Thanks Bob. That was also my decision when powering the systems., primarily for having the battery on line but seeing all those other 'smart' TC folks do it the other way was confusing me. I'm doing it your way!

If you hook ground power to the battery side of the
GP_Contactor, you can charge the battery without
powering up the aircraft. Further, you would not
be able to hook ground power to the aircraft WITHOUT
having the battery on line as well. This would be
my preferred configuration.
Production TC do it both ways but predominantly
the OTHER way. I'm mystified as to the rationale
for doing it the other way . . . somebody made
that decision long before my time and isn't around
to explain it any more. I'm unable to deduce
any advantage that would give it precedence over
the first way. I am presuming that they had a
"good" reason but I don't know what it is.
