Brief Description:  Wire bundle organization

Today I spent a couple of hours running through my electrical plans to determine if I had actually run every wire that would need to be routed through the forward fuselage. Thank goodness for the time I’d spent (most of it not included in this log) putting everything down on paper as there were a few that hadn’t been run yet. I still needed grounds for the master switch and ignition switches, both of the pilot and co-pilot PTT wires, and the lead from the ELT to the panel.

The ELT to panel lead is simply what I would call phone cord—four 26 AWG wires in a black sheathing with modular phone plugs on either end. After cutting off the end (since it would never make it through the spar) this was routed through the spar and will join the RG-400 cables in a separate bundle that will be zip tied to the main bundle using standoffs—a technique that I’ve seen utilized in our Citations at work. The ground wires were simply about 5’ runs that were easily inserted in the existing bundles, the PTT wires are a little more work since I’ll have to loosen some clamps, but shouldn’t be too difficult—the only challenge will be whether the Steinair guys gave me enough to make it to the control sticks. If not, a couple of D-Sub pins and sockets will be employed as a splice. BTW, I’m proud to say that at this point, I haven’t had to use a single unintentional splice…planning pays off.

I had to open up the P244 connector on the GEA 24 to install three pins for the Hall Effect current sensor on the standby alternator so that my G3X can read that current. Once that was done it was just organizing, removing twists, and finalizing the plans for securing everything. Getting close!
