Why do customers need an automotive circuit tester?
The types and causes of automotive circuit failures are diverse, and the circuit systems are complex. This makes it much more convenient to have an automotive circuit tester to accurately detect and diagnose various wiring faults in the car's wiring, as well as aging wiring and other conditions. Meanwhile, the circuit tester can also detect possible future failures of the automotive circuit systems and provide reliable information for troubleshooting.

Quick Self-Test
Before you test a circuit or component, make sure your tool is in right order by doing a quick self-test.
With the tool is connected, perform a quick self-test. The power switch is a momentary rocker switch located on the tool's body. Flanking the switch are positive and negative
Markings.
Press the Power Switch forward to activate the tip with a positive voltage. The Red LED should light and the LCD display will read the battery voltage. If the sound alert feature is turned on, a high pitched tone will sound. Let go of the power switch and the LED will
turn off and the high tone will cease.
Press the Power Switch rearward to activate the tip with a negative voltage.The Green LED should light and the LCD display will read the “0.0V‟ (ground). If the tone feature is turned on, a low pitched tone will sound. Let go of the power switch and the LED will turn off and the low tone will cease.
Your tool is working correctly and is now ready for use.
Circuit Breaker
IMPORTANT: When powering-up components, you can increase the life of power switch in the tool if you first press the switch, then connect the probe tip to the component. The arcing will take place at the tip instead of the connects of the switch.
The tool is short-circuit protected. Its internal circuit breaker will trip if it becomes over-loaded. The circuit breaker is a valuable test tool as well as a safety measure to protect the tool from overload. When circuit breaker tripped, the LCD will display as below. All other functions of the tool are still active, which means you can still probe a circuit and observe the voltage reading. When the circuit breaker is tripped, the tool will NOT be able to conduct battery current to the tip even when the power switch is pressed. Intentionally tripping the breaker and using the tool to probe can be considered an added precaution against accidental pressing of the power switch.
Work mode and DC voltage
There are four modes to diagnose the electrical system, which can be accessed by
pressing the Mode button and cycling through each one.
While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the DC voltage with a resolution of 0.1 volt.
AC voltage
While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the maximum voltage, the minimum voltage, frequency and duty cycle.
Resistance
While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the resistance between the tip and auxiliary ground lead.
Audio On/ Off
While the tool is in this mode, just do a quick press of the mode button to toggle the audio on or off. While quickly pressing (a quick press and release) the mode button, if a short high beep is heard, this means the audio tone is turned on. If a short low beep is heard, the audio is turned off.
This function is invaluable when working in bright areas where LED illumination alone is not sufficient. The audio feature may be disengaged when desired, such as for applications where the tool will be connected to circuits for long periods of time and the audio could become annoying.
Voltage & Polarity Testing
While the tool is 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 the beep is turned on, a high pitched tone will sound.
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. If the beep is turned on, a low pitched tone will sound.
If connect the probe tip to an OPEN circuit, neither of the LED will light.
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.
When the probe tip is connecting a good ground, the LCD will indicate “0.0Ω ” and green LED will be on. If the tone feature is turned on, a low pitched tone will sound.
Continuity Testing
In other cases, the LCD only indicates the resistance value.
If the resistance value is greater than 200kΩ , the LCD will show “0L”.
There is also another way to prove continuity of connections to ground or battery. Power up the connection using the power switch. If the circuit breaker trips you know that you have a good solid low resistance connection.
NOTE: You can use the probe tip to test the plastic insulation on a wire. This means that you can test the circuit without disconnecting anything.
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.
For example, you suspect there is a problem with your M.A.P. Sensor circuit, then follow the procedure involved with testing this sensor:
Set the tool in AC Voltage mode, using the probe tip with chassis ground or the auxiliary ground lead.Connect vacuum pump to MAP sensor.Contact the probe tip to the MAP sensor positive terminal and observe the LCD
readings which should be a sine wave in normal condition.Apply vacuum.Release vacuum and observe the LCD readings.If the LCD readings are abnormal, there is a problem with the sensor.
Activating Components in Your Hand
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.
Connect the auxiliary ground lead to the negative terminal or ground side of the component being tested. Then contact the probe tip to the positive terminal of the component, the green LED should light, indicating continuity through the component.
While keeping an eye on the green LED, quickly press and release the power switch forward. If the green LED went out and the red LED came on, you may proceed with further activation. Rock the power switch forward and hold it down to provide power to your component.
Activating Components in Your Hand
With the power switch rocked forward, power will flow from the positive lead on the battery into the probe tip, through the tip into the component’s positive terminal, into the component and out of the component, through the auxiliary ground lead and back into the tool, and back to the vehicle battery’s ground.
If the green LED goes off instantly or if the circuit breaker tripped, the tool has been over-loaded. This could happen for the following reasons:The contact you are probing is a direct ground or negative voltage.The component you are testing is short-circuited.The component is a very high current component (i.e., starter motor).If the circuit breaker is tripped, reset it by waiting for it to cool down (15 seconds) and then pressing the reset button.
Testing Trailer Lights and Connections and Activating Components in The Vehicle
While the tool in DC Voltage mode, clip the auxiliary ground lead to the trailer ground, probe the connects 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.
If the circuit breaker tripped, that contact is likely a ground. Reset the circuit breaker by letting it cool down for 15 seconds and pressing the reset button until it clicks into place.
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. While observing the green LED, quickly depress and release the power switch forward. If the green LED went out and the red LED came on, you may proceed with further activation.
Activating Components in The Vehicle
If the green LED went off at that instant or if the circuit breaker tripped, the tool has been over-loaded. This could happen for the following reasons:The contact you are probing is a direct ground.The component you are testing is short-circuited.The component is a very high current component(i.e., starter motor).If the circuit breaker is tripped, reset it by waiting for it to cool down (15 sec.) and then pressing the reset button.
WARNING : Haphazardly applying voltage to certain circuits can cause damage to a vehicle’s electronic components. Therefore, it is strongly advised to use the vehicle manufacturer’s schematic and diagnosing procedure while testing.
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 connects of the switch.
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. While observing the red LED, quickly depress and release the power switch rearward. If the red LED went out and the green LED came on, you may proceed with further activation. If the green LED went off at that instant or if the circuit breaker tripped, the tool has been over-loaded. This could happen for the following reasons:
The contact you are probing is a direct positive voltage.The component you are testing is short-circuited.The component is a very high current component(i.e., starter motor).If the circuit breaker is tripped, reset it by waiting for it to cool down (15 sec.) and then pressing the reset button.WARNING : With this function, if you are connecting a protected circuit, a vehicle’s fuse can be blown or tripped if you apply ground to it.

This tester is exactly what I was looking for without breaking the bank. I must say I was surprised after reading some of the other reviews. Came with all items pictured. The tester itself is straightforward and easy to use. The instructions included are helpful, but could be more detailed in explaining some of the more uncommon functions.I have seen some online videos with the use of tools similar to this. This tester does everything I need it to. It has a lengthy cord to use and you can attach to a 12v battery or a 12v cigarette lighter plug which is useful if using inside the car. It also has a long extension cable to add 20'. Everything seems pretty good quality. I am content with the price. The tip seems solid and pretty sharp to pierce the insulation on some wires. I was worried about the tip not screwing in, but that is not an issue. The included cap goes on first. This does not screw in. The tip then goes into the cap, and screws into the main unit. It screws in securely and didn't have any problems keeping it attached or coming loose. I tested some fuses, grounds and the battery terminals and everything works as expected. The tone on my device is kind of cheap sounding, but does work. The display is intuitive, and displays pretty much the same as in the video for this product. My only wishes were that the included bag was bigger to fit everything it came with. (Everything does fit, but you have to take time to arrange everything to fit correctly. The extension cable takes up the bulk of the room.) The unit itself is lightweight. Everything else has some "heft" to it and feels high quality. The unit itself is plastic and feels hollow. It doesn't weigh much, but doesn't feel cheap either. The rocker switch feels solid and responds with good feedback when pressed. Overall I like this product. I now know it will work for what I need it to. Hopefully this lasts me a long time. For the price compared to similar products, I would choose this model after having tested it out.

This thing works great! At one time, I stored it where it got some water inside, or condensation from the AC, but it would come one, and the screen was blank. I messaged the seller and they immediately sent me a replacement screen out(which is basically the entire inside of the probe, all the electronics). Before it got here, the inside had dried up and started working again, and I haven’t had an issue since I changed where it’s stored. I highly recommend this one, and also recommend the seller! Great customer service!

Let’s face it you’re probably here because you don’t wanna fork out the money for a namebrand power probe I have owned two of these in two different locations where I live and they do everything you need from a circuit tester the display is very nice in my opinion better than a power probe sure it may not come in a case as nice as the PP but that’s besides the point

Had some electrical gremlins to track down in my van & didn't want to put out the extra expense of the power probe. Definitely not same build quality as the power probe but at this price point there has to be some give. Used it to check my ground, check relays & to power on a couple circuits & it did just what I needed. For price can't complain at all, would buy again. My only complaint/concern is that I'd love to buy a new power switch (fuse) to have on hand so I don't have any down time. As far as I can see you can't buy it directly & have to contact the manufacturer & jump a couple hoops to get one.

gave it 4 stars for ease of use only b/c I am not an electrical engineer will take some time to figure out how to use it properly. Tried to find a short in my reverse lights not working will have to consult you tube more than likely other than that the cord is very long does reach all the way to back of my truck.
