Are you wanting to know the best way to trouble shoot and fix these.....
What you do is go to your local home improvement store and purchase a non contact tester, or some call them stick testers - and even at Christmas time they refer to them as Christmas lights tester. It will cost about $10. Then what you do is plug in the lights, then start at the beginning of the string and place the tip next to each bulb. If it beeps its a good bulb. If it does not beep, that is your bad bulb. Replace it and you should be good to go. If not keep repeating this process until the lights come on.
these aren't mini lights
do those testers work with "old school" C7 bulbs with E12 bases?
and even though the system is a parallel circuit and there's current from the male end to the female end (I plugged in a trouble light) a bad bulb could still be causing the problem?
If they operate on 120v this tester will work just fine.
okay and I'll find a bad bulb and that will fix it?
That will help you find the bad bulb - then you can fix it.....
okay I'll give it a shot. so it's not likely that the string itself needs to be replaced (recognizing that there are no guarantees)
Im sure its just going to be one or two bulbs... .happens all the time.
cool thanks very much!
