Nice job on the Insulating common sense cover for the filter. Glad we could help, and your scope like mine helped finalize the job insuring there were no more issues

A bit more information that may help others...
There was a bit of discussion as to how to ground shields and star grounding etc. I do not wish to continue that discussion or further debate on either side of right or wrong, however, I did take a few photos of how I have seen this done on high-end CNC equipment. These photos are from a Japanese built 5 axes CNC machine.
STAR GROUNDING -- often this is explained as a bolt or stud on the side of an electrical cabinet and ALL wires somehow magically stacked up on that single lug. This is the same principle but far more practical and certainly a lot more practical to implement.
As you will quickly recognize in this photo, this machine uses a FANUC control. These cables are servo and encoder cables. Notice the "grounding bar" for the shielding and how the clamps press against the shield. Also of note is how the insulation is cut away in the "middle" of the cable for the grounding and yet allows for the shield to continue to the connector (end) of the cable. I thought that this was very interesting. This style of shield grounding has been used in many different industrial CNC machines over the years that I have been working on.
Just thought that these examples of star grounding and shield grounding could be useful to others.
