Hi,
one connects the secondaries in phase and the other out of phase.

The effect is that it's works or it blows up.
Get it right.
Use a light bulb in the primary feed until you are sure the circuit is working properly.

2 windings on the same transformer will give you 2 sine waves, 50% of time giving current one way 50% of time current the opposite way for each winding.

there is 2 possibilities for placing 2 windings in series:

a connection made so both winding are pushing the same way at the same time and you get twice the voltage.

otherwise 2 windings pushing one against the other and you ge no voltage.
