Fuse size & wire gauge

Are all connected devices working?
I would take the time the trace each connection and label them and draw a diagram.
At some time, start cleaning up the wiring will better crimp, shortening wires and securing them
 
Check the Practical Sailor testing of several anti corrosion products I seem to remember that NO-OX-ID was made with grey aluminum powder for home wiring an did not do well when mixed with copper and salt air. I used it until reading the review and have gone over to the insulating non metallic, more water resistant qualities of silicone diaelctric grease
 
Chester, it was good of you to find that article I was too lazy to drag out all my old issues to find it and using my phone gets tedious.
I see that I was using Noalox it's been a while and I had always used it wiring houses where it is very common.
Practical Sailor seems to like Green Grease which I wouldn't expect, I've used the lanolin based water resistant Lanocoat but I always thought that it was too messy for wiring. I wish they would test my favorite silicone diaelctric grease that I buy in large tubes at an electronics supply. I have done extensive wiring with it on 3 salt water boats over the last 15 years and on the Ranger Tug with a crazy amount of wiring and electronics under the leaky cockpit hatches it really saved me. I also find it works great on water filter o rings, hatch gaskets, stainless threds and sticky window slides, being muti-use it makes the cut for our limited storage space.
Thanks again!
 
You may take this into consideration
To find the total amperage in your specific installation, refer to the table below. Find the items that you're installing and their current requirements. Add the values and divide by 1000 to get your total current in Amps. You can use this value in the fuse size chart above to determine the minimum wire size required.
