I am looking for any information on how indoor Christmas light sets
work. I would like info about amperage, wiring, why strands of lights
don't work anymore, replacing bulbs, splicing broken cords, types of
lights, etc. I am trying to repair a string of lights by using
electrical tape and splicing. |

-They are wired in series, and the newer ones have a fuse in the plug
a 100 light string may have two sections, with 50 2V bulbs each.
Some of the bulbs have shorting clips that allow the string to run with
a bad bulb (at higher voltage, and less bulb life!) and some just
go dark when any bulb dies. Older sets, or ones that use a screw-in lamp are usually wired in
paralell, with each bulb being 110V. - throw it away! It isn't worth the time and effort especially
if you are a novice and need instructions. The risks are too great if you
should do something incorrectly resulting in a shock or fire hazard. -First check to see if there is a fuse in the AC plug. There are
several types. some push in between the prongs while others are
under a screwed on cover of some sort. I the fuse is good 99.9 %
of the time the problem is a bulb. If you shake the bad string
and the light it is usually a loose bulb. Otherwise the bulbs are
designed to close a switch when they burn out. Many times the
switch doesn't make and the whole string goes out. Here's were
the bulb changing comes in. Swap bulbs one at a time from the bad
string into a good string. If the bulb doesn't light, but the
good string comes on, that bulb has burned out and closed the
switch. |
