Installing triplex doorbell, one 4wire wire, help with wiring??
Can someone please help=85 I am trying to replace a doorbell in a triplex I live in. Three separate bells, three separate buttons.
There is one 4wire wire (red, green, yellow, black) coming out of the wall to the door bell.
Doorbell 1 Screw 1: Red Screw 2: Green
Doorbell 2 Screw 1: Red, Red Screw 2: Black, Yellow
Doorbell 3 ??? (Doesn't work) Screw 1: Red Screw 2: ???? Nothing ???? Doorbell 3 is the problem. When I looked at the doorbell, it appeared that only one red wire was attached to one of the screws. The other screw didn't have any wire attached. I could be wrong, but the red wire on Screw 1 looked like it was one of the red wires from doorbell2 on screw 1??? It came loose when I was uninstalling it, so I don't know. For that matter, it is possible that a wire on screw 2 fell behind the wall somehow? I really don't know=85.
Other information: There is a twist on wire connector (marrette) for the red wire. Currently there is just one red wire coming out of the marrette, but that doesn't make sense to me. I have to assume that the marrette was used to split a red, but I can't see it. I suppose someone could have just been trying to lengthen the red wire, but that explanation seems somewhat implausible?
Can anyone who understands electricity or doorbells tell me how door bell 3 should be connected? Thank you!!
