Faulty transformer?

Recommended Posts

Hi I’m new to the site

 

we have recently bought a 2008 sterling europa 495 and this is our second time using it with the same resulting issues.  It’s our second caravan and have been caravaning for 3 years. 

The same issue has happened- after 2/3 days of use the lights go dim, the cooker  ignition stops, water pump stops, fridge light goes out & central heating fans stop( but heater still works) 

the display unit on  the mains isolater goes blank but the 3 switches- heater/water heater/ battery charger still light up.  Although this morning it now reads 7.8 instead of the 12? 

We always have the battery charger switched on. 

 

Its as though half the caravan is running in electric hook up and the other half is relying on the battery which is being drained very quickly? 

we leave home with a fully charged brand new battery- Duracell/banner 115ah

On our first trip this happened I suspected the battery so bought the new duracell battery for £130 but 3 days into our stay the same issues happened. 

 

When in use the caravan is hooked up to electrics. 

 

 

Ive checked the black fuse box and all fuses are ok. 

Next to the fuse box are 2 loose/free  wires with nowhere to go? 

 

Id really appreciate any advice on this as it’s driving us nuts!!

Take it to a dealer.  The seller should sort this out for you.  It sounds as if the charger in the caravan is not working.  When you leave home, how have you fully charged the battery?  Did you take it out and charge it with a bench charger?

 

On EHU al the mains voltage equipment will still work.  but the 12 Volt stuff will be running from the battery until it goes flat.  This will definitely shorten the life of the battery drastically.

I have a maypole smart charger that we use. Although this time the new battery arrived the night before we left so I just put it straight in the caravan as I assumed it would be fully charged- which is stated on the order letter it came with. 

The battery is a ncc class b battery so I assumed it would be ok? 

 

Forgot to mention that the motor mover gets used when setting up.

 

Ive read somewhere that the transformers on these caravans can be troublesome?

If you use the caravan before getting this fixed just take the Maypole with you and connect it to a mains socket in the 'van.

 

What Amp rating is the charger or what is  its model number?

Maypole mp7428 8amp.

its at home- I assumed a brand new battery would last a weekend away.

 

the charger was recommended on a caravan advice site

 

At least I’ve gotten a good couple of months to get it fixed over winter

It seems that the charger is not working. When plugged in the voltage should be around 13.4 rather than 12.

As a short term measure any charger will do but a proper replacement would be better.

If you bought from a dealer take it back for them to fix.

It would be cheaper to buy a new charger now than have to replace the battery again.  A 15A one would do.  Go to Halfords or an auto factor or a big supermarket tomorrow.  ;)

 

I see you are only away for the weekend.

Hi

Chances are that the charger is Nordelettronica Electrical long hisytory of problems with this manufacturer

 

sargent electrical https://sargentltd.co.uk › shop    do a direct replacment muti stage charge with a conveter cable

 

www.apuljackengineering.co.uk     do repairs / upgrade

 

other off the shelf chargers can be installed Get a muti stage charger

I would check if the power supply to the charger/power supply does not have kettle plug and been knocked out leaving it not connected .

 

You have got 240 v in the caravan ? Check the three pin sockets and any 240v lighting .

yes its a nordelettronica  model NE143_RM

 

Is it the whole unit that needs replaced ? If it’s just the charger where is it/what does it look like?

 

hopefully a diy job?

We had the same charger in our 2009 Sterling Europa and it failed after 6 years. Apuljack repaired and modified it  for us. We were going to replace it with a superior multistage intelligent charger but Apuljack advised this is already a multistage charger, and with a couple of tiny improvements is as good as any. I recommend this company.

Hi

If you Have 2pairs of wires  with no unit they are prob for the charger unit which may have been removed as a faulty unit the chargers where a free standng unit fixed to the floor or wall

 

1 ) will be the 230volt AC feed

2) the 12 volt ( 13.7 volt max dc )  supply from the charger to the van battery

If its a mulistage it can give out 14.4volts approx.

They are both thin wires next to the black fuse box- under the left front seat- the main A.C. feed is under the from right seat

 

Trying to google what the battery charger looks.......

 

 

daft question but is the charger separate to the mains isolater- ne143_rm?

You have the Nordelettronica system and that is very well known to a rubbish system.

However, help is at hand by way of Paul at Apuljack engineering.

He specialises in repairing these units and is the very best .

Give him a rig and he will Talk you through certain checks and then suggest a resolution.

 

I have used his services on numerous occasions on behalf of customers and his service is quite reasonably priced and quick

My battery is a Duracell 115ah- which apparently is a banner battery.

My charger is a maypole mp7428 8A smart charger

 

when connected to charge the charger stated 5% charged

its now at 95% charged  @14.6v / 0.8A

do these figures seem ok? 

I know discharging below 50% isn’t good but I’m hoping with it being a brand new battery it will recover?

You should wait until the voltage drops down to from 14.4 to 13.6 or thereabouts which indicates that the battery has now gone through it's charge and absorbtion phase and has dropped down to the maintaince/trickle charge phase. bear in mind that it will take at least 24 hours to recharge a flat battery.

 

Ignore the " % charged" display as it's only really a guess based on the battery voltage
