toroid question

Thanks

That my intention was to conect the two windings in serie, i hope was obvious.
And i know for sure witch taps belongs to resp winding.

Now if i understand you right, there can be a magnetic short, if i turn one winding counterconnected?

Only if you parallell both ends - not what you are going to do.

If one winding is reversed both "outer ends" will go the same direction. 0V between outer ends. This is not what you want - you will only get half-wave rectification like this.

When connected right there will be 70V between outer ends which is correct. Nothing will break if one winding is the wrong way - I'd power the transformer without anything attached to secondary and check out which is the correct connection.

Thank you guys

Crystal clear, no further questions.
