Having just fitted shore power, I'm now looking to fit a battery charger but how do i wire it in to the batteries circuit?
Current set up is single alternator running through a battery isolator diode (sure power 702R) to two batteries. I understand the diode not only seperates the batteries, but directs the appropriate alternator charge to whichever battery needs it.
If the charger only has one outlet do I wire it in above the diode so the diode directs the charge to the approriate battery (like it does already from the alternator) or would the current drawn by the diode "fool" the charger into thinking the batteries need more charge than they actually do and thus the charger keeps pumping out a higher charge current instead of switching to "trickle" mode?
On the other hand if I wire it to one of the batteries (after the diode) then would the charger not just charge that one battery as the diode would prevent the charge getting to the other one....or does the surepower diode have some clever trickery that opens to both batteries when it senses a charge to one?
Thanks in advance
