For some reason ( and whilst en route to Spain) we stopped for the evening
and found our door step wouldn’t work nor the fridge go on gas , no lights, heating panel not illuminated.
The electric hook up light on panel (which we are not on) is illuminated.

Starting the engine everything seems ok Lights fridge on battery etc.. just when the engine has stopped.

I’ve checked the fuses on the Ekektro block and adjacent to that the reset button and switches ( On the Domestic unit * not sure of the correct name l’ve switched all on the up position alas back at square one .

Any help would be appreciated ?
 
If all else fails turn electro block off, count to ten and turn on again it has fixed issues for us

similar with the big fuse we have next to it, 50A I think , pull that and similar count to 10 before replacing

simple things first ?
 
Is there a big fuse at the leisure battery? Sounds like things work when the engine battery is linked so perhaps it is something between the leisure battery and the EBL.
 
Thanks, Done that and checked 50amp and all aux fuses but nothing .

When l switch the engine on all is fine .. Habitation battery is good 12.v

Really at a loss ?
 
Just checking fuse on Hab battery

Yes all fine on the fuses Re Hab battery
 
Is there a small 2A fuse next to the 50A fuse? If so, worth checking.

What model number of EBL is it? The battery on/off switch on some EBLs is notorious for being iffey. But usually it won't switch back on when it has been switched off.

I'd guess it's a problem with the main positive supply to the EBL, or maybe even the negative supply wire. Did you measure the hab battery voltage when the engine was not running? Do you have a multimeter?

We had what sounds like a similar problem with our EBL99. when the 12v was switched on at the panel and on the electrobloc, we had no power at all, everything was dead.
We had it checked out by Tommy at Camperserve in Portugal and it turned out to be a stuck relay in the EBL. Not sure exactly what he did to the relay to get it working again, but it's been fine ever since.

as soon as I read it a faulty relay came to mind
 
I had similar so I emailed Schauldt through their website and received a reply the following day. In my case it was the 20a fuse on the van battery.
Good luck.

Thinking about it, all the EBL functions are controlled by a small silicon chip, that also monitors the mains charger and sets the mains hookup indicator, which you say is erroneously indicating hookup power. It controls the two large main relays. The relay controlling the step and fridge should always be on, even when you turn the hab electrics switch off. So that silicon chip must, to use a technical term, have a topological misconfiguration of its underwear.

You need to try to reset it, as DavidG58 has already suggested. Powering off and on again is worth trying, but that's easier said than done. Is there an isolation switch by the hab battery? If not, pull the large fuse (30/50A) and the small 2A fuse next to it if there is one.

There should be a big fuse and a small fuse, maybe 30/50A and 2A, near the starter battery, which go to the EBL. Also near it should be a 20A fuse that powers the fridge while the engine is running. You could remove all these to be sure of cutting all power to the EBL.

Note that simply switching from the front of the EBL will not do it, because that switch just sends a message to the silicon chip to cut the power, and I think the silicon chip is in an erroneous state.

If You have a long jump lead put a clamp on the NEGATIVE of the leisure battery and the other end under the van on the CHASSIS to a bare metal bolt etc.
If the camper stuff works again You have a bad earth.
Had a NEW van, everything worked on 240V and Engine but nothing on 12V. The leisure battery was grounded to the chassis but the chassis ground had broken off.
The other week same thing on a mates van but this time the chassis ground had corroded, NO EARTH = NO CIRCUIT.
 
Thanks to all for your help . As you may well imagine en- route and then finding you have no electric then it’s like Sherlock Homes trying to find a cause .. You try everything check fuses , reset consumer unit to no avail.. contact Shaulk in Germany and await a reply .
Drive 650 km and avoid another overnight stop with no power , Turn up on our camp hook up and ? Back to square one..

We had quite an interest in our predicament and what was causing the problem.. Then ? After removing yet again the seating where underneath our Habitation battery is looked at the 50 amp fuse that was fine but just mentioned the cables could do with being more tidier ? ( l thought) then the negative wire just simply came away from underneath the plastic housing ( top of the battery)
? OMG Eurika how could this happen but it has and this was the fault...

Sry for the long story but obviously so elated that l can now enjoy our holiday .. again thanks for your comments that’s what makes MHF such a great website for fellow Motorhomer’s

I think you're crediting the silicon (in the EBL itself) with too much intelligence. I doubt it's a CPU & memory - more likely a simple LSI chip to route switch inputs. There's normally a small cable with the EBL that can be plugged in to bypass the control panel functions and allow normal operation. The User manual has details.
