What it is
Five tests. One trusted tool.
Power Probe PP3+ builds on the legendary PP3 platform by adding integrated resistance measurement. Apply power and ground, test voltage and polarity, verify continuity, and now measure resistance — all from a single diagnostic tool. Built for professional technicians to locate electrical faults faster, verify component health with greater accuracy, and carry fewer devices into the bay.
// Function 01
Power & Ground
Activate motors, relays, lights & solenoids — no jumper wires
// Function 02
Voltage & Polarity
Identify power, ground & open circuits in seconds
// Function 03
Continuity
Verify wiring, switches, relays & connections
// Function 04
Resistance
Measure 0Ω–25kΩ to pinpoint high-resistance faults
Features & functions
- New resistance mode measures 0Ω–25kΩ to find corroded connections, damaged wiring and failing components that voltage tests can miss
- Supply 12/24V DC power or ground to instantly activate relays, motors, lights and solenoids without jumper wires
- Voltage & polarity testing identifies power, ground and open circuits with clear visual and audible indicators
- Continuity testing verifies wiring integrity, switches, relays and connections without switching tools
- Min/Max voltage capture detects voltage drops and intermittent faults standard voltmeters miss
- Integrated circuit tester and ohmmeter in one rugged body — fewer devices on the bench
- Digital display delivers real-time voltage and resistance readings for confident diagnosis
Resettable protection: an 8-amp thermal circuit breaker with manual reset protects the tool and the vehicle circuits — keep working without replacing fuses.

What's in the box
1× PP3+ Circuit Tester · 1× 20 ft power cable · 1× probe tip · 1× battery clip set · 1× alligator clip
Why upgrade
Voltage testing alone
- Voltage tells you power is present — not why a circuit is failing
- High-resistance & corroded connections frequently go undetected
- Requires a separate multimeter to check component resistance
- More tool-switching means slower, less consistent diagnosis
PP3+ with resistance testing
- Power, ground, voltage, polarity & continuity — all in one tool
- Measures resistance 0Ω–25kΩ directly from the diagnostic tool
- Pinpoints corrosion, damaged wiring & failing components fast
- Integrated circuit tester + ohmmeter — no second device needed
