Autel PS100 PowerScan Electrical Automotive Circuit Tester

You can tackle vehicle electrical diagnostics faster with the Autel PowerScan PS100, a compact 12V/24V circuit tester built for real-world reliability.

• Test voltage, polarity, continuity, and signal circuits across 12V and 24V systems after a simple battery hook-up, with clear red/green polarity LED feedback.
• Activate components in your hand, in the vehicle, or with a ground reference to isolate faults quickly and reduce diagnostic time.
• Verify trailer lights, wiring connections, and ground integrity to prevent mis-wiring, dead circuits, and roadside surprises, especially on trailers.
• Four advanced modes—DC voltage with 0.1 V steps, AC voltage (min/max, frequency, duty cycle), resistance, and continuity—cover versatile, in-depth diagnostics.
