Power Probe 3 with PowerFlow Circuit Tester (PP3PF)

The Power Probe 3 PF with PowerFlow™ Technology goes beyond basic circuit testing by actively applying a controlled load to verify wiring integrity under real-world conditions. Instantly identify weak connections, corrosion, and voltage drops that traditional testers may miss. Power components with battery voltage or ground, measure resistance from 1Ω to 25kΩ, monitor voltage up to 60V, and capture Min/Max readings—all from one versatile diagnostic tool. Featuring a built-in latch function, 10A self-resetting circuit breaker, and secure PowerLock™ connectivity, the PP3PF helps technicians diagnose electrical problems faster, more accurately, and with greater confidence.

Finding corroded or high resistance wiring
Use PowerFlow to load-test a circuit and quickly identify hidden voltage drops caused by corrosion, loose connectors, or damaged wires.

Verify Component Operation
Directly power devices like cooling fans, relays, window motors, fuel pumps, and horn circuits to determine whether the component or the wiring is at fault.

Diagnosing Lighting and Trailer problems
Test trailer connectors, brake lights, turn signals, and other lighting circuits by applying voltage and checking continuity.

Tracking down Electrical Shorts
Energize suspect circuits and follow the wiring harness to isolate blown-fuse conditions and locate shorts more efficiently.
