I have bought a variac and have wired it up as per instructions given but I'm only getting 90v output wherever the wiper is. Clearly I've wired it up wrong, but I can't see how. Can someone point out what I'm missing please. Thank you.
I was instructed power comes in at the top and out at the bottom, but looking at the cover i'm not so sure this is correct.
