Need advice. I have two 4D batteries. One for port engine, one for starboard and house. I have issues when starting the starboard, the tv shuts off, sometimes the radar, etc. So, i'd like the set it up so one battery starts both engines, and one is for house only. The issue comes with how to charge the house battery. Is it as easy as pulling the alternator wire off starboard starter and running to other battery? And leave port to charge the engine batt? I keep searching these forums, but, can't find an answer. Thanks. Mark
