OBDResource CP30

Heavy-Duty Automotive Circuit Probe & Power Diagnostic Tool

Product Overview

The OBDResource CP30 is a professional-grade automotive circuit probe designed for reliable diagnostics across both 12V and 24V electrical systems. It delivers fast, accurate power and circuit testing for technicians working on passenger vehicles, trucks, diesel vehicles, and commercial fleets.

Built for real workshop environments, CP30 focuses on dependable power diagnostics rather than unnecessary complexity.

Product Positioning

The CP30 is designed as a mid-to-advanced circuit probe within the OBDResource lineup. It offers significantly more capability than entry-level probes while remaining streamlined and intuitive for daily professional use.

This makes CP30 the ideal choice for technicians who frequently work with 24V systems but do not require advanced signal analysis tools.

Why Choose the OBDResource CP30

Many circuit probes claim broad compatibility, but few are engineered specifically for heavy-duty electrical systems. The OBDResource CP30 is purpose-built to handle higher voltage environments and real-world diagnostic demands.

It provides technicians with direct control and clear visibility of power circuits, helping reduce diagnostic time and improve accuracy.

Core Functions

Power Circuit Testing

The CP30 functions as a true power circuit probe, allowing technicians to verify power and ground instantly, identify circuit polarity, and confirm whether a circuit can deliver sufficient current under load. It also enables safe power application for component verification.

This makes it ideal for diagnosing truck electrical systems, diesel vehicles, trailer wiring, and auxiliary power circuits.

Polarity and Ground Identification

The CP30 allows fast identification of positive and negative polarity and verification of solid ground connections. This helps detect unstable or floating grounds that commonly cause intermittent electrical issues.

Continuity and Circuit Integrity

The CP30 enables quick continuity testing to identify open circuits, broken wires within harnesses, and failed switches or connectors. This helps technicians confirm circuit integrity before replacing components.

Component Activation

The CP30 supports controlled component activation, allowing technicians to apply power directly to motors, relays, solenoids, and lighting circuits. This helps separate component failures from wiring or control issues, reducing unnecessary part replacement.

Built for Heavy-Duty Applications

12V and 24V System Support

The CP30 supports both 12V and 24V electrical systems, making it suitable for passenger vehicles, trucks, diesel vehicles, and commercial fleets. It performs reliably in environments where many standard probes struggle.

Electrical Protection

Internal protection features help safeguard vehicle electrical systems and the tool itself during diagnostic procedures. This reduces the risk of accidental short circuits or excessive current draw during testing.

Workshop-Ready Design

The CP30 features a balanced handheld design suitable for extended diagnostic sessions. Clear visual indicators allow fast interpretation of results, and the rugged construction supports daily professional use.

Tool Comparison

Compared to basic circuit probes, the CP30 offers true 24V compatibility, polarity identification, continuity testing, and controlled component activation. Compared to a multimeter, it delivers faster workflow efficiency and safer live-circuit diagnostics.

Typical Diagnostic Applications

The CP30 is commonly used for diagnosing no-start conditions, intermittent power loss, trailer lighting failures, relay and motor faults, and ground-related electrical issues.
