I have some knob and tube wiring I learned is active. I'm trying to determine what knob &amp; tube is still "alive", or not. Can this be used for that?

It can help with this task. If this tester glows when touched to any of the wiring in your house, that wire is very likely to be active and energized. If it doesnt glow it means that wire is de-energized. It could be de-energized because it has been disconnected and abandoned or it could be de-energized because there is a switch or circuit breaker or sensor ahead of that wire that is currently in the off position. One last thing is that you need to be able to differentiate between the "hot" and "neutral" wires. This can be more difficult with old knob and tube wiring because they aren't always colored differently. The reason this is important is because the neutral wire will often not make this tester glow, even when it is part of an active circuit. That is because a neutral wire that does not have electrons flowing through it (as in it is not currently feeding a light bulb or anything else with power), does not have a voltage present. If this is confusing I would highly recommend consulting an electrician.

While I would have to destroy my own cable to really find out, I'm reasonably sure it is probably a stranded copper wire. I can't imagine it would be otherwise but I'm not 100% positive.

Sorry for the delay, camping for the last week with no service of any kind, it was great! I use copper wire ends sized for the studs on the back of the switch, soldered is the best way to go, but if you have a good crimp tool you should get a lasting connection. Coat the connections with a good dielectric grease to help prevent corrosion.

O.k. Thanks! I'll try that tonight. I saw that short knob and I keep messing with it, but nothing is happening. I think I'm not doing it right though so I'll try again and maybe get someone to help me. When I jiggle and pull the knobit, do I pull on the base of the machine at the same time? Just making sure I understand what to do here. Thanks again!

Just my opinion, and I am not an expert, but I would guess it would be pretty dangerous to do that, especially if you think there's any chance the circuitry is damaged. If it was a defect, I would contact the manufacturer, but if you made attempts to modify it, you're probably on your own and should buy a new one.

Hi Patrick no, the unit is more for replacement i used my existing wiring and air tube. hope this helps ?

Good day, I purchased some of this model LED tube from this particular company and the tubes work well. Realize that LED fixtures are NOT compatible with fluorescent ballasts, so you cannot plug them directly into a pre-existing fixture. The ballast must be removed or you may "hot wire" them around the ballast. Different manufacturers wire differently. There are four prongs: two on each end. You only need two of those prongs. Either the two on one end or the same two on opposite ends. I am currently on the road, so I cannot look at this particular tube to tell you how to wire it, but if you say you have "hot-wired" and it works, you have picked the correct wiring configuration. Yes, it is wired directly, no ballast. That's the way LEDs work. Hopefully this message has been some help or, at least, reassures you. Good luck. Bob

You would need to make sure you're able to use your amps power section alone. You can find out by looking at the back of the amp/head itself. Otherwise you could try running it through the amps clean channel.

no, the coil probably burned out. It is not designed to be on continually. I use mine for an air horn and it works fine for that but if you are wanting something that stays energized for a long time it would be better to use a higher voltage and less amps

Yes. I guess there is still ghost current on some circuits. Had to pull them out of a ceiling fan due to this. Haven't tried them anywhere else yet.

Is the battery dead? I had one of these amps suddenly stop working for me after about a year of use, I think the wiring goes goes out eventually. You may want to try returning it.

This has never happened to me. I just checked the knobs and they work as they should. Hope this helps. Thanks, Brigida

Honestly I'm mot sure. I did take apart the switch unit to see if there were posts to change the frequency. When I opened it I noticed the main board was a very cheaply made one materials wise. I would wager the seller intends low amp and voltage for the unit. Im not an electrician but I do know computers. Im basing my guess on personal observations.

Neil Snyder's answer above mine is correct. I suggest making a test run on a known wire to see how the instrument responds when you move away from it laterally, and when you reach the wire's end or simulated break.

Not sure what you mean here. it is probably a faulty switch. If you want to try to take it apart, there might be some wiring problems. If you're not down to take it apart and look at it, there's really no way to fix it.

Yes, in some cases you can detect the wiring, but I have not found it to be 100% reliable.

Most likely yes. First use a multimeter to check if the hot wire (black or red where I live) is live. if it is not, Use the alligator clips on the neutral (white) and hot wires. As Malloy said below, make sure the breaker is off, even if the hot wire is not live. Better safe than sorry
