All-in-One Power Circuit Tester for 6–30V Systems: The ANCEL Electrical Tester provides a complete solution for diagnosing vehicle electrical systems, supporting Voltage & Polarity Checks, Continuity Testing, Signal Circuit Verification, Component Activation, Bad-Ground Detection, and Short-Circuit Locating with Built-in Circuit Breaker Protection. Its clear display, intuitive interface, and extended cable setup—20ft integrated lead plus an extra 20ft extension and a cigarette-lighter adapter—allow you to work comfortably around the entire vehicle. Designed for both beginners and experienced technicians, it delivers accurate, efficient electrical troubleshooting in one versatile tool. Advanced 4-Mode Circuit Diagnostic Tool: The ANCEL PB100 Power Circuit Probe Tool combines four essential test modes—DC voltage, AC voltage, resistance, and diode—allowing you to quickly check power, trace signals, read min/max voltage, measure frequency, and verify ground and continuity with ease. Replacing multimeters, test lights, jumper wires, and fuse testers, this all-in-one probe provides fast, accurate diagnostics for most electrical issues, from battery faults to trailer lights and relays. Component Activation & Test: This automotive power circuit tester lets you easily activate and test both on-board and off-board components. It supports a wide range of vehicle systems, including blower motors, power window motors, windshield wipers, rear window defrosters, lights, radiator fans, and fuel injectors. By sending the required signal to each component, you can quickly determine whether it is functioning properly. Designed for both professional technicians and DIY enthusiasts, the tool works handheld, in-vehicle, or with grounded connections, providing fast, accurate diagnostics and making electrical troubleshooting simple and reliable. Short-Circuit Tracking & Overload Protection: Equipped with high-sensitivity probes, this ANCEL electrical system tester quickly tracks wiring issues and pinpoints short circuits or faulty wires, save serious troubleshooting time. Its resettable 10A circuit breaker protects both you and your vehicle by cutting power and triggering a buzzer when an overload occurs. When tripped, the tool will not conduct battery current to the tip until reset—helping you avoid blown fuses and unnecessary repair costs. Quickly Identify Polarity with a Highly Sensitive Probe: The ANCEL PB100 Automotive Circuit Tester instantly checks component continuity and identifies positive, negative, and open circuits. When the positive terminal is connected, the red LED lights up with a beep; when the negative terminal is connected, the green LED illuminates, accompanied by a low-pitched beep. Open circuits show no LED indication. Using red/green LEDs (active within ±0.8V) alongside the LCD display, the PB100 enables fast circuit detection, turning a simple polarity check into a reliable diagnostic tool. Continuity & Signal Testing: The ANCEL Electrical System Probe Tester quickly checks sensor operation and accurately verifies circuit continuity. It offers two easy testing methods: 1. Resistance Mode – A reading of 0.0Ω with the LED on confirms continuity; “OL” indicates an open circuit. You can even pierce wire insulation to test without disconnecting; 2. Power Switch Method – Apply power to the circuit; if the breaker trips, it signals low resistance and confirms continuity. Perfect for diagnosing broken wires, checking ground quality, and troubleshooting vehicle electrical systems with speed and confidence. 20-FT Extension Cable & Cigarette Lighter Plug: Unlike ordinary power testers, the ANCEL Automotive Power Circuit Probe Tester comes with a 20-ft cord plus a 20-ft extension cord. It can be powered via the cigarette lighter and features an alligator clip for convenient ground connections, allowing you to test electrical circuits anywhere around long vehicles or trailers. With the extra cigarette lighter plug, there’s no need to open the hood to connect the battery, so you can easily and quickly perform in-vehicle circuit testing. Dual LED Lights & LCD Color Display: The PB100 power tester features built-in dual LED lights to support work in low-light conditions or at night. It also includes a backlit LCD color display with 0.1V resolution, providing clear, easy-to-read digital readouts day or night. The easy-to-read AVO meter allows you to measure voltage, current, and resistance with precision. Top-Ranked Automotive Electrical Tester: The ANCEL PB100 power circuit probe is one of the most versatile automotive electrical tools on the market—highly recommended by auto electrical specialists worldwide. It delivers all the functionality of premium testers like the P.P.3 and P.P.4, but at nearly half the price! The ANCEL Electrical System Probe Tester comes with a 30-day free refund and exchange policy, a 1-year warranty, and 24/7 professional customer support.
