I'll loom that wire. Otherwise, I've been running breaker-open most of the time due to fire concerns before I had someone qualified like yourself look at it. Am I good to go to run it hot all the time?
Also, how much waterproofing do I need to do to it as far as rain or river crossings are concerned? I won't be submerging up to the headlights or anything crazy like that but it still remains a question mark. Thanks |
You can run it hot all the time... nothing wrong with that. Fire risk is minimal here.
The only time you have to really worry about being hot 24/7 is when you have larger persistent loads that are connected to it all the time. If that is going to be a normal operating condition, then you want to add some battery protection device like a LVD. This is even more important on a single battery system vs a dual battery.
You don't need that much waterproofing... the main reason for all that stuff is to help prevent moisture ingress into the open ends of the wire/terminal to combat against corrosion which would lead to performance issues in the future. This is generally why everything you see in marine applications are tinned.
If you are talking about submerging to the level of where your aux fuse panel is... I think you have other problems you might want to worry about first lol.
This is all low voltage DC... risks across the board are low when it comes to waterproofing.
