Hi

I am hoping for some advice on the electrics of a Fiat Ducato Autoroller.

I am trying to work out the electrics as it appears to have been sliced and spliced

Does this inverter produces 240 from the 12v battery. I have plugged in a meter into the standard plug sockets in the living area and I am getting no response. The inverter isn't warm either suggesting it isn't functioning and there is no on/off switch that I can see.

I don't having the wiring diagram for the inverter so am not sure where to start in regard to tracing the power or even what the pictures relate to

240V works when hooked up
The pump works
The internal 12v lights work

any help would be welcomed like an oasis in the desert

I can't see an inverter there, just the normal 12V electrics.

That might be why. I have assumed (and everyone else I spoke to) that it was an inverter as there is some sort of transformer in it.
What would be the technical term for the black box? I assume it acts like a consumer unit for the 12v distribution? There are some 240v cables there too though?
appreciate the help

That's the battery charger when on EHU.
240 sockets only work on EHU too.

Spot on.

This might just be a technical term problem. Inverter takes in 12V DC and outputs 240V AC. Charger takes in 240V AC and outputs 12V DC.

Inverters are a can of worms though. We are so used to just plugging in electrical gadgets at home it takes some adjusting when running on 12V. The classic is The Hair dryer. About 1200 watts. Nothing is it ! But 1200W when running off 12V is 100 amps which will drain the average 12V leisure battery in 15 mins. So be very wary of inverters.

As said above, be wary of inverters until you know a lot more about them - there's a number of threads you can find by using the search facility.

We've got a small inverter but it's only ever used for charging the laptop when the sun is shining on the solar panel! It's far easier to get used to having everything on 12v.

Might be worth taking it down the weigh bridge and getting it weighed with all your bits and pieces in. These should include everything that you will be carrying including yourself,wife, dog, food, water, full tank of Derv, bedding, food, bikes etc. Etc. The axle weights on the plate. Front 1650Kg and rear 1750Kg and don’t exceed 3200Kg

Nordelectronica went bust in 2011

Nordelectronica may have gone bust in 2011 - I don’t know - but if they did then they came back, as they are running now.

My 2006 van has one of their panels, not the same one as the OP, and I have some experience now of fixing the electronics . Problem was the fridge connections onto the board are not up to the current that passes through them- fixed by bypassing the panel and putting the 12v fridge feed through a separate relay.

Anyway - back to the original question - the setup you have, where :-

- if you’re not on 230v hookup then the 230v sockets do not work - only the 12v electrics
- if you are on 230v hookup then your 230v sockets work and it charges your 12v leisure battery

Is the normal one for most motorhomes. Inverters to take 12v DC up to 230v AC are not usually a standard fitment and come with warnings as others have said.

I take it that this is an older van? What you have there looks like a cruder version of my electrics. In my case the control panel on the wall is just a front end to the main electrics, which are all on a panel that looks rather like a more complicated version of the one you’ve posted a picture of. This takes the incoming 12v feed from the vans alternator, as well as a 12v feed from a separate transformer that steps 230v ac down to 12v - and then supplies this via various fuses to the different circuits around the van.
