PowerScan automative circuit tester Autel PS100 is absolutely a must-have tool for every technician or hobbyist looking for a fast and accurate solution to electrical system diagnostics.

Autel PowerScan PS100 Main Feautres:

【2025 Autel New Release Multi-function Power Circuit Probe Kit】Autel PowerScan PS100 is the best Electrical Tester for reducing diagnostic time in all 6- to 30-volt vehicle electrical systems. After a simple hook-up of the tool to the vehicle's battery, you can: ✅Test Voltage & Polarity/ Continuity/Signal Circuit✅Activate Components in Your Hand & in the Vehicle & w/Ground✅Test Trailer Lights and Connections✅Find Bad Ground✅Find Short Circuits✅Red/Green Polarity LED.

【4 Advanced Working Modes】4 advanced modes can be accessed by depressing the Mode Button and cycling through each one: ➊DC voltage: read the DC voltage with a resolution of 0.1 volts. ➋AC voltage: read the Max. voltage, the Min. voltage, frequency, and duty cycle. ➌Resistance: read the resistance between the tip and auxiliary ground lead. ➍Tone On/Off: technicians use the tone in a dark environment to distinguish the test results and turn it off when unnecessary.

【Compnent Activation Function】Autel PS100 Electrical System 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.

【Quickly Identify Polarity & Highly Sensitive Probe】Autel PS100 Automotive Circuit Tester instantly checks component continuity and identifies positive, negative and open circuits. When the positive terminal is connected, the red LED 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. Besides, sharp stainless steel probe for piercing wires effortlessly, also for hard to reach tight areas.

【Overload Protection & Quick Self Test】10 Amp Circuit Breaker built-in to protect the tool from overload. 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 pressed. Besides, Autel PowerScan PS100 Car Circuit Tester has quick self test function, which can ensure the tester is in good condition before use.

【20FT Cable + 20FT Extension Cable】Unlike 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.

【Dual Head Lights & Intuitive LCD Backlit Digital Screen】To be a proper solution for nighttime testing jobs, the Electric Test Pen 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.

1. Two power supply methods

PS100 Circuit tester has TWO power resources. Directly connect the AUTEL PS100 with the cigarette lighter or battery electrode, then you are ready to test. Compared with other circuit testers that only use car battery power, PS100 provides more choices and is more convenient to use.

2. Do More Functions Than Multimeter

Select the diagnostic model by depressing the mode button,and then connect the probe tip to the circuit,the LED is to display DC/AV voltage,resistance.

3.Quickly locates open or short circuit

AUTEL PS100 power probe follows and locates open or short circuit without having to move panels, molding or carpet to expose wires. No more fuses wasting.

What Can Autel PS100 Do?

1. Voltage & Polarity Testing:

While the tool is in DC Voltage mode, contact the probe tip to a POSITIVE circuit, the red LED will light; If contact the probe tip to a NEGATIVE circuit, the green LED will light; If contact the probe tip to an OPEN circuit, neither of the LED will light.

2.Continuity Testing:

While the tool is in Resistance mode, using the probe tip with chassis ground or the auxiliary ground lead, continuity can be tested on wires and components attached or disconnected from the vehicle’s electrical system.

NOTE: You can use the probe tip to pierce the plastic insulation on a wire. This means that you can test the circuit without disconnecting anything.

3.Signal Circuit Testing:

Once you extract a DTC from the vehicle and realize that troubleshooting begins with some kind of sensor circuit, there is a quick test you can perform to verify the code. Testing your sensor is easy while using the tool.

4.Activating Components:

While the tool is in DC Voltage mode, by using the probe tip in connection with the auxiliary ground lead, components can be activated right in your hand, thereby testing their functions, such as activating lights, motors and other on-board electric equipments.

5.Testing Trailer Lights and Connections:

While the tool in DC Voltage mode, clip the auxiliary ground lead to the trailer ground, probe the contacts at the jack and then apply voltage to the probe tip. This lets you check the function and orientation of the connector and trailer lights.

6.Activating Components in The Vehicle:

While the tool in DC Voltage mode, contact the probe tip to the positive terminal of the component, the green LED should light, indicating continuity to ground.

NOTE : When powering up components, you can increase the life of power switch if you first press the switch, then contact the tip to the component. The arcing will take place at the tip instead of the contacts of the switch.

7.Activating Components w/Ground:

While the tool in DC Voltage mode, contact the probe tip to the negative terminal of the component, the red LED should light.

8.Checking for Bad Ground Contacts:

Probe the suspected ground wire or contact with the probe tip. Observe the green LED. Depress the power switch forward then release. If the green LED went out and the red LED came on, this is not a true ground. If the circuit breaker tripped, this circuit is more than likely a good ground.

Note: Keep in mind that high current components such as starter motors will also trip the circuit breaker.

9.Following & Locating Short Circuits:

In most cases, a short circuit will appear as a blown fuse or a tripping of an electrical protection device.Use the probe tip to activate and energize each of the fuse contacts..The contact which trips the circuit breaker is the shorted circuit.

10.Red/Green Polarity LED:

The Red/Green Polarity LED lights up when the probe tip voltage matches the battery voltage within ±0.8 volts. It is added information that could be valuable to the technician.
