Power Probe 3 Circuit Tester Kit PP319FTCRED — 12–24V Diagnostic Probe with LED Voltmeter, 8A Resettable Breaker, 20ft Lead

The Power Probe 3 Circuit Tester Kit (PP319FTCRED) is a portable diagnostic tool that supplies power or ground and tests circuits, continuity, and components across 12–24 volt systems.

This compact kit brings a professional-grade troubleshooting station to the shop or roadside. The PP3 tester in this set adds DC voltmeter indicators, a resettable 8 A circuit breaker, and a continuity/component tester, all packaged with a 20-foot power lead and organized case. It’s designed to speed fault-finding, verify component operation, and safely simulate signals without juggling multiple instruments.

How does the Power Probe help diagnose vehicle electrical issues?

The Power Probe supplies a stable source of power or ground so you can energize components, trace shorts, and confirm wiring paths. LED voltmeter indicators show polarity and voltage levels instantly, helping you pinpoint faults faster than back-probing alone.

• Supplies controlled power or ground to relays, switches, sensors, and actuators
• DC voltmeter LEDs display voltage presence and polarity
• Continuity tester verifies wiring and connector integrity
• Resettable 8 A breaker prevents accidental overloads during tests

Can I use this tester on different vehicle systems and voltages?

Yes—the PP319FTCRED is compatible with both 12 V and 24 V systems, making it suitable for cars, trucks, vans, and many off-road or commercial vehicles. Its broad voltage range and long power cable let you reach battery terminals or auxiliary batteries with ease.

• Works on 12–24 volt electrical systems
• 20-foot power cable lets you access batteries and remote components
• LED voltage indicators adapt to measured voltage ranges
• Portable case keeps probes and accessories organized for mobile use

What safety and protection features are included?

Built-in safety features reduce risk while testing circuits. The self-resetting 8 amp circuit breaker prevents sustained overloads, and the kit’s design minimizes accidental shorting when applying power or ground to components.

• Resettable 8 A circuit breaker prevents damage from excessive current
• Insulated probe tips and leads reduce the chance of accidental shorts
• Clear LED feedback avoids guesswork when applying voltage or ground
• Carrying case stores accessories safely between jobs

What accessories are included and how do they expand functionality?

The kit includes a variety of leads and adaptors to test connectors, harnesses, and components in tight spots. Using the supplied accessories you can simulate sensor signals, verify continuity, and drive devices directly to observe behavior under power.

• Multiple probe tips and adaptors for harnesses and terminals
• 20-foot main power lead for flexible reach during diagnostics
• Continuity and component testing modes for on-vehicle checks
• Compact case organizes tools for quick access during service calls

Who is this for? The Power Probe 3 Circuit Tester Kit is aimed at professional technicians, fleet mechanics, and advanced DIYers who need a reliable, multi-function electrical tester for automotive and light commercial work. If you troubleshoot wiring faults, verify component operation, or perform field repairs, this kit reduces diagnostic time and helps you confirm fixes with confidence. It’s particularly useful when working on mixed-voltage fleets or when a long reach to the battery is needed.
