Review: Long wires makeas it easy to reach where ever you need, and works well. - I rather like this little tool. I bought it to install a radio in my vehicle which sadly didn't go well, this tool was a huge help in tracing all the wires, testing the radio, and figuring out if the controls were set correctly. I might have returned the radio but I'm keeping this tool on hand for sure - once I find the right radio to install I know this thing is going to make it easy to double check my work. I found the long power cable to be the most useful, it let me connect the tester to my battery and go about dropping 12v's whenever I needed it, then still turn around and find grounds, and hot wires easily.
Review: Good to have - Great value for the money. Seems to be high-quality. Easy to use and durable. Build quality is great. Nice for diagnosing ground/power issues.

## Features

- [Polarity Identify & Continuity Test] The power circuit probe tester is made to quickly identify the positive and negative polarity of the vehicle cable and plugs. When the tester touches the positive pole, the LED should turn red and the LED should turn green while it touches the negative pole. The power circuit probe tester is also used to test the continuity of switches, relays, diodes, fuses, and circuits of the vehicle
- [Wide Application & Overload Protection] This power circuit probe tester is suitable for of all 6V to 24V automotive electrical systems which works well on cars, trucks, boats, trailers, and motorcycles. The tester also has an overload protection function, When the current exceeds 7A, the circuit will automatically disconnect and give out a buzzer prompt
- [Component Activate and Test] This power circuit probe tester is perfect for professionals and car enthusiasts, which can be used to activate components inside/outside the auto electrical system and the LED indicator light makes it easy to check whether the component is defective and test whether the rated current of the component is higher than the rated current of the car test light
- [Short Circuit Tracking and Locating] In most cases, a short circuit or momentary overload of a component will cause a fuse or circuit breaker to blow. Using this auto test light can help you quickly and accurately find the faulty wire and its fault point
- [157inch Test Cable] The automotive circuit tester is equipped with a 157inch extended testing cable wire, convenient for use and storage, along with large size alligator clip for easy one hand operation, making it easy to test the entire vehicle circuit system, which will definitely improve your working efficiency
