Installing triplex doorbell, one 4wire wire, help with wiring??

Can someone please help… 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….

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!!

Try:

Doorbell 1
Screw 1: Red
Screw 2: Green

Doorbell 2
Screw 1: Red
Screw 2: Black

Doorbell 3
Screw 1: Red
Screw 2: Yellow

Looks to me like Red is common, and green, black and yellow are the
three door bells.

Hi, thanks for the response. Curious though...why is the yellow and
black tied together on the same pole (with red on the other) for
button #2?? The system was working this way before?
Cheers,
Rob

Uh, maybe someone installing it screwed up? OK, what are the make, and
model of the system?
