also continuity between all grounds

Yes it's a misprint of 240V in the specs.
There isn't even a switch for it.
The old Durostar had the 240V switch and that was one of the reasons I wanted the EMS in case the switch was accidently turned on

This makes even less sense. Of course when I say "continuity" I'm assuming an ohm meter that's reading near 0 ohms, not a handful or more through a coil. I should have been more clear.

Also, without your bonding plug in there, the grounds should connect to nothing but each other and the ground lug.
