- 【Why Need It】The circuit breaker finder is mainly used to test the on-off condition of the automobile electrical system under the 6-24v DC voltage. 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.
- 【Multi Functional】Automotive electric system is test for continuity. Test for polarity of a voltage. Check switches, relays and the on-off of diodes, fuses and circuits . Test for polarity of electric cables and plugs. Track and locate short circuits. Test for bad ground contacts.Do not use on AC voltage.
- 【Easy To Use】The circuit probe can be used to test and activate components in or out of the vehicle electrical system. Press button to “Positive”side with LED lighting RED. Conact the probe tip to positive terminal of tested component to active the component. If LED turns to GREEN with buzzer, stop testing and check the component if defective or not, or rating current of component is higher than that of this tester.
- 【Widely Applicable】The car circuit tester is suitable for the diagnosis of all 6V to 24V automotive electrical systems and can work well on cars, trucks, boats, trailers, motorcycles, and airplanes. The portable and ergonomic design of the automotive circuit probe is convenient for you to use in narrow areas; the 4-meter extension cord is helpful for mobile maintenance work; the clip with strong bite force is not easy to fall off, providing you with a better experience.
- 【High Quality】The circuit probe is equipped with overload power-off protection. If the current or load is too large during the power distribution process or When the current exceeds 7A, it will automatically disconnect to protect the battery and give a buzzer warning. With its short-circuit protection, you can test for bad ground contacts instantly. The insulation material used in this electrical tester has passed the CCC national safety compulsory certification, which is safe and reliable
