Getting comfortable
Ok will try, no resistor was in the box, but a replacement arrives tomorrow.
Should the chime have the connections bridged this way? #0 and #3 have that thin wire bridging them.
Could I damage the doorbell messing about with it like this?
That wire is part of the circuit from the factory, leave it in. It completes the circuit when using instructions #3.
You could damage the doorbell if you hooked up the transformer directly to it.
