Toroid transformer no ouput

[Clive S]

Touching the meter pins together creates beeeeeeep.

Primary:
no beep

Secondary:
red+black = beep
yellow+orange = beep
red+orange | red+yellow | black+yellow | black+orange = no beep

That confirms it the primary is open circuit so see if you can send it back under guarantee.
What you have done is put a dead short across the secondary and burnt the primary out. Next time put a fuse in.
Its called a learning curve so don't get disheartened.
