Brief Description: C/B bank wiring - pitot heat wires
|
|
The next step on the C/B bank was the pitot heat power wire to the pitot heat switch on the center panel, which will be easy breezy. But as I thought through the remaining pitot heat wiring, I had another decision to make. The heated pitot tube is out in the left wing and already has the wire in the wing conduit with additional wire for the fuselage run service looped and waiting for the wings to join with the fuselage. The question is, would I rather have the pitot heat wires in the wing and run the wires thru the fuselage later, or have the fuselage wired now and run the wires through the wings later. Since the fuselage wiring would be much more difficult later, I decided to move the pitot heat wires to the fuselage now and wire the wings later. I am glad I did, as this was no easy chore, even now, as my left side gear cradle conduit is filling up. I pulled the pitot wires out of the wing, replaced them with a pull string, and then restrung the wires from behind the spar forward through the gear cradle and up to the power switch and FOT. During this wiring, I noticed that the roll servo + co-pilot wires were running under the fuel line instead of over it - so I had to undo/redo that situation. I have way more than enough pitot heat wire length and measured it countless times, as I would like to cut the wire and terminate it at the switch and ground, but as always, I would rather have two feet too much wire instead of being 2 inches short. Not much visual progress today as there was lots of head-scratching, but getting the pitot heat wires run through the fuselage was a big win.
