Transformer Question: Dual Primaries and Secondaries

[kurtlives]

Got a transformer like this...dual primaries and secondaries

120V
0V
120V
0V
12V
0V
12V
0V

I would like a 120V primary and a 24V secondary...
For the primary I would hook the two 120V together and the two 0V together then to the 120V wall socket.

How would I get 24V on the secondary though?

Thanks...Chris

I'm assuming that the primary is
120
0
120
0

And the secondary is
12
0
12
0

To get 24V output connect the bottom 12V to the top 0V. The 24 output will be the bottom 0V and top 12V. Check with you multimeter that you get 24V output before you hook it up to anything to make sure the phase of the secondaries is as marked.

12 ------ output

0  ---|
        |
12---|

0 --------- output
