Mmm. It doesn't work.... 
I don't know if I've wired the power transformer incorrectly, or if it is duff.
I've attached a pic and wonder if you could give me your thoughts?
I have the incoming mains neutral connected to the SCN pin and the incoming mains live (via an spst switch and fuse) to the 250V pin. No connection to the 0V pin on this side. I have the circuit of the ratio meter fed from the transformer side marked OUTPUT. The thing is I have continuity on the output side pins, but only on the input side pins between 0V and 250V. There is no continuity between the SCN and 250V pins and also not SCN and 0V pins.
This is the first time I have wired a power transformer so have no experience to draw upon. I am assuming therefore that I either should have wired the incoming mains neutral to the 0V pin rather than the SCN pin, or that the transformer is dud. Any thoughts?
Thanks
Nick
