Well the G3X will be wired directly to the Master switch because it has the engine gauges. As far as the Standby battery goes, I'm assuming if you turn off the master, the panel will go off too. The logic with the way Aerotronics recommended wiring it is the Standby circuit is totally separate. It goes to the standby power input of the G3X meaning if anything goes wrong with the master circuit, it will still function, thus a separate switch. This eliminates the single point of failure of the master switch and the wiring from the master to the G3X. The way you wired it directly is probably more practical especially for a VFR panel. Plus, I think that means your standby power could power anything on the bus, not just the G3X. Does that sound right? Was that your reasoning?
