allsun 6-24Vdc Automotive Electric Probe Circuit Tester Car System Diagnostic Tool Test Light Power Continuity/Polarity of a Voltage, Cable Length 5m(16ftLightBuzzer

INTRODUCTION This circuit tester is the best car electrical tester for reducing diagnostic time in automotive electrical systems. After a simple hook up of it to the vehicle's battery, an automotive technician can conduct a positive or negative battery current to the tip by rocking the power switch forward or backward. The circuit tester is short circuit protected and can test for bad ground contacts instantly. It allows you to follow and locate short circuits. It can also test for continuity with the assistance of its auxiliary ground lead. FEATURES Overload Protection: The circuit tester is equipped with a built in circuit breaker for overload protection. After the circuit breaker trips, it will be reset automatically. 16ft Cable Length: The cable length is approximately 5m (16ft, allowing you to easily test any electrical system. No Extra Battery Needed: The circuit tester is powered by the 12V vehicle battery directly. APPLICATIONS Quick self test Polarity testing Continuity testing Activating components out of the vehicle’s electrical system Testing trailer lamps and connections Activating electrical components Jumper lead feature Checking for bad ground contacts Following and locating short circuits.
