The Power Probe 3 is a Digital Voltmeter designed to work on 12-24 Volt sources, with the ability to apply Power and Ground. Using an Auxiliary Ground cable, the user can simultaneously supply Battery Voltage, and ground to test components or to simply test for continuity. The PP3 is protected by an 8 Amp Circuit Breaker.
