• 【2026 Upgraded Autel PowerScan PS100 All-in-One Circuit Tester】Autel PS100 is a professional automotive electrical diagnostic tool combining circuit tester, test light, continuity tester, short circuit finder, relay/ component activator, and voltage tester in one. It performs Circuit, Continuity, Ground, AC/DC Voltage & Polarity, Relay, Component Activation, Trailer Light, and Short Circuit Tests to quickly locate wiring faults, bad grounds, blown fuses, and open circuits. Ideal for both professional mechanics and home DIYers to diagnose vehicle electrical problems faster with confidence.
• 【More Affordable Than PP3/PP4, More Features for Less】 Why choose the Autel PowerScan PS100? It delivers the same core functions as PP3/PP4—including Power & Ground Testing, Voltage Testing, Continuity Testing, and Component Activation—at about one-third the cost. Plus, PS100 offers a 40 ft cable (vs. 20 ft), an intuitive interface, clear audible and visual test indicators, and a built-in LED flashlight for working in low-light areas. The 2026 upgraded black edition provides faster, more stable, and more user-friendly electrical diagnostics for professional technicians and DIY mechanics alike.
• 【4 Test Modes for Quick Electrical Diagnostics】Autel PS100 features 4 dedicated diagnostic modes for fast, accurate electrical testing. DC Voltage Mode measures voltage with 0.1V resolution; AC Voltage Mode displays maximum/minimum voltage, frequency, and duty cycle; Resistance Mode accurately measures resistance between the probe tip and ground lead; Tone On/Off Mode lets you mute the audible alert for quieter operation during extended testing. Switch between modes instantly to diagnose sensors, circuits, wiring, relays, and electrical components with greater speed and precision.
• 【Power & Ground Component Activation】Autel PS100 safely applies Power or Ground to activate and verify automotive electrical components before replacement. Instantly test lights, cooling fans, motors, relays, wipers, fuel pumps, solenoids, and other 12V/24V electrical devices to confirm proper operation. It also detects bad ground connections using clear LED indicators, helping you quickly identify faulty grounds, wiring issues, and electrical failures—reducing diagnostic time and eliminating unnecessary parts replacement.
• 【Continuity & Signal Circuit Testing】Switch the Autel Power Scan PS100 to Resistance Mode to quickly perform continuity tests on wires, switches, relays, fuses, diodes, and connectors—whether installed on the vehicle or removed. It also supports signal circuit diagnostics, helping verify sensor circuits and electrical signals after retrieving DTCs. Quickly pinpoint open circuits, damaged wiring, faulty connections, and sensor-related issues for faster, more accurate troubleshooting and repairs.
• 【Fast Voltage & Polarity Testing】Autel PS100 car relay tester quickly identifies DC voltage and circuit polarity with intuitive LED, LCD, and audible indicators. Touch the probe to a positive circuit to illuminate the red LED, or a negative circuit to light the green LED, while the LCD displays voltage with 0.1V resolution. Distinct audible tones provide instant polarity confirmation, allowing technicians to accurately test batteries, fuses, relays, connectors, switches, and wiring for faster, error-free electrical diagnostics.
• 【Quickly Locate Short Circuits & Bad Grounds】Autel Power Scan PS100 helps you trace and locate short circuits without repeatedly replacing blown fuses. Simply energize fuse circuits to quickly identify the circuit that trips the breaker, making fault isolation faster and more efficient. It also instantly detects bad ground connections, helping pinpoint wiring faults, shorts, and grounding issues in lighting, power, and electrical systems—saving valuable diagnostic time for both professional technicians and DIY users.
• 【40FT Cable, Durable Professional Design】Autel PS100 automotive circuit tester includes a 20ft main cable plus a 20ft extension cable, providing a total 40ft reach to test electrical circuits anywhere on cars, trucks, SUVs, RVs, and trailers without moving the battery connection. Built with a stainless steel probe, bright LED work light, easy-to-read LCD display, and rugged carrying case, it supports dual power options via the vehicle battery or cigarette lighter adapter for maximum convenience. Engineered for long-lasting durability and reliable performance in professional workshops and home garages.
• 【Universal for All Automotive, 100% Worry-F.ree Purchase】Autel PS100 electric circuit test kit can work on all 6-30V cars, boats, trailers, ATV, motor homes and other vehicles and machinery to measure wiring, fuses, relays, battery, ground connections, fuel pumps, ECM sensors etc. Autel electric tester is backed by 1 year qua.lity war.ranty, 30 days full re.fund/ new re.placement.
