Spent a number of hours tidying up wire runs. I am looking at the plane from the perspective of an inspector and I saw some opportunities to improve the separation between current carrying wires and fuel lines.
Also attached some silicone terminal protectors on all the exposed studs on the fuse busses, and on the master solenoid.
While I'll always consider the hinged bus tray a master stroke in the panel design, I was always concerned with something dropping out from behind the panel, falling onto one of the studs on the busses and instantly shorting the electrical system. In contrast, mounting the fuse busses vertically makes this scenario less likely.
The fix is easy enough: silicone terminal protectors. I used them on the master solenoid as well, since there were two studs on that unit that also seemed 'at risk'...just sticking out into space, waiting for something to short them
