Wanted to change my door chime with chime from former home. Purchased a larger transformer as directed. The tranformer has 3 connector screws. Hooked one to transformer screw and the other to the front door bell screw. Connected the white wires all together with a twist cover. The followed that same technique to the black and copper ground wires. Door chime does not work. There is another wire with 4 thinner wires in one. How do they connect with the above scenario of wires?:confused:
