I think (hope) LittleBill meant “Put the output of the DC-DC charger on the main lugs of the secondary battery”
Now I'm even more confused. How can I charge the secondary battery if the input and output are the same? =)
The DC-DC charger will have power input connection and power output connection.
Connect the input to the start battery. Connect the output to the accessory battery.
Remove the other charge control relay.
yea don't do this, this will kill the start battery if you run down the secondary, not to mention the constant drain from the charger running all the time
