How do you charge the batteries.
If I have shore power ON and Battery charger turned on, do I have to turn the battery knob in the back to a certain battery or even have it off for the charger to charge. The other day the batteries would not start the engine, just a click. There's something about running the fridge that will drain the batteries the last owner told me but not sure if I have it right. I left the fridge switch on and thinking maybe the shore power would run it. The fridge is AC/DC type. I just started leaving the fridge on and now the batteries are low. The bilge pump, radio, toilet, galley pump, and lights all work. I have a 2005, Fiesta Vee 2700. Has anyone had this problem?
