PS100PRO Automotive Electrical Circuit Tester | Power Circuit Probe, Component Activation & Short Circuit Location Tool

PS100PRO Automotive Circuit Tester

Professional Power Circuit Probe with Component Activation

Product Overview

The PS100PRO Automotive Circuit Tester is a professional power circuit probe designed to simplify and accelerate automotive electrical diagnostics. Built for 12V and 24V vehicle electrical systems, it allows technicians to quickly identify power, ground, continuity, open circuits, and short circuits — while also enabling direct component activation without jumper wires.

Designed for professional mechanics, technicians, and serious DIY users, PS100PRO delivers fast, accurate, and confident diagnostics in real workshop environments.

Key Features

Power Circuit Testing

The PS100PRO functions as a true power circuit probe, allowing instant verification of power and ground conditions. It clearly identifies positive, negative, and open circuits, helping diagnose electrical faults quickly and safely.

Component Activation

With controlled power output at the probe tip, PS100PRO allows direct activation of electrical components such as lights, relays, motors, and solenoids. This makes it easy to confirm whether a component is functional without relying on ECU commands or jumper wires.

Short Circuit and Ground Fault Detection

The PS100PRO helps locate short circuits, poor ground connections, and wiring faults efficiently. By tracing electrical paths, technicians can pinpoint problem areas faster and reduce unnecessary disassembly.

Continuity and Circuit Integrity Testing

Quickly verify wiring continuity and circuit integrity across harnesses, switches, connectors, and loads. This ensures accurate diagnosis before replacing components or performing repairs.

Built for Professional Use

Designed for daily shop use, the PS100PRO features a durable construction, long test lead, and ergonomic handheld design. Integrated illumination improves visibility in low-light engine bays and under-dash environments.
