Andy, I wonder if our batteries can really put out enough juice to fry the circuits of a functioning device. I can see it on a boat but with a simple battery circuit and no potential capacitance elements, I'm not sure where the surge would come from, unless the device itself had already taken a crap. I guess that's my question, is the fuse there to protect the device in case the circuit fails, or is it there to protect the boat in case the device or circuit fails?
