No. Just the one you you could not read on the bridge.

 And,  if there were shorts,  I'd expect to get some kind of reading.

The inductance could be near zero. I don't know.

The reason for the higher current test is if there are huge AC losses, you
might not get a reading at low currents. It's quick and easy to do.

Good luck. Keep us posted.
