Electrical novice needing help...
My RV-9A does not have an E-bus (endurance/essential), just a switched Battery Bus (master switch) and a Avionics Bus, switched through an avionics switch. All circuits are protected with hard-to-get-to-but-still-inflight-accessible fuses.
If IMC I want the ability to kill power to everything but the essentials to isolate shorts while aviating and communicating...near impossible to do in the current configuration, certainly not quickly while maintaining aircraft control. The new E-bus will have CBs or easily accessible fuses.
I'm using Z11 schematic as a starting point, but I want to change a couple things...see pictures...changes are in red.
- I removed the Hot Battery Bus because all I need is the E-Bus feed
- I removed the Diode and replaced it's function with the STDP switch thats ON/ON, so the E-Bus is fed by the normal switched Battery Bus OR directly from the battery. This will be a guarded switch.
- Increased to 14AWG wire to handle greater load requirements and longer wire runs.
Is there anything I'm missing? Is the diode still required? Do I need further protection somewhere? Will this kill me?
