Hello guys!
Recently, i went on the sea side for a week or so, and i was off grid all the time, with external temp below 0.Last day, the control panel text me "5er". It s a Nordelettrica 268 with NE 185 central.
Even if i run all day with motorhome, the control panel didnt restarted, the only way was to charge it from the hook.
After another 2 weeks of freezing cold, the panel îs dead again, but hab battery sems to be ok... 13.7V. Maybe the battery was drained and the solar panel recharget, but not enought. I cheched the fuses bord, connectors, cab and hab batteries, fridge is working on 12 v with engine running... What i knowdest is that on running engine, cab battery is charge from 12.8 to app 15 V, and the hab battery sems not to be charged... maybe if its full on 13.7V, the alternator will not overcharged?
It is possible that, somehow, the control panel remains blocked after a very low hab battery level? Is there a relee who might not work anymore and the hab electric circuit remains closed?
Thank you în advance for any kind of advices!

There is a big fuse in the wire very near the hab battery, maybe 30A or 50A. Is that fuse OK?

The split charge relay is located on the NE185 Distribution Board. It is the square black box between the large B1 and B2 terminals. Check the voltage at the B1 and B2 terminals. They should be exactly the voltage of the hab and cab batteries when the engine is not running.

I guess the D+ signal which switches the relay is working, because you say the fridge works when the engine is running. It wouldn't work without the D+ signal.

When the engine is running, the B1 and B2 terminals should be at the same voltage as each other. If they are different, the relay is not working.

Delta Conversions will repair it or sell you a new one.

Also Apuljack Engineering repair this type of board

Hello Autorouter, and thank you for your time:) The big fuse is ok, and i have voltage on B1 and B2... i didnt compare it with cab and leisure batteries, but i will. It is possible that the relay remain blocked and only a full charge battery to release it?? For now, i ll let the motorhome charging for 48h and if IT s still not working i ll charge the hab battery with a smart charger... anyway, if its not the battery Issue ill contact guys from Delta... still hopping to find a loose connection:)

If the relay is supplied about 12V to the coil, it will click, and connect the two power contacts (B1 and B2). You will see the voltages change, from whatever the battery voltages are, to some voltage in between those two, but both the same. If the alternator is charging, the common voltage will rise to maybe 14V or more as the two batteries are being charged.

The low-power supply to the coil, about 12 or 13V, will be one of the connections near the relay, but I'm not sure which one. If you find out which one it is, you could remove the connector and try a 12V wire direct to it. The relay should click on and off as the 12V-powered wire is connected and disconnected.

Unfortunately I don't know enough about the Nordelettronica NE268 control panel to tell you if there is some kind of cutout that needs resetting. I wouldn't be surprised if you are right about that.

Is that an ON / OFF switch bottom left? Does it operate a relay for power ON?

One extra note. Your leisure battery won't be at 13.7v. That is the level of charge going into it. Worth turning off hook and solar and wait an hour and measure battery voltage to see if it is healthy (12.7 or 12.8v fully charged).

Stealaway, if your r asking about The switch in picture below, i have no idea how it works... i just knowdest that în vertical position îs getting out of his place and i have no power in control panel

Jev88 ok...i ll do tomorow the right measurement

I'll also check the relay...

Thank you all:)

The switch in the bottom left with the C- is usually the symbol for ON- OFF
Click to expand...
In the posted picture the symbol is sideways. To explain, the symbol is a combination of 0 and 1.
0 = OFF, 1 = ON. (in German it's the same word for ON and 1: 'ein'). So it's an on/off switch. Maybe the main 12V power switch.

Hello again...
I'm back with same problem... today i just visited a motorhome repair center în Bucharest, and they try to find out the Issue.. after 2 hours they say that 90% is a fuze box Issue and 10% unknown...
It is posibile that the fuze box to be faulty and in the same time frigde is working în auto mode when i start the engine?

This switch is a heavy-duty isolator switch, usually used as a battery isolator. When the red plastic 'key' is removed, the switch is OFF.

The fridge relay and the split charge relay are separate items, triggered by the same D+ signal from the alternator. If the fridge is switching on when the engine starts, that means the D+ signal is working OK.

Check the voltages at B1 and B2, with the engine not running, then with the engine running. That will tell you if the split charge relay is working or not, as I described in post #2.

Thank you... so tomorow i have work to do... :)

So.. i've checked the relay, with working engine and it seems the tension îs different on B1 and B2, but when i put low voltaje directly, i can hear the click în the relay and bouth bateries is charging... so, the D+ sent the right signal for the fridge but no signal to main relay.
I send an email to Apuljack and one to Delta Conversion, asking them if they have a new fuze board or if they can repair the faulty one... now i Wonder if they will send it în Romania:)

Thank you all for help and your advices!
Best regards!

Try a search for Leisure Electronic Repairs they will be able to sort out the panel 7 day turnaroun.

Perhaps it is just the angle of the photo, I can’t see the fuse link.

How did you get on? did they answer?

Found this article in MMM, it tells you to disconnect the power for a couple of minutes, they mention delta conversions, you may have to change to a different control panel.

AndreiS did you change/check the RJ45 cable, it seems to be a common cause of a blank control panel?

Has been disconnected via Batteries not connected for days, don't think control panel, as there is only signals going to it, not much power to cause problem

Peregrinator The problems that can happen with the NE 268 control panel are (according to Apluljack electronics) , Wont switch on / off , No power to panel , Battery voltages incorrectly displayed , Pushing one button activates a different function. If any of these faults is the problem that you have it may be worth talking to them.

NE 274 Control Panel Don't switch on, most likely problem being NE 185-15s, has to the companies people have mentioned, They don't answer their messages, Don't repair PCB's anymore or can't get the parts as can't order anymore because Nordelettronica only supplies to dealers & manufacturers.
