Brief Description: Wire routing and alternator installation
|
|
The first hour or so this morning was spent working out some thoughts on how best to install the various boxes that power the G3X avionics suite. Since the wire bundle was made by SteinAir without the benefit of actually fitting it to the fuselage, I now have the task of figuring out where everything will fit. The G3X Touch makes the panel very clean by having both the radio and transponder remotely mounted. Since I don't actually have either of these boxes yet, I am relying on the installation manual for dimensions, but even with this, it's a little hard to visualize where they will go. I'm actually thinking of making cardboard mockups to facilitate the fitting until the actual boxes get shipped in March.
No wanting to leave without actually building something, I decided to fit the alternator. The alternator is attached with a bracket that mounts in a very specific place on the lower right side of the engine, so there aren't any options on locations for that. The plans suggest installing the alternator prior to fabricating the inlet air box due to access issues once the alternator is installed, so that made it a logical task to do next.
The first picture shows the primary attach bracket. This is held in place by two 5/16" bolts that require safety wiring. It’s been awhile since I have had to safety wire anything, and like riveting, it is both an acquired, and perishable skill, so after torquing the bolts, I practiced my safety wiring. When I was satisfied with the results (attempt #3, I think), I put the alternator on and finished up for the day. Lots more wiring—of the safety and electrical kind—to come.
