Power Circuit Probe Tester with Overload Protection and Component Activation, Polarity Identify Continuity Short Circuit Tester 6-24V with LED Test Light, Buzzer Warning,13FT Long Extension Cable

[ Polarity Testing & Continuity Testing ]: The power circuit probe tester can be used to test uncertain contact polarity in vehicles. When the it touches the positive pole, the indicator light will turn on red, and when it touches the negative pole, it will turn on green. In addition to polarity testing, the power short circuit finder can also perform continuity testing, it is mainly to test whether the circuit has continuity and whether it is short-circuited. [ Quickly Tracking and Locating ]: The automotive circuit tester is mainly used to test the on-off condition of the automobile electrical system under the 6-24V DC voltage.In most cases, a short circuit or momentary overload of a component will cause a fuse or circuit breaker to blow. When the fuse is blown due to a short circuit, using this circuit tester can help you quickly and accurately find the faulty wire and its fault point.
