They worked fine. Based on hint 2, it seems they are in parallel. So it is important to replace bad lights promptly. On the other side of the break there won't be the same current. this contact form

Thank you Gary.You are correct about the peak voltage being higher than the RMS and that I should have used that value. Here is one way you could do that. On the 1st section I checked 8 lights before finding the bad one the second was 15 before I found the culprit. 2) the Christmas Light Tester/Repair Gun can test a
The light guys know this. Oh, and just like the lightbulbs in series you can do this with many, many bulbs. Was this answer helpful?

Within each circuit, all the bulbs are wired in series.
Terry found that the Philips LED string contains a small fuse in the plug end. https://www.ifixit.com/Answers/View/1460/Half+of+the+string+of+LED+Christmas+lights+doesn't+light+up. Finally I thought I found the light that had voltage on one side and what seemed like a lower voltage on the other side. How To Fix Christmas Lights Half Out The diodes on these things are balanced with the deign load.

Christmas lights often burn out the moment you unplug them, so the problem often goes unnoticed. But the real solution is to not connect too many strings together. Parallel Christmas Lights
every strand I buy ends up one half doesn't work after a week or two. Some of the caps broke when I pulled them off, usually a part of the sealing ring was left in the socket. But since there is no electric current, the change in potential across each resistor is zero. navigate here Using LEDs is simple.
it was simply a matter of finding the bulb that was no longer in contact, melting the ice( by blowing into the socket while on my ladder to melt it) and How To Shorten Christmas Lights Did this article help you? Wife loves the lights, I love my wife!!
If AC is applied (at suitably reduced voltage--which is obtained by connecting many in series) they only light up during half of the AC cycle. Because the string is made to work AS A WHOLE UNIT with AC power, the observation that flipping the plug should alert you that this function has been destroyed. If you shorten one LED we will have 35 LEDs with total resistance of 11900 and the resulting current will be 9.2ma but not 12.

A different sort of device (e.g., the LIGHTkeeper PRO) puts a tiny high-voltage pulse into the dark string while still connected to the AC line, thus triggering perhaps multiple shunts into A strand of lights that isn't plugged in won't work. They each lit up independently so we strung them up without checking them plugged together. his comment is here When a circuit is working, the hum voltage starts out at 120VAC at one side of the AC line, then declines at 2.4V per bulb until ground is reached on the

I followed the method but it was very misleading with the voltage sensor seeming to beep everywhere.

Your comments are welcome. But that can be deceptive if two bulbs are out at the same time, since at best that will mean "no hum" for the whole substring between them. Something like that would be in the canister, with the resistors. But we may not notice that until much later, and then we will need the marked date.
Was this answer helpful? The bad LED will show different voltages between the wires going to its socket.
For whose without voltage detectors, you can use an oscilloscope set on high gain. They also had a rep contact me and he has provided circuit details for our specific application. There is usually an indicator on the LED holder that shows a "long" side and a "short" side.
The fuses were not the problem.Lynne November 28, 2015 at 11:02 PM Jeffrey R. Leaving the dead bulbs on will cause the other bulbs to burn out sooner. Also, found that the tool often didn't pierce my wire, I would pull trigger several times and it just wouldn't make contact with the copper wire. A short cut is to jam aluminum foil in the socket of the defective bulb; God forbid we would actually change the bulb.
and buy a tube of dielectric grease. When the filament burns out, all the current going through all the bulbs in series stops.

If they weren't sanded enough, that individual bulb would not light.
