Transformer secondaries in series backwards

[soligen]

What happens if I wire Transformer secondaries in series backwards?

What I am trying to do is wire 2 secondaries in series so that their voltages add together, but as both ends on each secondary have the same color wire, I have no way to tell the polarity (Phase?) to get the right 2 secondary wires connected to each other.

Does it matter?  I assume it does since the transformer data sheets I look at have polarity markings.

I figure a 50/50 chance of wiring it right.  If I put the secondaries in series properly, the voltage will be the 2 added together, but if I get it wrong, what happens?  I am assuming I'll see a lower voltage, but is it safe? Will it damage the transformer?

One winding is 16V, the other 3V.  16V is just shy of what I need, so 19 will do, with some extra voltage to spare.  I am rectifying this into a DC regulator.

Thanks

It will be ok to connect the windings in series. If you get it wrong you will measure 13V instead of 19V - but no harm done, just reverse one of the windings.

you won't hurt anything.
You will ether get the expected voltage or much less.

Thanks.  guessed right on the first try  .  Now I can do more testing.

Hopefully both windings have the same current range.
If not, then only supply current at the lower limit.
