I have 3 way switch problem.
I needed to extend my switch cables to different location, when cables was removed from switches all cables wasn't labeled, so when putting everything back together I ran into problem.

(See link for picture)

problem is with switch #2 and #4
the switch #2 turns on the light but when the light is on the switch #4 does nothing.
when light is off and switch #4 turns on the light, the light flickers and you can hear buzzing sound at the switch #2.

Please help

@Rus,
Is SW 4 the one that gets extended? Codes would never approve this setup. Also, it could null and void your homeowners insurance. The buzzing is from bleeding amps as switch #2 needs to be a double throw and not a single.
If you insist on this set up use your meter to test continuity through #4 to 1-2 and 3.
The grounds serve no purpose with today's switches and plugs. Remember every foot of wire you lose 2% of your available amps-and every switch you lose 4%. Your meter should isolate the issue.

@Rus,
Sorry about that previous post. It was sent erroneously.

The reason switch 4 cannot turn off the light is because of the black wire coming to switch 2 from cable 2. With that wire connected there is no way for switch 4 to interrupt the power to cable 1 lamp.

Your flickering lamp and buzzing sound is most likely either a loose connection of the red wire on switch 2 or a defective switch 2.
