I am waiting on delivery of a new SDX 270 with the Verado 300. I ordered the dual battery option and a charger. Outboards are new to me, and the Verado has some peculiar electrical requirements due to the ECM, digital fly by wire, and electric power steering. As I read the Verado manual, they are very specific about having complete isolation of the engine battery and the house load. When I was shopping my boat, every one I was on had the traditional A/B/A+B selector switch, which clearly does not isolate loads. Any Sea Ray / Verado owners out there that can confirm it was rigged with the typical combiner switch and not isolated? If so, anyone have any issues as a result of the combined loads (power steering dropping out, ghost alarms from low voltage, etc)?
