🔹【Multi-Function Automotive Circuit Tester】
The OBDResource CP10 is a professional-grade circuit probe tester designed to diagnose electrical issues in 12V to 24V vehicle systems. Key functions include:
Voltage detection
Component activation
Diode testing
Ground fault detection
Short circuit tracing and location
Polarity (positive/negative) identification
With a 16.5 ft (5m) cable, the CP10 allows you to reach virtually any area of the vehicle with ease.
🔹【LCD Display & Built-in Flashlight】
Equipped with a clear LCD display, the CP10 accurately measures and displays voltages from 0 to 80V. The device also features a built-in LED flashlight, activated by simply connecting the red and black clips to the battery terminals, making it ideal for working in low-light or confined spaces. This added light also serves as a practical utility feature during emergency repairs.
🔹【Component Activation & Voltage Testing】
Before activating vehicle components, the CP10 performs a quick self-test to ensure the tool is functioning properly. Once verified, it can activate a wide range of components, such as:
Starter motors
Solenoids
Fuel pumps
Cooling fans
Headlights
This functionality helps you verify component integrity without the need for separate tools.

The CP10 supports continuity testing, enabling you to check if an electrical path is complete. This is especially useful for:
Diagnosing broken wires
Identifying open circuits
Troubleshooting faulty switches or relays
Quickly identifying such issues allows for more efficient and accurate electrical repairs.
🔹【Short Circuit Tracing & Diode Testing】
The CP10 excels at tracing and pinpointing short circuits, helping users locate faults in wiring or components efficiently. Additionally, the integrated diode testing function sets it apart from other testers on the market—offering more versatile diagnostic capabilities and saving both time and repair costs.
🔹【Ground Fault Testing & Jumper Wire Simulation】
This device supports ground testing and includes a jumper lead function to verify the integrity of ground connections and power circuits. The built-in LED light at the probe tip provides clear illumination of your workspace, enhancing usability in dark or cramped areas.
