## Description

Application: 1.Continuity testing 2.Voltage polarity test 3. Check switch, relay, diode, fuse, circuit on/off 4.Test polarity of electrical cable and plug 5. Track and position the short circuit 6. Test bad ground contact NOTHING YOU CAN: 1. Do not use around explosive gas, steam and dust. Press the power switch (or lock) and the battery current will be directed directly to the tip and may cause spark when contacting with ground or constant circuit. 2. This unit cannot be used with 110/220V household current. For DC 6-24V systems only. 3. Do not use it on AC voltage. 4.After you finish checking the car, all the connections that disconnected are properly restored. 5. Always follow the instructions and procedures provided in vehicle service manuals before removing any electrical circuit or sub-system. 6. For safety, please do not touch the dangerous part of the car. Do not touch live conductors with hands or skin. 7. Do not use if it is damaged. 8. Some parts of the vehicle operate at low voltage and cannot withstand the voltage set by the product. Do not use to apply voltage directly or indirectly to avoid damage to these parts. 9. Make sure your vehicle is safe and reliable before driving. 10. Do not use this item while driving. Specifications: Working Voltage: 6-24V DC Cable length: about 4m Overload Protection: 8A (current is over 8A, the current will be disconnected automatically) Weight: about 200g Package Includes: 1 x Circuit Tester 1 x User Manual (English)

## Features

- 【Reasons to Use】Circuit breaker finder is mainly used to test the on-off state of automotive electrical systems at 6-24V DC voltage. If the fuse runs out due to a short circuit, this circuit tester will help you find the defective wire and its fault point quickly and accurately
- Multi-functional: Electrical automobile systems are continuously tested. Test voltage polarity Check switch, relay, diode, fuse, circuit on/off Test the polarity of electrical cables and plugs. Track and identify short circuits. Test ground failure. Do not use for AC voltage
- 【Easy to Use】Circuit probe can be used to test and activate components inside and outside of the vehicle's electrical system. Press the button and LED light red on the "Plus" side. Probe tip touches the positive terminal of the tested component to activate the components. If the LED turns green in the buzzer, stop the test to check whether the components are defective, or make sure the components rated current is higher than the rated current of this tester
- 【Wide Application】The car circuit tester is suitable for diagnostic of all 6V-24V automotive electrical systems, and works well on cars, trucks, boats, trailers, motorcycles, airplanes. Portable and ergonomic design of the car circuit probe is convenient for use in tight spaces. 4 meters extension cord is useful for mobile maintenance work. Strong bite force clip is not easy to fall off, giving you a better experience
- High Quality: The circuit probe has overload power off protection. When the current or load is too large during the distribution process, or when the current is over 7A, it will automatically disconnect and protect the battery and provide buzzer alert. Short-circuit protection allows you to test ground failures instantly. The insulation used in this electrical tester has passed the safety and reliable CCC National Safety Obligation Certification
- 【3 YEAR WARRANTY AND LIFETIME MAINTENANCE】For damage caused by human factors, AUTOOL promises to resend parts free within 3 years. If you have any requests, please contact us. We will reply you within 24 hours
