Features and Benefits

• Delivers the core Power Probe III functionality technicians already trust, enabling direct power and ground application to components for rapid functional testing
• This capability allows technicians to quickly verify component operation, isolate faults, and reduce diagnostic time, improving overall shop efficiency and confidence in repair decisions
• Accurately measures resistance values as low as 1 ohm and as high as 25K ohm's across circuits and components
• This enables precise identification of high-resistance conditions, poor connections, and failing components that may not be detected through voltage testing alone
• Actively loads circuits (+ or -) to verify wiring integrity under real-world conditions. Provides up to 0.5A load on 12V systems and 1A load on 24V systems to expose weak connections, corrosion, or damaged wiring
• Pass/Fail indication is based on a 0.5V voltage drop threshold from battery voltage if voltage drops more than 0.5V under load, audible and visual indicators are disabled, clearly signaling a wiring fault
• (voltage drop values may vary on the size and length of wires, refer to the voltage drop charts as a close example to most accurately predict acceptable voltage drop values
• NOTE: The charts are an estimation based off perfect world scenarios, results may vary)
• Integrated self resetting 10-amp circuit breaker provides increased current capacity for testing higher-load components while protecting both the tool and vehicle circuits. Ideal for powering motors, actuators, and other demanding electrical loads safely.
• Electronically actuated latch allows technicians to apply either momentary or continuous 12V power or ground without holding the switch. This feature enables hands-free operation during extended testing, component activation, or dynamic troubleshooting.
• Replaces traditional alligator clamp with a 4mm banana jack interface for improved reliability and versatility.
• Allows seamless use of extensions, adapters, and test leads while providing a more secure, consistent ground connection in demanding diagnostic environments.
• Features a proprietary 4mm locking banana jack system that securely locks Power Probe accessories in place.
• This ensures reliable electrical connections, prevents accidental disconnection during testing, and maintains PowerProbe-to-PowerProbe accessory compatibility for consistent performance.
• Powerlock technology still allows for the use of any 4mm banana jack accessory universally like all previous generation Power Probe circuit testers.
