2026 Autel Powerscan PS100 Power Circuit Probe Tester, 12-24V Automotive Electrical System, Relay, Fuse, Ground Test Tool, Short&Open Circuit Breaker Finder, Component Activator, AC DC, 40FT Cable
Main highlights- 【2026 Professional Automotive Circuit Tester PS100 in Black】: Autel PowerScan PS100 Power Circuit Probe tester enables fast, comprehensive test of all 6-30V electrical systems. This multifunctional power circuit probe tester supports: Voltage & Polarity Test Continuity Test Signal & Circuit Test Component Activation Bad Ground Detection Open&Short-Circuit Location/Protection Circuit Breaker Protection. Equipped with a 160x128 TFT LCD display + 4 working modes + extra 20FT cable +2 power modes +a cigare.t.te lighter plug + built-in light + LED indicator, PS100 can detect without disassembling components—the be.st electrical diagnostic tool for all beginners and professionals.
- 【One-Click Activation of Onboard Components】: The black Autel PowerScan PS100 supports 3 component activation modes: Activating Components In Your Hand, In The Vehicle, W/Ground. You can quickly and accurately judge the component status via signal feedback, no disassembly required—saving time and effort. Examples include activating Motors, Solenoid, Radiator Fans, Fuel Inje.ctors, Windshield Wiper, etc. Ideal for both professional auto sho.ps and DIY enthusiasts. (How: Auxiliary ground to component negative, probe to positive: Green LED = internal continuity. Probe tip to component positive: Green LED = ground continuity. 🔴Probe tip to component negative: Red LED = normal).
- 【4-in-1 Voltage Tester & Battery Tester—B.ett.er than Multimeter】: The Autel PowerScan PS100 electrical circuit tester offers 4 modes to handle full electrical system testing. 1️⃣In DC Voltage mode, PS100 delivers high-precision readings with 0.1V resolution. 2️⃣In AC Voltage mode, it synchronously captures max/min voltage, frequency, and duty cycle(can show the modulation from the ECM to an Alternator wire to see if the ecm is commanding the alternator on).3️⃣In Resistance mode, it directly reads the resistance between the tip and auxiliary ground lead. 4️⃣In Tone On/Off mode, you can freely turn off the sound to avoid ear fatigue during prolonged testing.
- 【Polarity Identification & Continuity Testing】: Autel PS100 Electrical Circuit Finder can display circuit status in real time and enable quick identification of positive poles, negative poles, and open circuits: 🔴 Red LED + high beep = Positive; Green LED + low beep = Negative ; No light/sound = Open circuit. This function prevents ECU damage from reverse polarity! Autel PS100 can quickly test the state of sensors, enabling signal circuit testing and continuity testing. Continuity testing supports two methods:—1️⃣ Resistance measurement (0.0Ω+ LED light= continuity) 2️⃣Power up the connection using the power switch (Circuit breaker trip detection= continuity).
- 【40ft Reach + Built-in Test Light + 2 Power Ways】The Autel Car Circuit Tester comes with a 20ft tool cable and a 20ft extension, allowing access to hard-to-reach areas (e.g., roof-mounted antennas or trailer hitch wiring) and reducing the need for ground searches, Ideal for trailer wiring. The LED headlights illuminate dark engine bays, while the ergonomic grip reduces fatigue during prolonged use. Combining the feature that it can be powered by the cigaret.te lighter（no need to open hood）, and alligator clip for convenient ground connection, you can test electrical circuit system anywhere around the longer vehicles and trailers.
- 【Accurate Short-Circuit Location & Ground Checking& Safety Protection & LED Test Light】: Featuring a high-sensitivity probe, Autel PS100 power circuit probe tester quickly and precisely locates short-circuit points and faulty lines. For ground checks, a green-to-red LED change means bad ground; a tripped breaker likely indicates a good ground (high-current components may also trip it). What’s more, the device has a built-in intelligent circuit breaker protection system: it automatically cuts off the circuit when overload is detected, protecting the testing equipment and extending its service life.
- 【1 Ye.ar & 30 days War.ranty & Te.ch Sup.port 】: Compared to Sn.ap-on’s $300+ testers, this 100% authentic Autel automotive electrical tester delivers identical functionality at 1/3 the cost with a 1-year warr.anty and 30 days no reason retu.rn & repla.cement, b.e.tter than multimeters. Moreover, moving away from the easily faded red version, the PS100 is crafted in a sophisticated black finish that resists dirt and workshop grime, ensuring it stays looking new with minimal upkeep.
