Ron,

Sorry you are still confused and hope I haven't
added to it.

Great! That is the manner in which I believe it
should work.

My guess is I should look for some leaks and fix
'em. That will be the next project.

Typically, the 110V compressor is not on the
inverter so you need the 12V compressor whenever you
are not connected to shore power or the generator is
not running.

When our 2000 was new, BB replaced the 12V 4 or 5
times under warranty. I thought there has to be a
better way, especially when it became my nickel. The
switch was simple, cheap, and I haven't replaced a 12V
pump since.

Glad to try and help. I think you have it.

John
