SN 200 had to change the alternator red cable with in-line 100 amp fuse which blew.

I had to change out my alternator red cable with in-line 100 amp fuse. What I thought was odd was that the alternator black cable also had an in-line 100 amp fuse, and both connected to the starter. The black cable had Y split and was hard wired into the starter itself. I am thinking the black cable only acted as a ground, but why a 100 amp fuse? And same for red, alternators usually put out only 20 volts so why so high a fuse? Anyone else had to do this? Any ideas. Once replaced it runs fine. Had to replace the battery and alternator itself which probably blew the fuse.

    Basic misunderstanding of electricity. Voltage is not what you fuse for, it's amps. Still no idea why ground is fused.
