  • 2026 Newest Power Circuit Probe Kit Ver 2.0Autel PowerScan PS100 is the best All in one electrical tester for reducing diagnostic time in all 6-30V vehicle electrical systems. SupportTest Voltage&Polarity/Continuity/Signal CircuitActivate Components in Your Hand/in the Vehicle/w/GroundTest Trailer Lights and ConnectionsTracking Short&Open circuitsFind Bad GroundCircuit Breaker Overload ProtectionRed/Green Polarity LED&Voltage Drop20ft+20ft cable. Compared with test lights or multimeters, PS100 provides faster, intuitive diagnosis with extended data display (AC/DC, resistance, diode) while also enables component active testing and short circuit tracing through its circuit breaker.
  • 4 Advanced ModesQuick& Accurate4 modes via Mode Button. Just Contact probe to circuit, LCD instantly displays results: 1DC voltage: read the DC voltage with a resolution of 0.1 volts. 2AC voltage: read the Max. voltage, the Min. voltage, frequency, and duty cycle, shows the modulation from the ECM to an Alternator wire to see if the ecm is commanding the alternator on. 3Resistance: read the resistance between the tip and auxiliary ground lead, you can clearly check fuse/line continuity, pinpoint open circuits & verify switch functions. 4Tone On/Off: it can indicate the tester's on/off status, You can turn it off to avoid ear interference from noise during testing.
  • Compnent Activation FunctionAutel PS100 Electrical Fuse Tester will test the positive, negative, and open circuit easliy, also testing for continuity, diagnosing circuit failures, checking good and bad grounds, easy to read AC/DC current activating components on and off the vehicle, sensing MIN /MAX voltage, etc. By generating activation signals for the components, Autel Circuit Tester Automotive Tool can judge whether the components are in good condition, such as lights, motors, wipers, radiator fans, relays, etc. No jumper wires are required, making the process of diagnosing your car's circuits safer, faster, easier, and less prone to error.
  • Pro Continuity Tester & Signal Circuit TesterPS100 easily locates wire breaks and checks ground quality.1 Resistance Mode: Connect the probe tip and ground lead. A solid connection reads 0.0 with a green LED. OL means an open circuit. You can even pierce insulation to test without disconnecting wires.2 Power Switch Method: Applies voltage to check for ultra-low resistancegreat for ground tests. What to do when faced with reading a DTC to learn that a sensor may have a problem? Signal Test: In AC mode, connect to the sensors signal wire and ground. As you operate the sensor, view live Max/Min voltage, frequency, and duty cycle on the LCD to confirm proper function.
  • Short Circuit Troubleshooting & Built-In Overload ProtectionAs a good relay tester, the PS100s resettable circuit breaker helps quickly locate short circuitsjust apply voltage along the line using its highly sensitive probes to pinpoint the issue, saving both fuses and money! A built-in 10 Amp breaker also protects against overloads, cutting power and sounding a buzzer if limits are exceeded. The circuit breaker will trip if it becomes overloaded to protect the battery and give a buzzer warning. When the circuit breaker is tripped, the Electrical Probe Tester will NOT be able to conduct battery current to the tip even when the power switch is presseduntil it resets.
  • Quickly Identify Polarity & Highly Sensitive ProbeAutel PS100 Automotive Circuit Tester instantly checks component continuity and identifies positive, negative and open circuits. When the positive terminal is connected, the red LED test light is on, accompanied by a beep. When the negative terminal is connected, the green LED is on, along with low pitched tone. If it is an open circuit, the LED light will not light. By using red/green LEDs (illuminated only within 0.8V) alongside the LCD reading, the PS100 provides quick voltage drop detectionturning a simple polarity check into a reliable diagnostic tool. The sharp stainless steel probe easily pierces wires and reaches tight areas.
  • 20FT Extension Cable & Cigarett.e lighter plugConvenientUnlike the power probe, Autel PS100 Automotive Power Circuit Probe Tester comes with 20 feet long cord plus 20 feet extension cord. Combining the feature that it can be powered by the ci*gare.tte li*ghter, and alligator clip for convenient ground connection, you can test electrical circuit system anywhere around the longer vehicles and trailers. Extra cigarette lighter plug, no need to open the hood to connect the battery, so you can easily and quickly conduct in-vehicle circuit testing
  • Dual Head Lights & Intuitive LCD Backlit Digital ScreenTo be a proper solution for nighttime testing jobs, the Electric Test Pen of PS100 Wire Tester comes with a lighting function to support your testing needs in a low-light environment. What's more, this PS100 Circuit Light Tester with highly clear LCD digital backlit display screen, a resolution of 0.1V, clear&visible digital readouts for day and night. Easy to read AVOmeter allows you to read voltage, current and resistance at the fingertip.

  • It's working excellent 👌👍 💯%
It has worked a lot more better then other powerscan testers I've had before and they were a lot more expensive this one proves a special point go by reviews products have not hot expensive they are because only once you try them you'll know money doesn't make it special

  • It' a must have in any Auto Shop!
My favorite thing about the PowerScan PS100 is that it can test both 12v and 24v circuits. Most of the vehicles that I work on are standard passenger vehicles but I may sometimes encounter a few 24v trucks and having this tester keeps the tool kit organized since I don't need various test lamps thus reducing the clutter. Another big plus to this kit is the length of wire that is provided, there has never been a time that I would have to change the location of the wire because it was too short. The cigarette lighter adaptor is a great addon which was supplied and helps me to work smarter and not harder when it comes to interior testing. All in all, it's definitely worth the money. ... show more
