I finally got my RAC pitch trim servo speed controller so I spent my evening working on my “micro harness” for the trim relays, speed controller, and cross connect to the stick switches. Fun with a bunch of little tiny wires.
My Hartzell constant speed prop was delivered today. I also got my new engine mount and drilled gear leg (deleted from the finish kit due to the subaru mess).
Still just pulling one wire at a time. The only pictures that I took are of the glare shield dimmer and landing light wig-wag module. The diode is used in the wig-wag circuit so I can use just a single switch with the off position down. One might notice that I chose to simply bond the glare shield light inverter to the back of the sub-panel with “shoe goo”. I ran out of the shrink tube for my lable machine and 22ga wire.
I ran the wires for the avionics buss primary and alternate feed. Both of these are wired through a switch on the panel. The primary gets wired through a big power diode that I spent a bit of time trying to figure out where I was going to mount. I also made up a couple of fusable links (using instructions on B&C website) for the main and aux alternator field wires.
Just pulling and terminating one wire at a time…
Now that the engine is staring at me from the corner of the garage, I’m very motivated to stop slacking and get to work. I got the engine controls fitted in the panel bracket and the support bracket at the sub panel extended down a bit since the panel is lower than stock. I also got the adel clamp locations drilled to support the cables. I worked out the cabin heater cable, cutting it to length and putting a z bend in the end for attachment. I just so happened to have the perfect z-bend tool from the R/C airplane days. I’ve been thinking about how exactly I was going to transition my wiring bundles at the firewall into the center tunnel. I decided I would cut a slot for some flex conduit in the tunnel cover. I did one last “gut check” before riveting all of this upper structure together. I’ve been putting it off for fear of making something more difficult to work on. However, I’ve found myself spending more time trying to keep things removable for just a bit longer than just getting to it and accomplishing stuff. So, with much of the electrical equipment mounting taken care of, the center cutout for the radio trays done, and a ton of other little things pre fitted, I decided to go ahead and rivet the upper sub-panel assembly into place. No more “trial” wiring runs and “pre” fitting of stuff up here… Many thanks to Tanya for spending an hour of her Sunday evening helping me do battle with some of the rivets.
