Hi Tony, We'll I'm here ! Vida~Nueva is fitted with a 'Power Master' battery charger. The instructions that come with it make interesting reading. It has an equalising charge of 14.6v and a floating charge of of 13.7 v I have made the assumption that it is all automatic and as so far boat has not left the Mercia Marina very much, due to the ice, for most of the time it has been hooked up to the shoreline. Until very recently I did not connect the shoreline to the charger or anything else for that matter, as our surveyor wasn't totally happy with the way the Galvanic Isolator was wired. I think he was concerned that there was no bonding cable connected from the hull onto the boat side of the earth connection. I had doubts about all this, so now I have a proper isolation transformer which as far as I can tell, is doing it's stuff. I now feel more confident to leave the charger connected all the time(while still connected to the shoreline !) I am aware that the charger is operating, because in the dead of night, I can hear the fan working, which soon stops after all the cabin lights(LED downlighters) are switched off; eventually it comes on again, I presume the fridge has cut in(the shorline fridge is lovely and quiet !) Do you think it is desirable to leave the charger permanently switched on, as it is a fully automatic model ?
