Mark,

the set up is such that when key off then the car works just like it
normally does except that the juice is coming from house battery  not
the starting battery.

no other voodoo or complication, just as if one had one battery.

but when the key is turned on it connects the starting battery and
the starter and the house battery are all connected (and fused)

I am curious whether you ever thoroughly checked during darkness to see
what would work and not work with just one battery and then just the
other.
