Ok, guys, it's the rookie boat owner. I'm replacing the bottom flotation
foam and floor in the old boat I bought, and thinking I need to check
wiring while it's all apart. There are no fuses. I do a lot of work on
electrical wiring from 120v all the way to 480v 3phase, but don't know
much about 12v DC. Is it common to go without fuses? It is set up with 2
batteries. One has the trolling motor wiring going through a bigfoot
switch and directly to the battery. The other battery feeds 3 switches
which feed lights, live well, and bilge pump. I suspect the answer I'll
get is that I need to add fuses or breakers of some sort. Next question:
If I do need to fuse them, do I just need one large fuse per battery, or
seperate fuses for each item. Thanks in advance.

Henry
