About this item

• 【Most Cost-Effective Circuit Tester】ANCEL PB100 power circuit probe tester is the best electrical tester to reduce diagnostic time for all 6-30V vehicle electrical systems. It quickly locates shorts, checks bad grounds, traces broken wires, tests voltage/polarity/continuity/signal circuits, and inspects trailer lights and connections. Activate components without disassembly - diagnose blower motors, fuel pumps, and relays etc. in seconds. Save hours of guesswork and get precise results.

• 【4 Pro-grade Working Modes】ANCEL PB100 circuit tester can be used as a test light/multimeter/ohm meter/circuit breaker finder, providing 4 essential diagnostic modes for comprehensive electrical testing. DC Voltage (0.1V precision for detecting subtle voltage). AC Voltage (Measures max/min voltage and frequency for accurate sensor diagnostics). Resistance (Auto-ranging measurement (0.1Ω - 100KΩ) between probe tip and auxiliary ground lead). Diode Test (Verifies forward voltage drop and reverse bias functionality)
• 【3-Way Component Activation】Test components without disassembly - the PB100 automotive circuit tester activates them directly to verify functionality, offering 3 ways: in-vehicle, in-hand, and with ground - covering all repair scenarios. power circuit tester kit generates precise activation signals to test lights, fuel pumps, relays, wiper motors, and other critical electrical components. Two LED indicator lights are used to automatically find bad ground contacts. Green light cuts out immediately (circuit breaker trip) indicates a short circuit or overload. Please check the circuit or replace the test point
• 【Voltage & Polarity Tests】In DC Voltage mode, Ancel automotive power circuit probe tester instantly identifies circuit polarity through dual-color LED indicators (red=positive, green=negative) while providing precise 0.1V resolution voltage readings. Boost diagnostic speed by 50% - replaces the traditional two-step process (multimeter + test light) with instant 1-second polarity verification and voltage measurement
• 【Continuity & Signal Circuit Testing】In resistance mode, Ancel circuit tester automotive tool uses the probe tip with chassis ground or the auxiliary ground lead to test continuity of wires, lights, switches, relays, and other components - whether connected to or isolated from the vehicle's electrical system. Switch to AC voltage mode to accurately diagnose sensor signals, capturing frequency and waveform details to check the intermittent faults or signal distortions issues of sensor circuit to verify the accuracy of the DTC
• 【Following & Locating Short Circuits】Ancel car circuit tester features a built-in auto circuit breaker that enables precise short-circuit localization without replacing fuses or stripping insulation. Use the probe tip to activate and energize each of the fuse contacts. The contact which trips the circuit breaker is the shorted circuit. Greatly shorten the time and cost for locating short circuits
• 【Self-Test & Universal Vehicle Coverage】ANCEL electrical system probe tester features a quickly self-test function to verify tool integrity before each use, ensuring reliable diagnostics. Designed for all vehicle types – from compact cars to semi-trucks, RVs, and farm equipment – it delivers seamless trailer light and connections testing with professional accuracy
• 【Complete Kit & Reliable Support】ANCEL electrical system tester kit includes: a diagnostic tool, 20FT main cable + 20FT extension (40FT total reach), 2 replaceable probe tips, dual power adapters (cigarette lighter + battery clamps), and a heavy-duty storage case. Backed by 12-month technical support for any product inquiries
