Ignition Breaker wire isolater

I ended up putting 3 mechanical breakers on the co-pilots side console for the ignition coil packs and two ignitions. These circuits are fed from an essential bus sourced by either the aux or main contactors in the rear of the aircraft. Both of the buses are connected to a schottky diode which means that if there is ANY power in the system, it will feed the essential buss.

I opted to not put any of these flight critical items on the VPX. I also opted to keep them out of the AUX fuse block because I wanted them to be in-flight resettable. On my first installation of this setup, I was uncomfortable that now my safety came down to a single yellow ring terminal and a dangling wire. There was no real great way to isolate movement of that cable. After a couple of goes at various circular connectors and adel clamps I came up with the following design:



In this approach I removed all connectors and wired everything direct to the breakers, but isolated movement of the cable with a standoff that I could solidly mount to adel clamps to. Out of the design and into metal it goes.




Probably a little overkill, but why not when you have the tools, the software, and some spare time on the plane for work.


I suppose I have to grab another photo yet of the final install, but here it is for now.
