12V battery Bay

[AndyRonLI]

So.. you dont work from wiring diagrams ..fine
But could you label the damn things! The battery bay is a rats nest!
I have sort of pieced it together, but not sure I have it right.

Oh and could you ask your techs if the could maybe put things like the converter where one doesn't need to hire an orangutan to reach them!

Keystone has at least standardized wiring colors for the 12V system which IMO is vast improvement over my previous RV which had NOTHING standardized.

SO for most of us, any upgrades we make will be battery, inverter, charger, transfer switch, solar charge controller. All on the upstream side of those coded wires. Were does the solid blue wire go to in the battery compartment.
Where do each of the three 6 gauge red wires go? etc etc

Frustrating

Someone asked that same question before.
Blue goes to the trailer break away switch.
The red one with the 30A inline fuse goes to the solar wiring (MPPT) behind the basement wall.


Red self resetting circuit breaker 12v, 30A, 10 gauge wiring.

Blue: trailer brake away switch.
Tan: ?
Purple: ?
Red 1: ?
Red 2: ?
Red with inline 30A fuse: to solar MPPT

My main 12v battery bay question is are all of the 12+ copper bar "grey plastic" automotive self resetting relays 30A, or is there a larger one for the 4 gauge red power from the inverter? I am getting up to 60A from my 4575A converter recharging my soon-to-be 400Ah battleborns, and want to make sure the relay - fuse isn't blown. Some have had issues with it blowing, and I don't want to disassemble the entire bar to see what A the charging relay - fuse is.

I am about to move the PD charging wire to a new resettable 80A relay then feed it to the copper bar, but don't want to mess with it unless needed.

Thanks

My 30A red self resetting circuit breaker failed. I replaced it with a Bussmann 50A for the converter wire.
I rewired the battery compartment when I added the 80A hydraulic system breaker and the 200A inverter breaker and the bus bars. All of them are Bussmann products.
