Product details:

• 【2026 Be.st Automotive Circuit Tester PS100 in Black】Autel PowerScan PS100 circuit probe tester is an indispensable tool for automotive electrical diagnostics and measurement. It supports: Circuit Test, Continuity Test, Component Activation, Ground Test, Locate Shorter, Voltage & Polarity Test, Trailer Lights and Connections Test and etc. No more guess work, you can troubleshoot any electrical issues effortlessly yourself with this 2026 new.est PS100 circuit tester.
• 【Much Affordable & Powerful than PP3/ PP4】Why technicians choose Autel PowerScan PS100 over PP3/ PP4? ✅Simliar Functions (Power/ Ground Testing, Continuity Checking, Voltage Testing, Component Activation) as PP4/ PP3 but only 1/3 the cost. Autel PS100 has more to offer: 👍Simplified Interface & Ease of Use 👍Longer Cable (20ft VS. 40ft) 👍Clear Audible and Visual Feedback 👍Integrated Flashlight and Headlight. Autel PS100 the black version is 2026 New-release and works much more stable than the out-of-date PP3/ PP4.
• 【4 Working Modes】Autel PS100 automotive electrical wire tracer enables 4 working modes to test the electrical systems. In DC Voltage mode, it will read the DC voltage with a resolution of 0.1 volt. In AC voltage, it can read the Max. voltage, the Min. voltage, frequency and duty cycle; In Resistance mode, it reads the resistance between the tip and auxiliary ground lead. In Tone On/Off, you can turn off the annoying noise when the tool will be connected to circuits for a long time.
• 【Activating Component】Autel PowerScan PS100 Circuit Breaker Finder can activate components in vehicle, in hands, and with ground, satisfying all the working scenarios. Autel PS100 circuit tester can generate activation signals to the tested components, such as activating lights, motors fans, wipers and other on-board electric equipment. Autel PS100 also find bad ground contacts, by observing the response of the LED lights, you can tell whether it's true ground easily.
• 【Continuity Tests & Signal Tests】Put the Autel PowerScan PS100 automotive relay tester in Resistance mode, using the probe tip with chassis ground or the auxiliary ground lead, continuity can be tested on wires, switches, relays and diodes attached or disconnected from the vehicle electrical system. Signal Circuit Test can be useful when you extract a DTC from the vehicle and realize the cause might be kind of sensor circuit, testing your sensor and you will find the answer.
• 【Voltage & Polarity Tests】Autel PS100 auto circuit test probe kit provides step-to-step guides to help you easily tell the voltage and polarity. In DC Voltage mode, contact the probe tip to a Positive circuit, the red LED will light and the LCD displays the voltage with a resolution of 0.1V. If contact the probe tip to a Negative circuit, the green LED will light and the LCD displays the voltage with a resolution of 0.1V. And you will hear different beeps when testing on different polarity.
