Product Description

There is one continuity tester included in the set.
A SHARP STEEL PROBE can penetrate through insulation and reach into tight areas.
With the 54" cord you can extend your testing range, test flexibility, and enjoy greater freedom.
In the handle, there is a light bulb that indicates when the circuit is working properly.
The voltage regulator, fuse, switch, broken wire, mechanics, electrician, and more can benefit from it.

Questions & Answers

Which is the best way to use this? To test car fuses without having to remove them, I am looking for something that fits in a glovebox. Can you tell me what I should connect the black end of the tool to?

You can locate it anywhere on the ground. An example of a ground location would be any bolt passing through the frame. In terms of firewall, it is a negative charge area on the ground.

What is the address of the place where I can purchase replacement bulbs - the bulb in mine has gone out. ?

Bulbs like these are frequently used in older vehicles for dome lights on the roof of the vehicle. If you need to replace it, you can bring the old one to an auto parts store or another outlet that sells automotive parts.

If I need a new bulb, where do I get one?

If you are searching for a 12v miniature bulb, visit your local hardware store or auto parts store.

LED test lights can't do what this one does
5/5

In addition to the length, gauge, and material of the cord, and its overall ruggedness, I was impressed with Using this method, you can check the spark between the plug wire and the ignition module by seeing how far the spark jumps, as you can visually see both brightness and distance, which you can't do with an LED It's the best device for checking fuses in no time. Just connect the clip to GND, then look at the fuses and you will find a little tiny bump above each pin. Touch the bump with the ultra sharp point and see if the light comes on. Go to the end of the line if you want to check a blown fuse as this is the fastest way. I checked 20 fuses in under a minute. I have dropped it and banged it multiple times, and it continues to work. I agree that there are valid complaints about the crimping and soldering, however, it was delivered for 10$, so how difficult is it to fix the crimp or add a little with the metal tip, this is a weapon intended for home defense, the metal is hard and hard, and the razor-sharp tip will slice deep into a finger or go past you in an accident. While I have a large collection of knives and guns, I ground the tips down for safety reasons. You should be able to easily put it right through the hood or door/fenders of The switch can be used to ground other light bulbs or coils, this can work just like a switch all the time and leds have a hard time.

The light is very bright
5/5

This can be used if the battery in an old automobile is draining. Taking away the ground and connecting it to the battery is the best way to do this. This now lights up if something is drawing power. If anything is running, remove the fuses until the light that is sensitive stops shining.

We are only running a live test and not a continuity tester
3/5

The tester is only a live circuit tester, not a continuity According to the description, it is "self-driven" In a continuous circuit, you put a battery in the wire, and if you have a clip attached to the wire by the probe and it sees current, the light will come on. ) My curiosity has always been why voltage and current testers aren't included in the same product, so I thought that this was the answer. This voltage tester is well made and of high quality, it is just misrepresented as such.

Testing is done well by this individual! A couple of things about this tester it works I was surprised by how well it turned out
5/5

When used to check continuity, as well as to locate shorts in a wiring circuit, it is very helpful. The tool can be used to troubleshoot problems and to add to an existing circuit or build a wiring harness to implement easy connections. The sharpened tip can easily penetrate the wire covering when needed. It is also useful for backing up wires Find a connector by probing it. In addition, the quality is far superior to what had been There is plenty of wire cable and an alligator clip for durability, as well as a see-through window There is a nice thick handle on the through section. There's even a good strain in this one - An internal relief spring is attached at the back end of the handle, where the wire cable exits. As I see it, it reminds me of tools manufactured fifty years ago when companies expected their products to last That would be a very good surprise if it was from China!.

I needed it to do exactly what I needed it to do
5/5

A recent purchase for my motorcycle was an auxiliary light kit. A power connection going to the tail light is switched in order to prevent battery drain. The voltage tester I used can be found already attached to the wiring block going to the tail light. By probing the female connector sockets for the wire and confirming by turning on/off the lights, I found the wire within seconds. The perfect translation.

I needed it for what I needed it for
5/5

During the process of hard wiring a radar detector to my truck, I needed a means of determining the source of the positive signal. What I wanted was exactly what you provided. For a voltage meter, I did not need to pay an arm and a leg. There is no doubt I will use this a couple times, but for the purpose I would use it, it will be more than adequate. A simple test is to attach a clip to a ground source, and then to touch the probe to the terminal end of the wire. If the light in the handle illuminates, then the wire is a positive source, otherwise it goes to the next wire. In terms of durability, I didn't rate it because I have only used it once. I am not sure.

The only complaint I have is that the neg cable jaws are difficult to open and do not Using the wire stripper, I removed the ends of a piece of wire
4/5

One jaw should be wrapped around a ground underneath, while the other is used for the jaws. Although I read reviews where people complained about the light, I found it to be bright enough. Have you ever used an older.

This is a good one to buy
5/5

It seems to work well. It has a long cord and everything appears to be attached the way it should. Although the pictures show a bright light, the light is nowhere near as bright as what appears. This is not true at all. This tool starts operating at a certain voltage when the light bulb is plugged in. In addition, the photos appear to suggest that the power cord can be detached? Not at all.
