Circuit protection on a BRIG Falcon 330 - is there any?

[TwoHooter]

I am designing some electrical additions to our BRIG Falcon 330 tender and I cannot find any fuses apart from those in the Suzuki motor.

Power goes from the battery to the console and then to the Suzuki control box and the single OEM electrical accessory, a red/green nav light on the bow. There is a circuit breaker on the output side of the switch for the lights but that is the only protection I have found.

There is no wiring diagram in the owner's manual for the RIB. There are wiring diagrams in the Suzuki Service Manual which a forum member very kindly gave me, showing a 30A fuse for the starter circuit and a 10A fuse protecting the CPU, but I think those fuses are on the engine.

Is it possible that a RIB would be built with no circuit protection between the battery and the electrical services?

Pictures show the battery compartment and the control box - I wonder if there are any fuses in that?

Update (I can't see an option to edit my original post) - the 10A and 30A fuses mentioned above are definitely on the engine and the parts manual shows a 10A fuse in the control box but it's not clear which circuit it protects. So I suppose the idea is that Suzuki have provided sufficient protection for the engine and since BRIG have only installed the red/green navigation lights the breaker on that circuit is all that's needed. Hmmm.
