Jaime Lazarus demonstrates Power Probe products at ISN Tool Dealer Expo

Attendees cite Power Probe III as most frequently sold Power Probe product.

“It’s a wonderful tool for voltage and for component testing functions,” Lazarus said of the Power Probe III. “It is like a digital volt meter that has more capabilities than a DVOM.”

Technicians can even perform voltage drop tests by subtracting tip voltage from the displayed battery voltage readings, he noted. Power Probe III is short circuit protected and it serves as a continuity tester.  “It is not an ohm meter, but performs much-needed continuity tests,” he said.

Lazarus described the Hook as the next level of diagnostics from Power Probe. The Hook can perform all the functions of the Power Probe III and more. It has a multi-function, 5-way switch that provides the user more functions than the Power Probe’s “rocker” switch. The Hook works on 12V to 48V automotive electrical systems. By touching the Hook to a circuit, the screen will automatically display the right meter and the right function for the right circuit condition. It can display as a volt meter, an ohm meter and if the technician needs to activate an electrical component, the Hook displays amperage on the meter. 

The Hook can test for corroded or resistive -- ground or positive -- circuit conditions when employing the “Hot Shot” function. “Hot Shot” is useful when trying to determine the cause of intermittent circuit malfunctions.  It provides instantaneous pass or fail test results. Lazarus warned, “You don’t want to use Hot Shot on low amperage circuits. The test should be done on circuits designed for 5 amps or more.”

“The tech has a huge amount of information right in his hand when using The Hook from Power Probe” he said.

Some of the advanced Hook features include:

  • Volt meter mode
  • Ohm meter mode
  • Counter mode (which displays frequency, duty cycle, and both positive and negative pulse widths.)

Another Power Probe tool few people had heard about, the Power Probe Key Assist, allows the technician to crank the engine remotely, from under the car, the hood or from either side of the vehicle, Lazarus said. It is not necessary to have someone else crank the vehicle or to get out from under the hood to crank it when using the Key Assist. Lazarus gave a brief description of this tool and suggested attendees view the Key Assist video available on the website.
