PowerScan Automotive Circuit Tester, Power Circuit Probe Tool, 12-24V Electrical Short Open Breaker Circuit Finder, AC/DC Current Resistance, Duty Cycle, & 20FT Extension Cord, for 99% Cars

COMPONENT ACTIVATION & TESTThis Autel automotive power circuit probe tester can activate components on/off-board electrical system/ equipment, is designed for car technician or car enthusiasts. By activating the signal generated by the component, you can accurately judged whether the component is intact, such as blower motor, power window motor, windshield wiper, rear window defroster, lights, radiator fans, fuel injectors, etc. Autel circuit tester automotive tool can activate component in your hand/ in the vehicle/ with ground etc. INSTANT IDENTIFY POLARITYAutel Car Circuit Tester instantly checks component continuity and quick identifies positive, negative and open circuits.

When the positive terminal is connected, red LED lights up with beep sounds. When the negative terminal is connected, green LED light up with a low tone. If an open circuit, neither of LED light will not light. The indicator light is a considerate working guide to facilitate the smooth operation of detection. CONTINUITY TEST, SIGNAL CIRCUIT TESTAutel Electrical System Probe Tester can test the state of sensors, quickly and accurately judge the connectivity of circuit via transmit signal, performing continuity test. Two ways to
test continuity:
1: In resistance mode, if the resistance is 0.0 and the LED lights up, it means continuity.
2: Power up the connection using the power switch, if the circuit brea-ker tr-ips, that means the resistance is low and there is continuity. TRAC. KING & LOCATING SHORT CIRCUITS, OVERLOAD PROTECTIONThis Autel 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.
