  • Find faults voltage checks can miss by applying a controlled load to positive or negative circuits to reveal excessive voltage drop, high resistance, corrosion, and weak grounds.
  • Apply 12V or 24V power or ground directly from the probe to activate motors, lights, relays, solenoids, and other electrical components.
  • Diagnose more from one tool with DC voltage measurement, resistance testing, Min/Max capture, continuous power/ground latching, and self-resetting circuit protection. Power Probe
Product description

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.

Load the circuit. Expose the fault.

PowerFlow™ circuit loading

Actively load both the power and ground sides of a circuit through a controlled 25Ω load to verify wiring under real operating conditions. PowerFlow helps uncover voltage drop and high-resistance connections that can look normal during an unloaded voltage test.

Power & ground at the tip

Supply 12V or 24V battery power or ground directly through the probe to activate components and verify operation on the spot. A built-in electronic latch can maintain continuous power or ground without holding the actuator.

Voltage, resistance & signal diagnostics

Measure DC voltage up to 60V, resistance up to 25kΩ, and capture changing or intermittent electrical conditions with additional signal and peak-measurement modes.
