Vehicle battery showing 0 volts on control panel

[WillandLes]

Hopefully someone can help with this one. I have a Fleurette Magister and yesterday the control panel showed 0 bolts for the vehicle battery. The engine starts ok and the across the terminals there is 12.44 volts. One of the connections from the positive terminal also shows 0 volts and I have 0 volts from the vehicle battery at the shunt (where all the fuses are located). See photo of battery terminals. It is the top one showing 0 volts. Is that a fuse next to the terminal? In which case maybe a fuse had blown.
I also have a problem with the fridge not working at all so maybe the two issues are connected. Any help/ advice would be gratefully received.

Check the fuses for continuity with a multimeter

The red plastic piece with 2 x screws near the terminal is not a fuse (it just helps keep the terminal plate in place) . As Jev88 has said check the Midi fuses for continuity and the tightness of there connections.
Which make and model of PSU is fitted.

I have checked fuse and it has blown. New midi fuse ordered. Still not sure about the fridge. Maybe a new fuse will surprise me with an unexpected solution

You need to find out what has blown a 50 amp fuse , unless you already know, as it takes a lot to blow a fuse that size (perhaps it could be the fridge being faulty blowing the fuse as it will be connected to the starter battery for its 12v operation when the engine is running , although it should have its own fuse, if a 3 x way fridge)
