I have a Hunter 260 and would like to add a house battery. I have a Mercury 15 hp outboard connected to the battery that came with the boat. There is a has a solar panel connected to this battery also. I assume that this battery connects to my 12 volt panel for the
lights too. da! I would like to move this battery to the port side and to just work the engine. Add a large house battery to starboard side to run
lights and stereo. I know I need a battery switch and have found one with off/1/both/2 positions. Is there a way to do this and still get the engines altenator to charge both batteries when needed? Like putting battery switch on both when running engine? I would like to leave the solar panel connected to the house battery. Any and all help would be greatly appreciated...BLUESKIES AND HIGHTIDES...RB
