I recently had some old knob and tube wiring replaced. I haven't finished patching the walls yet and there is one location with new wires where, when I get this pen about 6-8 inches away, it lights up red like crazy. I'm worried this is indicating something is wrong with the wiring. Any thoughts?

There is a hot wire under there somewhere.

My ceiling fan is not working, probably burned out. So, I buy this and put it up against the wires and it will tell me if power is still running to the unit, correct? This will tell me if the fan is no good, or if there is not power running to it, right?
Asked by: mud
Correct! I used this to detect which wire was out when I changed my GFI.

Work with testing voltage to outside AC unit? I need to replace my capacitor, would I just touch this to all terminals?

Asked by: Josbryhar
Hi Josbryhar! Definately this is a good tool to make a guesstimate if the AC unit has power going to it. I always test at the line terminals with a meter. Once I know the unit is locked out I ground off any CAP I am working on with an insulated screwdriver to ground. Caps can hold an electrical charge. My meter has a scale on it for microfarads with which I can see if it the value matches the label on the CAP. Got one from H D. Others there. Klein Tools 600 Amp AC/DC True RMS Auto-Ranging Digital Clamp Meter. Follow meter directions. Best of Luck!

We live in an older house and a lot of the wires are not labeled or mislabeled or just plain weird... With this tester it is super easy to touch a wire or an outlet and know if you have power and which line is hot. It also helps to make sure you have turned off the right breaker when doing work or repairs. It even turns itself off after it hasn't been in use for a few minutes.

This little tester is invaluable! this is easiest and best way to check if a wire is positive or not. No wires, no fuss, just turn it on and point. I own 4, one on my tool belt, one in my toolbox, one in my car and one in my truck. I highly recommend this tool. It's easy, reliable and in my book a life saver!

It worked as expected. In retrospect, I should have purchased the more expensive model. It's range goes down to 12 volts AC, which be useful when checking outdoor accent lighting and sprinkles wiring.

Rated 5 out of 5 by from Very good tool It tells me the power line in a very easy and simple way. It flash's and beeps when the line has power. It is very good for safety. I do not need to use other complex tool, like ohmmeter, to check the power.

Absolutely flawless, hands down one of the best purchases I've made in a long time.  I can't speak highly enough about this product, which is solidly built and perfectly designed.  It has become a staple of my homeowners tool kit.  I've used it at my house, several friends houses, and my wife's business during electrical renovations across a wide variety of DIY projects.  This unit has helped me run wiring, map circuits, rewire rooms, install sockets and plugs and switches.  It's a constant companion and I love it.  It works peerlessly sounding both an audible and visual alarm when current is detected.  It's so easy to decipher, my wife has used it to help me map the wiring in my new house since the diagram on the panel was completely inaccurate.

Rated 1 out of 5 by from Not sensitive enougj I tried out this tester because i was unhappy with thr inconsistencies with the most popular version of this type of voltage tester. This one is no better, in fact its worse. To make a product such as this, with so mucj safety liability at stake, you would think the product would be very sensitive to any AC volltage. You have to hold this tester at the right angle, multiple times in order for it to light up. If i have to assume all wires are hot, or get out my voltmeter, then this tool is worthless.
