Polarity test and continuity test

Polarity test:

This tool can test the uncertain polarity of contacts in the vehicle circuit. This tool can test the uncertain polarity of contacts in the vehicle circuit. Unfold the wire. Connect the red clip to the positive terminal of the car battery. Connect the black clip to the negative terminal of the car battery. Touch the tip of the probe to the positive (+), and the LED should light up red. Touch the probe tip to the negative (-), the LED should light up green.

Continuity test

Expand the leader. Connect the red clip to the positive terminal of the vehicle battery. Connect the black clip to the negative terminal of the vehicle battery. Connect the auxiliary ground wire to one side of the wire under test, and connect the probe tip to the other side. When there is continuity, the LED will light up green. If the LED does not light up, there is no continuity.

Test the components outside the vehicle electrical system and test the components in the vehicle electrical system

Test the components outside the vehicle's electrical system

Expand the leader. Connect the red clip to the positive terminal of the vehicle battery. Connect the black cip to the negative terminal of the vehicle battery. Connect the auxiliary ground to the negative terminal of the component under test. Press the button (the side where the LED is lit red to touch the probe tip to the positive pole of the component under test to activate the component. If the LED turns green and the buzzer sounds, please stop the test and check whether the component is defective or the component’s The rated current is higher than this tester.

Test components in the vehicle's electrical system

Expand the leader. Connect the red clip to the positive terminal of the vehicle battery. Dip black into the negative terminal of the vehicle battery. When the S control switch of the element is on the positive side of the element, press the button to the "-" side, and the LED will light up in red. Touch the probe tip to the positive terminal of the assembly. The component will be activated.

Jumper operation

When the negative terminal of some components needs to be well grounded for large current to flow, this tester is a good tool for testing its grounding. Expand the leader. Connect the red clip to the positive pole! Car battery. Connect the black clip to the negative terminal of the vehicle battery. Press the button to the side, the LED should light red and provide positive voltage. Then let the probe touch the negative terminal of the element as quickly as possible, the LED indicator turns green, and the power indicator lights up. vri meaus itiswelded. If not teLED Remaining

Short circuit tracking and positioning

Short circuit tracking and positioning

Expand the leader. Connect the red cip to the positive terminal of the vehicle battery. Connect the black clip to the negative terminal of the vehicle battery. Press the button to the'"-" side, the LED should light up red and provide a positive voltage. Remove the blown fuse from the fuse box and start tracking from the two terminals of the fuse socket. Use the probe tip to quickly touch the wire. If the LED lights up green and is accompanied by a buzzer, there is a short circuit or an overload component on this side. Please pay attention to the color or identification code of this wire. Follow the wire as much as possible along the wire harness. Locate the color-coded wire in the harness and expose it. Cut the wire. Follow the wire in the direction of the short circuit and repeat his process until you find the short circuit. If there is a separate check if the components are good.

As a professional auto mechanic I utilize electrical diagnostic and testing tools on a regular basis. This circuit tester allows for not only testing for the presence of voltage and ground with a simple touch of the probe tip and looking for either a green or red led light, but also allows the user to apply both voltage and ground to the circuit or component being tested to verify operation. Super easy to use and amazingly useful !!!!

Auto electrics is what I used this for. If you overload the tool it melts the circuit board. Other than that it works well. Like an inexpensive power probe.

Great tool for assistance in troubleshooting power or ground in 12 volt systems. Small size with long + and - cables for battery connection. Long piercing probe for tough to get to wires or even pin holes on harnesses. Great price for this type of tool.

Got this for obvious reasons and it does the job very well. I was able to diagnose and find a loose wire on my motorcycle, causing the Neutral to go on and off. It is well made and works great. I would purchase again.

This is supposed to have a circuit breaker in it so that if you apply positive or negative to the tip and it's a short, the breaker will pop. As far as I can tell, it does have a breaker, but it's very very not sensitive and you can't hear it pop or reset. I'd much prefer a breaker exposed on the outside so you can see it pop and reset it when you want.I tested this with a weak battery and it definitely works to show green and red based on what the tip is touching - that's nice. Applying positive to the negative terminal or negative to the positive generates a very weak buzzer after several seconds and the unit gets very warm I tested with a volt meter across the terminals and it definitely is giving up after some time (i.e. the breaker popping) but I can't hear it pop or reset. The fact that the body of the unit is made of super cheap plastic and gets very warm makes me think you better not be depending on the "safety" features of this thing.Regardless, it does mostly work and it's cheap. You get what you pay for I guess. If you just need this for occasional troubleshooting and you know what you're doing, it's probably fine. If you don't know what you're doing, you should probably get a more expensive unit with more reliable safety features.
