Power Probes

The Power Probe and Power Probe II are easy-to-use diagnostic tools for car electrical systems from 6 to 24 volts. While multimeters have several functions and dials, the Power Probe only has an on/off switch, making it faster to diagnose problems with your car engine. The Power Probe II has an optional audio feature for situations where the LED is not clearly visible. If you are not familiar with the electrical component of a car engine, you will need some help in diagnosing your problem.
