Ultimate Wiring Circuit Tester Kit Demonstration


You can see the kit comes with three parts to it, obviously the tester itself here, the alligator clip that will actually go on to the end here. You also have the hook that goes over the end which goes around and pierces the wire to test it. This is the larger alligator clip you use for the ground. The way this unit identifies the circuits is done in two different ways, it lights up and makes a sound. We'll demonstrate that with this light we have hooked up to a power supply. This is the ground so this will go to the ground of one of the lights you are working with. This probe here will go to the light itself. We'll use our hook here, and we'll just test the wire. Just squeeze it gently and you hear a tone and it lights up. What's also nice about this if you actually reverse the polarity of this, it will reverse the ends and tell you the polarity.

We'll use the small alligator clip here. We'll attach it to our ground here and our original ground to the power supply here. You can see it just lights up, so that tells you that would be the ground and this the power wire. It helps determine the polarity if you're not sure which end of the circuit you're on. You can see this is a nice heavy duty unit, these are the ones we use in our own shops, and that's what you have for part # 40376.
