Toroid transformer no ouput

[eurikain]

Alright, just got the digital meter. Here is what I measured:

Primary 230V: 0 ohm resistance
Secondaries:
red+black = stable 5 ohms, peeks at 20-40 ohms (probably due the the meter ?)
orange+yellow = stable 5 ohms, peeks at 10-30 ohms (again, most likely due to the meter)
red+orange = 0 ohms
black + yellow = 0 ohms

Verdict ?

EDIT: @Graeme
I had not set up a fuse for the transformer. I only have fuses between the drives and the screw terminals.
