Wiring question

[pelican]

A fused busbar is the only way to go IMHO. A little more wire in the bundle, but much easier to isolate and troubleshoot should the need arise. I found that fuses on the console next to the switch tend to corrode a lot faster than protected fuses. Make sure you keep a dry record somewhere of which terminal feeds which unit. I also "bus- barred" all my ground leads individually. One open ground on a daisy chain and lots of stuff quits working! Remember, anywhere two pieces of wire come together open to the air is a corrosion site waiting to happen. A well protected busbar coated lightly with a good corrosion preventative can help eliminate a lot of that. Just MHO

that's good advice - but - the picture's terrible.evey connector isn't protected - connectors need to be heat shrink sealed - this will oprevent corrosion - by viewing the picture,it's clear the connectors are not properly sealed - sorry bro...
the screws - holding connectors to either the ground buss,or the fuse box - it's a good practice to get into,coat the threaded area in liquid electric tape,then install the screw - this will prevent the screws from vibrating loose - a common failure point.
those "main" power and ground wires - these should be secured,not free to flap around - if left in their current state - the connectors will fail,due to the wires swinging around...
wire ? what's that wire ?
