PowerScan Automotive Circuit Tester, 12-24V Power Circuit Probe Tool Electrical Short Open Breaker Finder, AC/DC Voltage Current Resistance Detection, Trailer Light Test, 20FT Extension Cord

**2026 ALL-IN-ONE POWER CIRCUIT TESTER KIT---ACCURATELY** This Circuit Tester is the most accurate power circuit probe tester available, testing all 6-30 volt vehicle electrical systems. It supports Voltage & Polarity TestContinuity TestSignal Circuit TestComponents ActivateCheck Bad GroundingLocate Short CircuitsCircuit Breaker Protection, and more. Additionally, this Power Circuit Tester features long Cables (itself 20ft & extra 20ft cable) and comes with a cigarette lighter plug. An intuitive interface with ergonomic design makes it an ideal gift for all novice drivers or professional circuit repairers. **ADVANCED FOUR WORKING MODE---INTUITIVE & EASY** Four working modes make circuit detection more straightforward.

DC Voltage, AC Voltage, Resistance, Tone On/Off. 1) DC Voltage mode reads DC voltage with 0.1V resolution. 2) AC Voltage mode captures Min & Max voltage, duty cycle, and frequency quickly. 3) Resistance mode measures resistance between the tip and auxiliary ground wire. 4) The unique Tone On/Off Design is especially helpful in dim areas, allowing you to judge circuit voltage by the volume of the sound. **COMPONENT ACTIVATION & TEST** This automotive power circuit probe tester can activate components on/off-board electrical systems or equipment, designed for car technicians or car enthusiasts.

By activating the signal generated by the component, you can accurately determine whether the component is intact, such as blower motor, power window motor, windshield wiper, rear window defroster, lights, radiator fans, fuel injectors, etc. This circuit tester automotive tool can activate components in your hand, in the vehicle, or with ground, etc. **INSTANT IDENTIFY POLARITY** This Car Circuit Tester instantly checks component continuity and quickly identifies positive, negative, and open circuits. When the positive terminal is connected, the red LED lights up with beep sounds.

When the negative terminal is connected, the green LED lights up with a low tone. If there is an open circuit, neither LED will light. The indicator light serves as a thoughtful working guide to facilitate smooth detection operations. **CONTINUITY TEST, SIGNAL CIRCUIT TEST** This Electrical System Probe Tester can test the state of sensors, quickly and accurately judging circuit connectivity by transmitting signals, performing continuity tests. Two ways to
test continuity:
1: In resistance mode, if the resistance is 0.0 and the LED lights up, it indicates continuity.
2: Power up the connection using the power switch; if the circuit breaker trips, it means the resistance is low and continuity exists. **TRACKING & LOCATING SHORT CIRCUITS, OVERLOAD PROTECTION** This Electrical System Tester utilizes highly sensitive probes for fast and accurate detection. This power circuit probe tester can troubleshoot car wiring circuits, accurately locating faulty wires and their fault points, saving considerable time. It features built-in short circuit protection. If overloaded, its internal circuit breaker will trip to ensure user safety and extend the tester's service duration. **20FT EXTENSION CABLE, BUILT-IN FLASHLIGHT** This automotive electrical tester comes with an extra 20ft extension cable in addition to its own 20ft cable, allowing access to any position of the vehicle for testing. Ideal for trailer wiring, it can be tested along the vehicle without needing to find a suitable ground point. The built-in flashlight is convenient for detection, even in dark or dim environments, providing excellent visibility for those working at night. **NO. 1 RECOMMENDED BY ELECTRICAL MASTER MECHANIC** This automotive electrical tester is a great addition to any toolbox and is recommended by millions of automotive electrical specialists.

This power circuit probe kit performs everything P. P. 3/P. P. 4 does at half the cost, even outperforming snap-on tools
