The Power Probe PP3PF with PowerFlow Technology is designed to help technicians diagnose electrical issues in 12V and 24V vehicle systems. Its PowerFlow circuit-loading technology allows users to test positive and negative circuits under load to identify voltage drops, high resistance, weak grounds, and poor connections. The tool can apply battery power or ground directly to components, measure resistance up to 25 kΩ, and activate electrical components. Additional features include a 10A solid-state circuit breaker, electronic latch function, and quick-connect ground lead.
