION & TESTDesigned for technicians and car enthusiasts, this automotive power circuit probe accurately activates and tests on/off-board electrical components. Diagnose and confirm the functionality of vital systems such as blower motors, power windows, wipers, defrosters, lights, radiator fans, and fuel injectors. Whether in-hand, in-vehicle, or grounded, this scan tool ensures precise testing for a wide range of components.
INSTANT IDENTIFY POLARITYEffortlessly identify polarity and check circuit continuity with the Car Circuit Tester. A red LED with a beep indicates a positive connection, while a green LED with a low tone signals a negative connection. Open circuits are instantly recognizable as neither LED lights up. The built-in LED indicator provides clear, real-time feedback, making your diagnostics smooth and efficient.
CONTINUITY TEST, SIGNAL CIRCUIT TESTThe Electrical System Probe Tester allows you to quickly and accurately test sensor circuits and diagnose connectivity issues. It offers two easy ways to check continuity: Resistance
Mode: If the resistance reads 0.0 and the LED lights up, continuity is confirmed.
Power Mode: When powered up, if the circuit breaker trips, it indicates low resistance and confirms continuity. Perfect for diagnosing circuit integrity.
TRAC. KING & LOCATING SHORT CIRCUITS, OVERLOAD PROTECTIONThis Electrical System Tester utilizes highly sensitive probes to provide fast and accurate detection. This power circuit probe tester can troubleshoot the car wiring circuit, accurately find the faulty wires and their fault points, saving a lot of time. It has a built-in short circuit protection. If overloaded, its internal circuit breaker will trip to ensure the safety of users and prolong the service life of the tester.
20FT EXTENSION CABLE, BUILT-IN FLASHLIGHTThe 2025 newest Electrical System Tester features highly sensitive probes for fast and accurate short circuit detection, helping you quickly identify faulty wiring and problem areas. Code Reader & Scan Tool PS100 saves time by pinpointing issues with precision. Built-in overload protection ensures user safetyif the circuit is overloaded, the internal breaker trips to protect both you and the tester, extending the tools lifespan.
