We continued investiagation about not responding coil of the input mirror. (See entry #1742)

We measured the resistance across each coil loop at the flange. For all the working coils it was about 2.4 Ohm for the not working one we found the loop is open.

This suggests the magnet coud be fine and the problem could come from the coil circuit.
