Features

  • All-in-One Power Circuit Tester for 630V SystemsThe 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 setup20ft integrated lead plus an extra 20ft extension and a cigarette-lighter adapterallow 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 ToolThe ANCEL PB100 Power Circuit Probe Tool combines four essential test modesDC Voltage, AC Voltage, Resistance, and Diodeallowing you to quickly check power, trace signals, read min/max voltage, and measure frequency, or verify ground and continuity with ease. Its intuitive buzzer function helps identify circuit conditions even in dark or tight spaces. Replacing multimeters, test lights, jumper wires, and fuse testers, this all-in-one probe gives you fast, accurate answers for most electrical issues, from battery faults to trailer lights and relays.
  • Component Activation & TestThis automotive power circuit tester lets you activate and test on-board and off-board components with ease. 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 hand-held, in-vehicle, or with grounded connections, providing fast, accurate diagnostics and making electrical troubleshooting simple and reliable.
  • Short-Circuit Tracking & Overload ProtectionEquipped with high-sensitivity probes, this ANCEL electrical system tester quickly tracks wiring issues and pinpoints short circuits or faulty wires to save serious troubleshooting time. Its resettable 10A circuit breaker protects both you and the vehicle by cutting power and sounding a buzzer when overload is detected. When tripped, the tool will not conduct battery current to the tip until resethelping you avoid blown fuses and unnecessary repair costs.
  • Quickly Identify Polarity & Highly Sensitive ProbeThe 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 with a low-pitched tone. Open circuits show no LED indication. Using red/green LEDs (active within 0.8V) alongside the LCD display, the PB100 enables fast voltage detectionturning a simple polarity check into a reliable diagnostic tool.
  • Continuity & Signal TestingThe 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 0.0 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.
  • 20FT Extension Cable & Cigarette lighter PlugUnlike the ordinary power tester, ANCEL Automotive Power Circuit Probe Tester comes with 20 feet long cord plus 20 feet extension cord. Combining the feature that it can be powered by the cigarette lighter, and alligator clip for convenient ground connection, you can test electrical circuit system anywhere around the longer vehicles and trailers. Extra cigarette lighter plug, no need to open the hood to connect the battery, so you can easily and quickly conduct in-vehicle circuit testing.
  • Dual Headlights & Intuitive Backlit LCD DisplayTo be a proper solution for nighttime testing jobs, the PB100 power tester comes with a lighting function to support your testing needs in a low-light environment. What's more, this PB100 Circuit Light Tester with highly clear LCD digital backlit display screen, a resolution of 0.1V, clear & visible digital readouts for day and night. Easy to read AVOmeter allows you to read voltage, current and resistance at the fingertip.
  • Top-Ranked Automotive Electrical TesterThe ANCEL PB100 power circuit probe is one of the most versatile automotive electrical tools on the markethighly recommended by auto electrical specialists worldwide. It delivers all the functionality of premium testers like the P.P.3/P.P.4, but at nearly half the price! ANCEL Electrical System Probe Tester provides 30-day f*ree r*efunds & ex*changes, 1-year w*arranty, 24/7 professional customer service.

  • great diagnostic tool
Model: PB100
This is a great diagnostic tool to have in your tool bag. The long extension cable gives you enough length to reach the rear of vehicle or a trailer to test trailer lights. Being able to apply power and ground and the longer cable are the main reasons that I purchased this.

  • Simple to Use - Bright LCD - Audible and Visual Notifications
Model: PB100
This is the second circuit tester kit I have purchased. The first one I found very useful in tracking down pesky electrical problems, but usually didn't have it handy when I was traveling and visiting repair shops while at work. So, I bought this ANCEl PB100 Vehicle Circuit Probe Kit to carry with me while the other stays at home. Included in the circuit tester kit were all the items included in the description including: *1 PB100 Circuit Probe *1 Probe Tip *1 Extension Cable (20ft) *1 Set Battery Clips *1 12-Volt Adapter *1 Case *1 User's Manual The PB100 is powered from the battery voltage of the circuit you are testing so no internal batteries are needed. To use you just clip the alligator clips to the source battery or use 12-Volt Adapter and DC Voltage immediately shows on the backlit colored LCD screen. (To verify source voltage just touch the probe to the positive lead of the vehicle's battery or press the toggle switch forward.) Pressing the orange button on the tester toggles between the different functions of the tester. 1) DC Voltage (with a resolution of 0.1 volts) 2) AC Voltage (shows Max. Voltage, Min. Voltage, and frequency) 3) Resistance Mode (Ohm's, for reading resistance between the probe tip and auxiliary ground lead) 4) Diode Mode (for checking forward and reverse bias) There is also a toggle switch that is used to apply source voltage to a circuit (press forward) or provides a direct ground (press backward). I would caution anyone to use extreme caution when using this function as it would be easy to destroy electronic components if used incorrectly. A couple of thing I like about this tester is the two LED work lights on the front come on automatically when the probe is hooked up to a 12-volt power source. This tester also gives you an audible notification when testing circuits along with a visual notification. (explained below) *Red Light / Single Beeps: Near source Voltage is delectated or source Voltage (toggle) is being applied. *Green Light / Mutiple Beeps: Less than source Voltage is detected or a Ground (toggle) is being applied. Overall I like this ANCEl PB100 Vehicle Circuit Probe Kit very much, this type of tester should be part of any mechanic's or electronic tinkerer's arsenal. If I experience any issues I will update this review. ... show more
