Greetings, my doorbell chime is ancient but my parents seem to love it. It doesn’t have a “trans” terminal and instead has front, side, rear, terminal a, and terminal b. I currently have wires connected to terminal a and b, also the front and rear terminals have wires connected (I have two doorbells) and the side terminal isn’t connected. I’ve attached a picture of the chime board.
I currently have the video doorbell 2 and tried installing the pro. I connected the power kit between front and side (as instructed by Ring support). The doorbell powered on but my chime kept ringing continuously. I then yanked the wires from the front and rear terminals to make the chime stop. I then reverted back to the old video doorbell 2 and reconnected the front and rear terminal wires. The doorbell didn’t power on but the chime still kept ringing. I then tried switching the front and rear wires, but the rear chime now keeps ringing. My question is: is there a short somewhere? Or did I blow up the transformer?
What can I do to at least get the doorbell powered up again?
Any help with this would be much appreciated.
