No 12v at all

[labelguy]

Can any members help with this one?
Last time we used "Paddy" our 2014 Niesmann & Bischoff motor home everything had been as normal with the 12v and 240 mains hook up. I powered down as usual when leaving him at the compound but when I returned just 24 hours later the electric step didn't work and when I eventually got into the van I had no power on the main instrument panel at all so couldn't put lights/water/or anything at on. He started first time and the cameras worked but not the radio, I drove him home and when I plugged into the mains 240 feed everything fired up as normal. unplugged and lost everything again. Has anyone experienced a similar problem?

Dead hab battery ! ? Unless you have isolator /fuse at battery before take off connection .

thanks for coming back, voltage shows OK and new-ish battery but possible. i was hoping it may be a hidden fuse.

Main Fuse - 50Amps maybe, but it will be close to the hab battery. What is the base vehicle?

If your n+b was like mine the megafuses are all by The cab battery in the floor passenger side Fiat Ducato .

Fiat Ducato, I have checked the obvious fuses, 50 amp being one and all are good. It may be a hidden fuse or as suggested a newish battery may have failed. Thanks
