disconnect
With respect to Steve D and others,
It's hard to fuse between big engine cranking amps and a "dead short".
There's no such thing as a dead short when you compare to a nominal
starter cranking a big diesel. (of course, battery cable must have a clean
and safe lead to the starter but even if it didn't, how would it chafe enough
to draw more current than the 800A diesels starter?)
You can propose a "just right" fuse ,but
you will have to deal with the "I can almost start it", vs an an almost
perfect short. Not gonna happen. The bigger issue, if you want to find one here, is if the starter solenoid contacts weld and you are drawing 800-1000A continuously. How will you quickly disconnect? Can that Perko switch be
rotated away from welding contacts? (I have not had the unfortunate
situation to test, but I do have big cable cutters at hand for the worst case.)
