Hi all. Have a question for the 12 volt wiring experts. My trailer, a 2014 roo 233s is now equipped with 2 6v batteries with an external battery shut off.
My local auto house made me some custom length 4 g wire for this setup which I ran to the original position under the trailer, a soliniid of some sort.
From this point on, the cable goes down to 8awg and is ran to the interior switch.
Should I have another piece of 4g ran to the 8955 WFCO converter? I will likely eliminate the interior battery switch if I go this route.

Not a great idea.

BAD idea to have coated it in whatever goop you spayed it with as the circuit breaker is located in the side of the unit. It may not pop out if it is overloaded/shorted.
Running a heavier gauge wire all the way to the converter is not needed.
The coach should never pull the kind of amperage larger cables could carry.
The battery shutoff should not be removed either.
However, those exposed 12 volt terminals should be enclosed somehow for corrosion prevention. The original rubber boot was most likely tossed by your installer because it no longer fit with the new heavier terminal.

It is a battery terminal protectant spray. I will wipe is off from the short stop.
I was just worried about having mismatched sized wire from my battery to that "short stop."
4g is all I could have made and I did not want to go all over town looking for the wire and terminals I needed.
There are rubber boots I am looking for that go to my battery disconnect switch.
Herk, if I installed another shut off/disconnect outside, why would I not be able to get rid Of the one inside? I am curious as this rv wiring and converter stuff is fairly new to me. I am trying to eliminate failure points.

So, without a good wiring diagram of how your battery bank was wired, it is hard to tell if the interior shutoff switch is still needed.
Is there anything between the new shutoff switch and the batteries? Is there anything between the two switches that should be (or you would like to be) powered when other things are isolated? (Like clocks, slides, or propane detector?)

IMO, the new one was the one to be eliminated since it is before the fuse; but if that is not an option I would just leave it alone. You should definitely cover the exposed 12 volt "un-fused" wire terminals at the new switch since a short there will cause a fire without fuse protection between there and the batteries.

Hmm, I was just trying to eliminate parasitic battery drain and I thought by installing the disconnect between my batteries and everything else was the way to go.

Well, you accomplished that. Just saying the exposed "hot wire" can cause an unstoppable short if it occurs there.

Sounds good. It will not be exposed as I have rubber boots made for that switch that just did not get sent with them. They install on the wire and will cover the posts of the battery switch.
I guess I could have eliminated all of this by installing the disconnect to the negative side.
Thanks for all the info and guidance Herk!
