Hi
Can anyone help ‘
We have recently bought a new to us 2015 Roller Team 740 Motorhome and have changed the Fiat Ducato radio for an new Anriod one ,
The new radio managed to drain the power from my vehicle battery overnight from 13v to 6.5v,
Since then I have fixed the radio problem and recharged the battery back up to 13v again, the Nordelettronica NE 268 control panel is flashing on the B1 vehicle battery button and showing a reading of 0.0, voltage , ( even though it is showing fully charged at 13v when checked with a multi meter )
I have tried to re-boot the panel several times by removing the rear supply cable and waiting for different timescales from 15 seconds up to 30 minutes before reinstating it but unfortunately this has had no effect on the problem, as it is still misbehaving in the same way
has anyone had this issue and managed to fix it
thanks for any help Paul

I'm replying mainly to bump your post up again for others to see. However from what little I know about batteries 6.5v may have done irrepairable damage to your battery and it's ability to hold the charge. Of course I hope not. 🤞👍
 
You say B1 vehicle battery.....is that hab battery or starter battery.
If it's the hab battery does anything 12v work? (Without hookup or engine running)
If not you probably blew the master fuse near the battery
 
As Landy Andy and pappajohn have said you may have lost the power supply (fuse?) but if that is all ok you could try contacting www.apuljackelectronics.co.uk as they repair these Nordelettronica units and may be able to suggest a possible reset method.(their website does list the NE268 and its possible faults)

Thanks for the responses ,
1/ it is the vehicle ( starter battery) that was discharged and then recharged, and the flashing B1 button on the control panel represents this,
The habitation battery is fine with all things 12v working ok within the habitation area of the van,this is represented by a B2 button on the panel,
2/ I will try to have a look tomorrow and see if there is an in-line fuse that may have been affected between the control panel and the starter battery

One of the odd things about this situation was when the starter battery had initially been discharged and the vehicle would not start I then looked at the control panel and pressed the B1 button to see what the Display voltage was for the starter battery and it was showing 14 V when clearly the battery was flat and this was confirmed with a multimeter on the battery terminals so it was left on charge for a few hours and brought it back up again to 13.5 V again ,
and left me with the flashing B1 button and 0.0 V reading
 
Wrong voltage readings is one of the common faults that Apluljack list. Have you tried a shutdown and restart of the Ne185 ? Power control system fuse box.

Yes I have done the equivalent by pulling the power cord from the back of the controller waiting 30 minutes and reinstating but still getting the same readings thanks
 
Battery readings of 13 and 14 volts generally only happen when the battery is on charge (usually ehu or solar ?) and may show this voltage even when your battery is actually goosed. Maybe make sure there's no charging going on and recheck the voltages just to rule out a duff battery ?
 
The fuse board controls display unit information (along with other things) so It may be worth checking the connections on its rear are tight and do not have any sign of poor connections. (If you have not done already)

Yes I’v had a good look at the back of the fuse board and checked all the connections and it all looks fine
 
If the vehicle battery was only on charge for a few hours although you saw a reading of 13.5 Volts this is unlikely to be a true reflection of the state of charge.
With the leisure battery, solar and mains power disconnected is there any 12 volt power at the NE185 ? If not I would be looking for a blown fuse close to the vehicle battery.

I am going to take the van on a 60 mile round trip this morning after after checking the electrolyte levels and topping up if required, should give it a good enough charge and I will monitor the situation after that maybe that will have some effect on the level of charge sensed by the control panel, incidentally it is the Nordelettronica NE 268 we are talking about not the NE 185 as mentioned
 
Hopefully the run out will sort things out ,but if it does not ,The reason for the mention of the EC185 fuse/Power distribution unit is that the starter (and leisure) 12v battery power goes first to the NE185 (or similar) and that unit then sends and receives information to and from the NE268 for that control panel to give its readings of voltage etc .also for the control panel to operate its functions via the EC185. Therefor, if the starter battery power is not getting to the NE185 in the first place it cannot send this information to the EC268. A faulty EC185 will also effect the EC268 control readings/operation. These units, NE185 and NE268 , must both be ok for the system and display information to operate as it should, which is why the repair people insist on both items to be sent to them when the testing of either unit is required.

I did take the van on the 60 mile round trip on Friday and when stopping after at the halfway point noticed that the battery was sluggish still when starting up for my return so when on my approach back home I took the van in to our local autos spark who tested it and confirmed the battery was knackered so fitted me a new fully charged battery. Went back home I had a look at the control panel and still getting the B1 reading of 0 V and zero percentage of charge left in the B1 battery,

Later that night I noticed I’d had a response email from a guy at Nordelettronica Italy asking me to check the starter battery supply at the NE 185 fuse board controller and then the 50amp fuse at the battery and sure enough the 50a fuse at the starter battery terminal was blown

So Iv since swapped it over and bingo success

Hopefully there wasn’t a fault anyway else the only thing I can think of is if I’ve sorted it with a spanner when I’ve been in the battery compartment, but we’ll have to wait and see but so far so good thanks for all your responses and hopefully that’s the end of it

Interesting as i have the exact same issue but cant see any noticeable marks on my battery fuse. We bought the MH and the vehicle battery was dead and put a new one in to find 0v reading, all the hab 12v stuff works when off hookup.
 
Does the leisure battery charge from the alternator when the engine is running? Does the fridge work from 12V when the engine is running? Some setups use the fridge supply wire as a voltage sense wire when the engine isn't running. If the fridge fuse has blown, you'll get no starter battery voltage reading, as well as, obviously, the fridge not working on 12V when the engine running.
 
Thanks i will test that tomorrow, i do recall it coming on but flashing but ive been back and forth at it today.

Ok managed to get out for 5mins and what i have found is:
Unplugging the electrics the Fridge seems to stay on however it does flash green on the strength.
Turning on the engine to van does not show any indicators on the LED panel thats its running, however i put the pump on and started lowering the electric bed etc to drain the battery and it got down to 12.7 and slowly started to creep back up to 13.5v so can only assume the van running is charging the battery.
I did not that the 12v socket ie for the TV would not work when the engine was running but does when connected to mains?
 
Looking at what the fridge says when everything is blinking it says to contact the dealer so not a good sign.
 
StevenGourlay Have you removed the battery 50amp power supply fuse, and checked it , as it may be defective underneath ? and if blown there will not be any input to the habitation fuse box (J1 terminal) and therefor none to the fridge main 12v power outputs. (the leisure battery may be powering the fridge controls) If it is ok, is there any power getting to the fuse box J1 terminal ?
