Wired Gretz Heated Pitot Tube Output to VP System using a circuit board that converts the current signals from the Gretz Heated Pitot Tube into a ground signal that can trigger an Annunciator Message on the Vertical Power Display. Doing this removes the need finding panel space and mounting the LED lights that come with the Gretz System. I used two user definable switches locations on the Vertical Power Control Unit and one from the Vertical Power Display Unit.
I had to add a pair of hex socket head screws to the circuit board in order to be able to screw the shellback jackscrews to the circuit. Without the hex socket head screws, there was a large gap between the two components, too large for the jackscrews to reach across.
