 |
|
Bob:
On my RV-9A I have 3 switches on my Pilot stick grip: 1-PTT, 1 - Autopilot
disconnect and 1 - Com Swap switch. I have a couple ideas on how to ground
these 3 switches and would appreciate your comments, thoughts and or
suggestions.
1) I thought about a terminal block next to my stick mounted under the
floor - 1-22 awg wire from firewall ground block to terminal block, then
connect the 3 switch grounds to the terminal block.
2) use a terminal block under the stick as my connection point for all 3
ground wires from the stick, then run separate wires (3) from the terminal
block back to the firewall ground block.
Thanks for your input...
Henry

I'll chime in as I have done this.....
My variation of #1 has the grounds on the frame right there - without the wire all the way back to the forest of tabs. The contact is momentary and low current - my reasons to keep it simple

Ralph, Would you use a terminal block or just ground to the ctr spar or
floor stiffner?

I used a terminal block - for the 'hot' side of the stick connections anyway
and had a few lugs left over. This allows me to remove the stick wiring
seperately. The grounds from the lugs went right to a floor stiffener.
