Reversing the charge scheme (putting the Eco-charger on the house bank) would severely limit the rate at which the house bank would charge.
The purpose of the Eco-charger is to ensure the start battery is not cooked as without it, the start battery would be charged at the same rate as the house bank. If, as most of us do, you have a large house bank, large charging source and a somewhat depleted house bank, the net flow of current into the house bank would be at a rate such that the start battery (presumably not equally discharged) would suffer.
In most respects, every boat should be able to start off a house bank if necessary. There is nothing sacred about a fully charged start battery as long as you have a means of switching over to a house bank for starting when needed.
So the dunb newbi needs something explained to him,
Way i understand this the charger charges one bank to max the kicks to the other.How does that fry a start batt if you reverse it?
