About this item

• 🩺【2025 ALL-IN-ONE POWER CIRCUIT TESTER KIT】ANCEL PB100 Powerprobe is most accurate power circuit probe tester yet, test all 6-30 volt vehicle electrical systems. It supports ✅Circuit Open Test ✅AC/DC Voltage Test ✅Diode Test ✅Resistance Test ✅Polarity Test ✅Continuity Test ✅Ground Test ✅Activate Components ✅Signal Circuit Test ✅Fuse, Trailer Light Test. You can quickly & easily locate short circuits, broken wires, and even trace wires. Besides, ANCEL Power Circuit Tester has extra long Cables (itself with 20ft, and extra with 20ft cable), it's got a Cigarette Lighter Plug and Battery Hookup Clips for easy power access.
• 🚀【ADVANCED FOUR WORKING MODES—INTUITIVE & EASY】The PB100 power circuit probe tester four working modes make circuit detection more simple. DC Voltage, AC Voltage, Resistance, and Diode. ✅DC Voltage mode can read DC voltage with 0.1V resolution. ✅AC Voltage can get Min & Max voltage, duty cycle and frequency quickly. ✅Resistance mode to read resistance between tip and auxiliary ground wire. ✅Diode Test Mode is not only used for basic on-off testing, but also for quickly diagnosing complex circuit problems by measuring Forward Voltage Drop and determining one-way conductivity.
• ⚡【COMPONENT ACTIVATION & TEST】This ANCEL PB100 automotive circuit tester supports activating components. By activating the signal generated by the component, you can accurately judged whether the component is intact, such as blower motor, power window motor, windshield wiper, rear window defroster, lights, radiator fans, fuel injectors, etc. ANCEL circuit tester automotive tool can activate component in your hand/ in the vehicle/ with ground etc.
• 🎯【SIGNAL CIRCUIT TEST&CONTINUITY TEST】When you extract Diagnostic Trouble Codes (DTCs) from the vehicle's ECU, this electrical system car circuit tester can test a variety of sensors and circuit to help you find out the root problems of the car's electrical system! Two ways to test continuity: ✅1: In resistance mode, if the resistance is 0.0Ω and the LED lights up, it means continuity. ✅2: Power up the connection using the power switch, if the circuit brea-ker tr-ips, that means the resistance is low and there is continuity.
• 🎁【Rich and Professional Accessories】This ANCEL PB100 power prob with a 20Ft Built-in Cable, Whether you're dealing with a dinky compact or a massive truck, It allows you to reach from the front to the rear of the vehicle; Included Replacement Probes, mean you’re never dead in the water if one goes MIA; Clip directly to the battery with Battery Hookup Clips or plug into the Cigarette Lighter Adapter. Your call, boss. Tossed in a Durable Storage Box that laughs at spills, drops, and garage chaos.
• 💝【5-YEAR WA*RRANTY & 24/7 ASSISTANCE】ANCEL PB100 probe tester is compatible with all 6V-30V vehicle electrical systems, such as cars, excavators, trucks, boats and motorcycles, etc. We offer 5-year warranty, Lifetime technical assistance, 60 Days No-Question-asked NEW REPLACEMENT OR REFUND.

One Product, Four Working Modes —— Fix 99% of Car Electrical Issues.

• You can access four precise diagnostic modes (DC Voltage, AC Voltage, Resistance and Diode）
• Providing efficient electrical system testing, continuity testing, signal circuit testing, voltage & polarity testing, ground testing without wasting fuses, following & locating short circuits, checking for bad ground contacts, component activation on and in the vehicle

Intelligent Sensing Sound and Light Alarm —— Your New Best Friend in Troubleshooting

• A steady, loud beep means you've got a good connection, while an absence of sound tells you right away there's a break in the circuit
• When the signal is strong, it indicates a smooth and intact line. Conversely, a weak signal or no signal at all points directly to the location of a disconnection.

Quickly Carefully Accurately —— Designed for Car Technician or Car Enthusiasts

It can quickly locate short - circuits, carefully check for open - circuits, and accurately identify electrical leakage. It's a must - have for ensuring electrical system safety and efficiency.

Procedure for Testing the M.A.P. Sensor Circuit: If the LCD Reading Is Abnormal, There is A Problem with the Sensor Circuit.

• In AC Voltage mode, employing the probe tip in conjunction with chassis ground or the auxiliary ground lead.
• Establish a connection between the vacuum pump and the MAP sensor.
• Make contact between the probe tip and the positive terminal of the MAP sensor, and monitor the LCD readings, which should manifest as a sine wave under normal circumstances.
• Apply vacuum.

COMPONENT ACTIVATION & TEST —— ANCEL PB100 can activate component in your hand/ in the vehicle/ with ground etc

• By activating the signal generated by the component, you can accurately judged whether the component is intact, such as blower motor, power window motor, windshield wiper, rear window defroster, lights, radiator fans, fuel injectors, etc.
