Car Circuit Tester Power Probe Automotive Diagnostic Tool 12V 24V Electrical

This professional automotive circuit tester is an essential tool for diagnosing electrical issues in any vehicle. Quickly and accurately check voltage and positive/negative polarity with a simple touch.

Key Features for Easy Diagnostics

• Accurate Voltage Measurement: Connect the tool to your car's power supply; the display illuminates white and shows 0V. When the probe contacts a live positive circuit, the digital screen instantly displays the current circuit voltage.

• Simple Polarity Identification (Positive/Negative Detection):

  • Positive Circuits: Screen displays voltage and lights up white.

  • Negative/Ground Circuits: The display illuminates green, shows 0V, and the device sounds an audible beep for quick confirmation.

• Versatile Testing: If the device's power source is separate from the circuit you're testing (e.g., bench testing components), simply connect the device's ground lead to the circuit's negative terminal for reliable results.

This car electrical tester is perfect for mechanics, automotive enthusiasts, and DIYers needing a reliable car voltage meter and polarity checker.
