ARB fridge stopped working off battery???

Ultimately fuses or other OCPDs are to protect conductors.
20A will be fine for protecting your 8AWG wire. Further, it will protect the appliance cord if it sustains a short circut.

Thank you for all the help I’ll grab a 20 amp and go!

Well that’s a little bigger than I need! Do they even make a 15 amp fuse for this big boy. ???View attachment 653784

That's like the Fuse holder on my 26A Noco Charger, HuuuGe

Cool so what do you think was the problem ??

And How is the Voltage Now, ?

Was it the primary wire? If so I would advise to remove it to prevent future mishaps.

Voltage is constant at 12.7. As to the source ?‍♂️ Maybe the harness was just old. I’m also ordering if my solar panel might be masking a bad battery.

Cool so just from changing the wiring the voltage has gone up from 12.3v to 12.7, Going to the bigger wire size would of boosted the voltage higher, Thats going to preserve the fridges electrics for sure. Well Done Sir.

changing the wiring the voltage has gone up from 12.3v to 12.7,

When the Fridge was pugged in the voltage was dipping as low as 2.3

Mine using cheap wire will drop around 0.23v with proper wiring it drops very little, I haven't checked it with good wiring but I will test it out some time,
