replaced lights and now they do not work steps to trouble shoot the problem:?

the last light of three was replaced and all worked fine
- Verify that the replacement lights are, in fact, good.
- What is the wiring method? (Is it old enough to have the possibility of switched neutral, Chicago 3way or Carter 3way; or new enough to have a California 3way?)
- What are the symptoms? You are standing at it and exercising it, so what does it do?
- A voltage and continuity tester, along with a hank of insulated wire, are your friends.
everything worked at firstOften a lot of problem solving involves defining the problem,,which can be tricky.
The thread says switches 3 and 4 way trouble shooting..the post says replaced light.
You didnt give enough information to be helpfull.
If you dont mind please start with who s lights they are ,,where are the lights that arent working then on to how the old ones worked and or why they are being replaced.
Yep and I bet you aren't being told everything.all worked fine before homeowner started
:thumbsup:Ahhh...home owner. Open up all the boxes and start over.
how could installing a second light caused the whole system to not work?
And there is no proper color configuration of a three way-four way switch loop, you need to pay attention to logic of what is there, outside of the "Chicago" or "Carter" scheme, you need input and output of the three way loop on common terminals and from a logic (not a physical location) point of view the "traveler" wires hit ever 4 way (being careful to not connect the 4 ways wrong) somewhere between the two three ways.A problem I see often is that you replace a 3-way switch and wire it properly and it turns out it was wired consistently improperly on the other switch. So you have the right wires connected on the switch you put in, but they don't match the improper connections on the other switch.
Like somebody else said, open them all up and start over.
And there is no proper color configuration of a three way-four way switch loop
Exactly, somebody might find it logical to put the two most common colors (black and white) as the travelers with the uncommon color on the uncommon colored screw. Or use the black as the switch leg on the dead-end, Or have a dead-end 3-way with red and white travellers, but the load comes out of the 4-way so they have black and red travelers to the 3-way with the feed.
