Can you clarify something, as my interpretation of what you wrote does not jive with the diagram.
You say with the exception of the BAT terminal. The way I interpret what you've wrote, is there is only a single wire coming off your Bat terminal. Is that correct? Or does it have two wires as the diagram you posted shows?
Because if you have only 1 wire connected, through that 40amp fuse you are way under fused for your alternator. And as Vettevet said, your inrush is likely blowing your fuse. Unless you are taxing your alternator to the limits, a 120 amp maxi fuse should do.
