The plot thickens...
Do I have one that is wired wrong? Was a change made at some point in production?
I have to admit that the way my Z1000 and Z-controller work make no sense, but having only the one to test I assumed they would all be the same.
Edit: Also, I've taken mine apart and there does not appear to be anything that was fiddled with or changed after the unit was built.
