Default Re: Kellogg wall phones - need help

Yes connection of the magneto coil to the centre contact makes much more sense than to the normally-closed one that's opened on operation. Well done for working out the error in the drawing.

So one end of the coil (white lead) goes to L2 and one end of the ringer while the other is disconnected at rest but connected (green) to the other end of the ringer and L1, placing it across both the ringer and the line, causing both ringers (local and remote) to operate. The ringer is permanently connected across the line.
