【LOCATING OPEN CIRCUIT】Open Wire Detector, powered by 2pcs*9V Batteries. It detects and alerts you immediately where a circuit is open. You can quickly and easily Locate short circuits, open connections, broken wires, current leaks and even trace wires. Transmitter and receiver LEDs show open or short circuit conditions.

【CHECKING SHORT CIRCUIT】Short Circuit Finder Automotive,you can also find intermittent circuit problems by flexing wires or connectors and listening for a change in the receiver tone, 7 inch Flexible Probe Help Reaching Wires in Congested Places.

【SUITABLE FOR DC 6~42 Volt CIRCUIT POWER】Electrical Circuit Tracer will work on all kinds of circuits with voltages between 6 and 42 volt DC. (such as those found in automobiles,trucks,tractors,boats,RVs,etc...With its wide working voltage range.).

One set of interconnect leads - length 64 inches

Test probes

Flexible silicon back probe pins

Can test circuit current up to 30 amperes - an easy way to check fuel pump amperage

Clever design allows for easy connection into fuse sockets

【Safety Non-Contact Voltage Tester】Non-Contact Voltage Tester is safer for testing all Electric Appliances in Your Family. The tester with NCV inductive probe for AC voltage Just places the tip near a terminal strip, outlet, or supply cord. When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire.

【 High-Efficiency And Convenient 】The tester with LCD display. When the voltage is detected, the alarm will send out green or red light and beep. When the higher the sensed voltage or the closer it is to the voltage source, it beeps at a higher frequency. At the same time, the screen will be red or green, red means the high voltage and live wire are detected, green means the low voltage and null wire are detected.

【DUAL RANGE/ High&Low Sensitivity】The sensitivity/flashlight key can be switched at high and low sensitivity. Detect high and low voltage (AC 12-1000V /48-1000V )Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring.

💪【Powerful Circuit Tester Kit】The P200 Automotive Circuit Tester is the only circuit tester on the market that can be upgraded, a tool for quickly testing all ✅9V-30V✅ electronic systems. It can diagnose problems in the components, electrical circuit systems or fuel injectors of the car in the shortest time. Not only the test time is greatly shortened, but also more intelligent and intuitive, suitable for any novice driver or maintenance engineer.

💪【Fuel Injector & Relay Tester】It is extremely important to regularly test the fuel injector. Damage to the fuel injector can easily lead to unstable idle speed of the engine, increased fuel consumption, causing engine shock. It is worth mentioning that TopDiag P200 auto circuit tester has been added 300+ USD valued powerful functions, namely: ✅Fuel Injector Test✅ Relay test mode. TopDiag makes diagnosing your car easier and saves maintenance costs.

💪【0~5V Adjustable Power Supply & Activating Components】0~5V power is useful when checking the wiring to the ECU/ECM, also meet the voltage requirements for the sensitive parts with low voltage. Besides positive activation, negative activation is our newest function which others none, power on components at a moment notice.
