## Description

Automotive Power Circuit Probe Kit, 12V 24V Car Circuit Tester Electrical System Tool, Digital Voltage Tester, Multimeter, Short Finder,Relay Fuse Tester,AC DC Diode Resistance Tester

## Features

- 【Widely Application】This automotive electrical system test tool is the perfect choice for automotive circuit probe tester. Unlike other circuit testers that require you to use a variety of tools to troubleshoot electrical system problem, our circuit testers are perfectly capable of performing multiple types of services such as continuity testing, component activation, fuse test, checking bad ground indicator, detect voltage and current, positive and negative power supply.
- 【Portable Quick】When the vehicle's headlights, turn signals, lift windows, sunroofs and other functions fail, our power circuit probe kit can output positive and negative power to check whether circuit components are normal, and can also perform continuity checks and resistance checks. Through these checks and diagnoses whether the path of the car circuit is interrupted, it can be found which parts of the circuit are intact, which parts are bad.
- 【Overload Protection】Our automotive circuit tester tools has a built in 10 amp circuit breaker to prevent overloading and cooking a circuit.The output current can be reversed to form a loop power, and when the current exceeds 20A, This power circuit probe will automatically trip to protect the device and extend the service life.
- 【Humanized Design】Built-in Flashlight enables you to work in the dark. Even in a dark environment where you can't see clearly, AUTOOL BT250 fuse tester automotive kit can give you a good view.
- 【LCD Color Display】Modern and outstanding LCD high-definition color display. The large backlit screen avoids situations of completing the detection in dark areas, helping car technicians, engineers or car DIYers view readings more easily. Moreover, the display screen is clearer, and the displayed data is more direct and clear.
