Is this a good way to wire things?

I have an old 1973 Mon Ark that I have been doing some remodeling on. I don't know a whole lot about wiring and this boat has been wired like this for many years. The first picture is a ground wire that goes to the negative post and it is grounded to the aluminum seat. The second picture is a little fuss box that has an extension cord that goes to the positive post and the wires from it are split to the box. The third picture is how the extension cord connects to the positive on the battery.. Is this a good way to wire things?Attachment 329515Attachment 329516Attachment 329517

I would say buy a bus bar wire positive to one side and negative to the other and run power off of that. Fuse everything going out of the positive side I just used inline fuses. I wouldn’t ground anything to the boat.

Here is what you need to get. And like Cherokee said, no ground to boat. Use 8 gauge from battery to fuse block.

Yep cray is right,fuse block is probably better way to go but I already had a bunch of inline fuses so that’s the route I went. Not that expensive to upgrade the wiring and you can do it your way.

Thanks guys!

I think I can hand taking the 8 gauge wire to the block for the ground.

Do I keep my positive extension cord wires and connect them to the new fuse block or do something entirely different on the positive also?

The wire you have should be heavy enough to run to the fuse block from the battery. You could probably use the wire you have to fish new wires into their place and then you would know what you have in case there are any other odd grounds or splices.

This may seem like dumb question but hey I'm an accountant. I only one run one positive and one negative wire to the fuse block correct? Do those wires need an inline fuse or is the fuse block providing that purpose? I ordered the fuse block suggested above this morning.

Sent you a pm

We probably have very similar boats

I seem to recall the ABYC standards indicate that circuit protection needs to be within 7" of the battery ... (Circuit protection is to keep from frying the wires if the battery shorts) ...

If your fuse block mounting is farther than this - you might think about adding a circuit breaker at the battery post to protect the circuit from the battery to the fuse block ...

Here is what I would use. It’s a auto reset and can be found in Walmart sporting goods in the boating stuff. Or a auto parts store. Use a 6 inch piece of the same wire going to fuse block from breaker to positive post on battery.

Ideally you would want a main circuit breaker/fuse close to the battery, in addition to the fuse block that you ordered.

I have a switch on my boat that cuts power to everything except motor and automatic bulge pump many circuit breakers have a switch on them as many electronics will still pull juice if shut down.
