Re: 1 Main Rocker——4 Sub-Rockers....How many Fuses?
You have 4 circuits. They should each be run thru a fuse block, with the + and - running back to the battery. A main switch, or a relay can power up the fuse block.
The 12 v to the fuse block can be fused, also--mine is--but I think it's redundant.
