G'day prd,
Image shows new solenoid with the earth lug on the black & white wire.
This is also how Bondys solenoid is wired in his images above.

I wasn't going to add confusion by talking about charging yet.

Regarding circuit protection.

The concept formula is:
Load current < or = fuse size < or = carry carrying capacity of cable.

load current in amps (must be less than or equal to) fuse size (must be less than or equal to) what the cable an carry in amps.
