Product description

The Power Probe® PP319 combines the diagnostic capabilities of the Power Probe 3 with additional accessories for greater reach and versatility. Operating from 12–24 volt sources, it functions as a digital voltmeter with the ability to apply power and ground directly through the probe. Using the Auxiliary Ground cable, users can simultaneously supply battery voltage and ground to test components, as well as check continuity using the probe tip and auxiliary ground lead. The PP319 kit also includes a 20 ft. power cable extension, cigarette lighter adapter, and protective carrying case, making it easier to diagnose electrical systems throughout and around the vehicle.

One probe. Multiple ways to diagnose electrical problems.

Voltage, polarity & continuity

See circuit voltage on the LCD while red and green LEDs quickly identify polarity, and check continuity in wires and components.

Power & ground at the tip

Use the power switch to apply battery positive or ground through the probe tip to activate components and verify operation. The manual specifically shows applications including lights, motors, fuel pumps, solenoids, relays, and other electrical components.

Five diagnostic modes

Go beyond basic voltage testing with five modes for standard circuit testing, positive and negative peak capture, peak-to-peak measurement, and adjustable peak-detection thresholds.
