Car Ignition Coil Tester, Ignition Coil Tester/Spark Plug Tester with LED Diagnostic, Relay Tester for Auto Solenoid Valve Engine Analyzer

★ Tester wake-up function introduction:When the microcontroller detects no signal for 20 seconds, the indicator light will turn off. When testing is required again, simply bring the tester close to the device to be tested, and the instrument will automatically start the test state upon detecting the signal.★ Specifications:Material: plasticSize: 152 x 25 x 18 mmWeight: 71gVolatge: 3V★ Package Included1 x Car ignition coil tester2 x AAA Battery

• ★ Reliable: Made from high-quality ABS material, auto spark plug and coil tester offers excellent mechanical stability and corrosion resistance, manufactured to professional standards for high accuracy and reliability, with an LED light at the tip to illuminate dim areas
• ★ Practical Function: This automotive tester uses advanced technology to capture and analyze signals under non-disassembled automotive electrical components. Without disassembling the car components, the test pen will collect and analyze the signals and display the test results through the LED indicator and buzzer, which can easily detect whether there is any fault in the car's electronic components.
• ★ Convenient to Use: This car ignition tester is simple and easy to use. First of all, you should find the correct position of the positive and negative battery terminals and push the button to push it out. Next, you need to install the battery and cover it, and then press the button to open it. Finally, you just need to turn on the power and press the blue button to find the trouble spot.
• ★ Test Range: Car spark plug tester tests such automotive components as ignition coils (traditional, double spark, single spark), generators, inside fan motors, solenoid or electromagnetic valves, combination valve (heating, water cooling), emission control valves, fuel injectors, spark plugs, electric relays, etc
• ★ Versatile Automotive Compatibility : Works with most 12V gasoline vehicles, including sedans, SUVs, RVs, and trucks. Great for DIY diagnostics or professional use.
