Thanks I’m on right track in my head then. On the rotary switch the connection nearest body is a single wire. As is the one at the bottom of the switch as you look in the pics. The rest running along the side are double wires into each terminal. Am I correct in thinking that the connections in pairs are the different tapping points on the coil and could you apply power at one of these pairs with switch out of the circuit, so I can check transformer alone. Thanks.
