Old Doorbell Replacement Wiring

Hi Everyone,
I am replacing an old doorbell and everything I read pointed to it being with two wires and all seemed pretty simple. I took off old ringer and noticed 4 wires in two pairs. Red/Black & Yellow/Blue. I changed these over to the new doorbell but it is not working.
Was thinking maybe needed battery but old bell didnt have one and doorbell doesnt work with power off.
Wiring on old doorbell seems pretty simple
I have tried the new doorbell with wires in both 0 and 1....I also checked on the doorbell button and this has same wires in same pairing at the door. Probably something stupid but any advice appreciated.
Cheers

Ok, I understand now, I thought that was the button. That coil is the striker mechanism for the bell.
So right now you have a disconnect in the circuit where the 9v battery should go. But the thing is that you already have a power supply (the transformer) in the circuit, and you don't want two power supplies.
Check the install guide to see if there is an option to run this bell off an external transformer... or give us the link to the bell and we'll have a look.
What I think you'll need to do is connect junction 3 and 2 together with a jumper.
