In below pic you see a black fuse holder that contains a 15 amp blade fuse. You also see a blue holder which contains a 40 amp fuse.
Is this normal to see on crank batteries?
Can you speculate what they may be for without tracing wires?
Their wires lead into a large set of zip tied wires that make me nervous.
