Taz5 owner here, very happy, but had coupling issues recently.
So, I was replacing my couplings and I had to pop off the control box in order to cut off the original because it was loctited. Now that I go to put it back, I find 3 black screws and one silver, and what looks like a ground wire hanging near the back bottom mounting bracket.
My assumption is that the shiny metal screw goes through the ground wire and then into the matching hole (bottom rear) in the control box. Can anyone confirm? I should have taken a photo of the setup before I took it off, but it never occurred to me.
Thanks for any info.
