Toroid transformer no ouput

[eurikain]

What do you mean by "no resistance" and "high resistance" ? I would expect to see less than 10 ohms between the Blue and Brown on the primary. I would also expect to see less than 3 ohms between the Red and Black as well as the Yellow and Orange. Can you let us know the actual values you are seeing.

I happen to have a meter that does not have a digital display but just an indicator. I will go borrow my friend's ohmmeter to have better readings this afternoon.

The meter sends 1000 ohms, so if the measured resistance is supposed to be 3 ohms, it is nearly impossible to see the indicator move. But fr the "high" voltage, I see it easily as the indicator goes to the maximum value. Do you understand what I mean ?
