Interesting thing while testing my pitot heat. I hooked up black to ground of my power supply, red to positive and light to white and all worked well. I then decided to test the ground to the airframe since I am pondering whether to run a ground line to the pitot controller or locally grounding to the airframe (metal plane), the battery ground will be attached to the airframe. Well I had not yet connected the controller black wire to the airframe and I hear the pitot controller kick on, hmmm. It seems the controller box which is attached to a wing rib is making a ground. Should this be happening or do I have something wrong inside the controller box?
Thanks for any help. :-/
