No power on dash or ignition

[Derp]

Hi there,

I replaced the starter battery less than 2 years ago, I used the vehicle last week all fine
Now it's completly dead, central locking doesnt work, no dash lights nothing.. completely dead
The solar controller charges both batteries, on the solar controller display the starter battery just isnt there anymore as if theres no battery installed.. On the hab control panel with red/orange/green lights for both batteries.. nothing shows for start battery not red or amber.. Nothing

Multimeter shows the battery to have 12.8v.. the battery is located under the cab floor.
Does anyone know where the battery fuses might be or have any other ideas?

Thanks

If Fiat Ducato based ,The main fuses should be midi type that are on the starter battery positive terminal plate which you can check for continuity using your multi-meter, It would also be worth checking the negative cable connections at the battery/body for tightness.
