Autel PowerScan Automotive Circuit Tester – All-in-One 12–24V Short Finder with 20ft Extension

Meet the Autel PowerScan Automotive Circuit Tester, an all-in-one kit designed to simplify car electrical diagnostics for both enthusiasts and pros. It tackles 6 to 30 volt vehicle electrical systems and provides multiple testing modes while delivering clear guidance through LEDs and audible cues. This compact tool blends voltage checks, polarity readouts, continuity tests, and signal circuit verification with component activation and grounding checks, plus built-in safety features like circuit breaker protection. The result is a practical, ready-to-use tester that helps you pinpoint issues quickly without requiring a separate toolbox of gadgets.

Four working modes make circuit detection intuitive. In DC Voltage mode you read voltage with a precision of 0.1 V. In AC Voltage mode you capture min and max voltage, duty cycle, and frequency. Resistance mode measures the path between the tip and ground. The Tone On/Off option provides audible feedback in dim or noisy environments, helping you stay focused on the task at hand.

The kit shines in real world use. Its long cables offer generous reach around the vehicle and can even assist with trailer wiring. A built-in flashlight illuminates dark spaces for better visibility. The ability to activate components on or off the electrical system helps verify operation of items such as blower motors, power windows, windshield wipers, defrosters, and more. Instant polarity checks show red LED when positive and green LED when negative, with audible cues to support your workflow. If a short or overload is detected, the internal circuit breaker trips to protect you and the tester.

Beyond testing, this Autel tool delivers practical value for frequent repairs. The ergonomic design stays comfortable in hand during longer sessions, and the two 20 ft extension cables maximize reach where ground points are hard to locate. The package includes dependable support and a one year warranty, with a 30 day return policy for peace of mind.
