Using the outboard to charge battery
On my SailMaster outboard it has a charger in it for charging the 12v battery. I took a reading with the voltometer anf it is putting out alot more than 12v. I am thinking that when it is hooked up to the battery it will put a load on the charger and do what it is supposed to. Is this correct. I have read that people use the 12v outlet in the cabin to connect to the electical and charge the battery from there. Will this effect my other wiring in the boat? Will it cause any damage to my wired in xantrex shore power charger? I do alot of night sails and would like to keep the battery up and the lights on.
