## Description

Power Circuit Probe Tester 6V-24V DC Test Light Automotive Circuit Tester 12V Auto Electrical Tester 12 Volt Component Activation, Polarity Identify, with LED Light, 13FT Cable, Overload Protection

## Features

- 【Short Circuit Following and Locating Test Light】Power circuit probe tester is suitable for diagnostic in all 6V to 24V DC vehicle electrical systems. It can check switches, relays and the on-off of diodes, fuses and circuits, which can help you reduce diagnostic time in automotive electrical systems. In most cases, short circuit or instant overload of component will lead to blown fuse or circuit breaker tripping. Car test light can assist you tracing problem wires and locating breaking points.
- 【Polarity Identification & Continuity Testing & Jumper Lead Operation】This power circuit probe tester can help you quickly identify positive and negative polarity of electric cables and plugs of vehicles. When the probe tip contact to the positive electrode, the RED light on. When the probe tip contact to the negative electrode, the GREEN light on. This 12V tester can also test for continuity and do the jumper lead operation with the assistance of its auxiliary ground lead.
- 【Activate and Test Components In/Out of Vehicle’s Electrical System&Poor Ground Contact Testing】Power circuit probe tester can activate components in and out of vehicle’s electrical system, test and check the components if defective or not,or if rating current of component is higher than that of the automotive circuit tester. For some components,the negative terminal is required to be well grounded to cope with the flow of large currents, electrical tester is a good tool to test their grounding.
- 【13FT Long Extension Cable&LED Light Prompt&Buzzer Warning&Highly Sensitive Probe&Clips with Strong Bite】The cable length of the circuit tracer is 4m(13ft), which allows you access and test any electrical system easily.The LED indicator and buzzer warning can help you clear problems at a glance. Test light automotive adopts advanced high sensitivity probe, which provides you quick and accurate detection. Its clips with strong bite force which not easy to fall off, providing you better experience.
- 【Quick Self-Test & Overload Protection】Before you test a circuit or component, 12 volt tester can perform a quick self-test to ensure your tool is in good condition.Equipped with overload protection, when the current exceeds 7A, automotive circuit tester will disconnect the current automatically and give you a buzzer prompt.You can test poor ground contacts directly. Note: This electrical tester can not be used for 110/220V systems, it is only used for DC 6-24V systems. Do not use on AC voltage.
- 【Automatic Reset Test Light】When the circuit breaker trip is detected, the power circuit probe tester will sound a prompt to remind you that there is a short circuit problem. Then it will automatically reset within 3 to 5 seconds(the prompt sound will automatically turn off), so you can retest or go to test other places.
- 【Easy Operation Circuit Tester】Unroll the leads. Clamp the red clip of the power circuit probe tester to the positive terminal of the vehicle's battery. Clamp the black clip to the negative terminal of the vehicle's battery. After a simple hook-up of the circuit tracer to the vehicle's battery, automotive technician can conduct a positive or negative battery current to the tip by rocking the power switch forward or backward.
- 【3-Year Product Service】We aim at trying our best to offer you the best product and services to make you unworried before/after the purchase. We promise 3 years warranty. For quality problems caused by non-human damage, please feel free to contact us. We will provide free replacement power circuit probe tester after confirmation.
