I have the little dimmer circuit from Van's on my cockpit LED lights. Tonight, they wouldn't dim and I knew that one of the wires had come out of the cheesy little screw connectors. Easy fix, but while doing it, I realized I had the "optional ground" wire from the instructions installed, but didn't need it for it to work.
So...what is it there for? Reinserted the other wire from the pot and tightened it down, working fine.
What's the purpose of the optional ground wire??? If it's unnecessary, I'll crawl up underneath the panel during annual and remove it...gotta save weight, you know![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
ETA: Somebody posted this image of the installation sheet with the wiring diagram:
