Ok so I'm doing this baby steps.
I got a dual primary & dual secondary transformer. Input is 120v, output 22v.
The input wires are red & black. There are 2 sets. I have isolated each set.
I have my AC coming in from the wall outlet, to a fuse holder. From the fuse holder to the transformer primary.
When I wire up 1 primary coil, I get 22v on either of the secondaries. If I try to parallel the 2nd primary coil (which I've gathered is what I'm supposed to do), as soon as I plug it in or throw the power switch I get a blown fuse.
I'm wiring the two reds together and the two blacks together. I'm on 120v mains.
Do I need to reverse one of the primary coil's polarity? In other words, connect the red of coil A with the black of coil B, etc.?
Or is it normal to blow a 1A fuse with a big (500va) transformer? I have nothing connected to the secondaries yet.
I'm beginning to think there's something wrong with my transformer. I've tried wiring the primaries up every way possible. It always blows a fuse.
