I have searched the site and found a ton of information on boat wiring. The following summary is my understanding:
1) Run positive and negative, minimum 8 awg, from the battery to a fuse block
(looking at this one with a negative bus bar built in: https://www.discountmarinesupplies.c...se_Blocks.html)
2) From each fuse in the block, run single wires to individual switches on the switch panel (something like: https://www.wholesalemarine.com/blue...el-6-position/)
I will daisy chain the negatives in the switch panel back to the built in bus of the fuse block.
3) From each switch, run single wires to each accessory (no daisy chaining positive wires).
4) From each accessory, run ground back to the built in bus of the fuse block and completing the circuit.
For my depth finder, I am planning on running that straight from the fuse block to the unit as it will not need a switch.
Does this thought process seem correct?
Also, is an onboard charger necessary? I am repowering my boat with a 25 tiller pull start that will not charge the batter.
