First I assume all c2 clocks where the same on the inside. I'm playing with a 65-67 clock.
There is a single connector on the rear which bring in 12V and ground.
The frame is the ground (thus most parts inside) while the 12V is connected directly to the relay coil.
A timing metal lever slowly moves towards the relay, evidently hitting the relay case arm thus grounding it.
Result is that the relay arm pushes that metal timing lever away from the relay, thus starting the timing again.
So confusion is - since the relay is active with the ground connected thru the relay case arm, what opens the circuit so relay
does not fry ?
