Autel PowerScan PS100 Automotive Electrical Circuit Tester

Autel PowerScan PS100 Automotive Electrical Circuit Tester

The Autel PowerScan PS100 is a dedicated automotive electrical circuit testing tool for diagnosing wiring, power supply, grounding and component faults. Unlike a diagnostic scan tablet, the PS100 is intended for hands-on electrical testing at connectors, switches, relays and circuits, helping technicians confirm whether power and ground are present and whether components respond when safely energised.

Key Features & Diagnostic Capabilities

• Built-in voltmeter functionality for checking circuit voltage at the test point.
• Power and ground injection controls can energise suitable components directly, assisting with controlled actuator and wiring checks.
• Instant polarity indication helps identify positive, negative and open circuits.
• Continuity testing supports tracing wires, switches and connections.
• Ground testing assists with diagnosing high-resistance or poor earth connections.
• Short-circuit indication and circuit-breaker protection help during electrical fault finding.
• Integrated work light assists when working under dashboards and in engine bays.
• Long vehicle-powered test lead gives access to different parts of the vehicle.

Workshop Applications

• Confirm feed and ground at relays, motors and actuators.
• Check continuity of wiring harnesses and switches.
• Investigate poor grounds, open circuits and suspected shorts.
• Power a compatible disconnected component for functional testing, following the vehicle manufacturer’s safety procedure.
• Supplement a scan tool during diagnosis of electrical faults.

Technical Specifications

• Vehicle-powered operation using 12V or 24V vehicle supply, as stated in the original listing.
• Colour TFT display, 160 × 128 resolution.
• Operating temperature approximately 0–60°C.
• Circuit-breaker-protected lead, approximately 20ft long.

Package Contents

• PowerScan PS100 electrical circuit tester.
• Vehicle power connection and test lead assembly.
