Electrical Distribution Panel

I deburred the lightening holes in the electrical panel, and removed all of the sharpie ink from layout planning.

Next it was time to get to work populating that panel. I started with the diode bridge for the SD8 circuit.

First up is the resistor:
SD-8 Wiring

I soldered the solid lead components instead of using the crimper.

Like this. Then I covered as much of it as I could with heat shrink.


Here’s the resistor for the capacitor:
SD-8 Capacitor

A little heat shrink will help limit shorts.

Here are most of the other components:

There are two problems here. First, I had to remove the jack on the middle of the right side. That was for alternator diagnostics, but with the Plane Power alternator that isn't available. Second, the ebus diode, just above the junction of the two fuse blocks, wasn't well enough insulated, so I changed the mounting later.


From left to right, top to bottom: Main bus fuse block, ebus diode, ebus fuse block, alternator diagnostic plug (later removed), SD-8 Diode Bridge, ebus relay, SD-8 Relay, SD-8 Capacitor, SD-8 Regulator, and SD-8 Crowbar overvoltage module.
And the back:

The components also add a lot of stiffness.


I’m attaching that panel to the fuselage tubes with adel clamps, so I thought I’d make a copy of a tool to help install those clamps. The V on the end goes into the threads of the bolt that secures the clamps, relieving tension on the nut after compression. That makes a 3 hand job into a 2 hand job.

Here’s the panel in place. I didn’t realize at the time, but it’s going to crowd the duct for the right front seat passenger vent.

Since the weather was nice I also cleaned and primed the steel straps that connect the rudder cables to the rudder pedals.

Here the other side is ready to paint.
