On a more important note:
A 70Amp alternator is undesized for charging a 220Ah house bank and

I initially read your name a No Logic which is appropriate as there is
no logic to your reply!

I have a 60A alternator which happily fully charges my 330AH domestic
set under my normal cruising pattern.
Charging batteries is dependent upon three parameters, the voltage,
the current available,and the time,availabl,e saying that a 70A
alternator will not charge fully is nonsense without knowing the other
two parameters!
