12v problems on swift corniche 17/3 year 2000

[ianwilliams1008]

HELP
we have recently bought the above caravan, now none of the 12v lights or radio will work, the battery is brand new ( have an older Leisure battery and tried that too) motor mover is working, battery meter says full power, but no lights or anything else, the 240 mains system is working fine, and battery charger light seems to be working all ok.
have read about an inline fuse, but cant find any where.. Has anyone got any ideas?

Hi Ian.Two thing here spring to mind. One are you attached to the motor vehicle while you are trying the lights atc in the van .The second one is if you look carefully behind the battery you may well find there is anline fuse behind the batter or even just onside van where the power comes in. I ask if you are connected to the tow vehicle because if you are the habitation relay comes in and shuts the 12 volt side off.
I hope this helps.
Sir Roger

no we aren't connected to the 4x4. the van is parked at the top of our drive, I have tried several times to find the inline fuser but cannot see any, found a fuse box under front seat / bed marked battery lights (above the car lights fuses for indicators etc..) changed that no difference..
am really stumped

 

[SirRogerFFS]

Ian check the batter box if there is no fuse in there then follow the loom into the van.as it comes into the van there could be a fuse in there.It may not be an in line fuse but a spade fuse (Ford Type).It shouldnt be far away from that location.Ian I have just searched your van and its saying the fuse is behind the battery in the battery box.

We have a Corniche, but much older than yours. Are you sure there is no fuse in the battery box. There is a 60A fuse in ours.
Also, have you checked the changeover switch from car to caravan.
If nothing works on 12v then it seems unlikely to be one of the 12v circuit fuses.

 

[ianwilliams1008]

yes checked switch, and honestly no fuse in battery box

 

[Damian]

There will not be a fuse in the battery box (except maybe for early fitted movers, but that is for the mover only).
There should be a 20Amp fuse in the positive cable just after entering the van, probably tucked under the battery box itself.

 

[ianwilliams1008]

hey we found the 20 amp inline fuse under battery box ( great design idea) it was fine so back to the drawing board am afraid. Still have no idea what the issue is

 

[SirRogerFFS]

Could be the habitation relay. You now need somebody like Damian to to advise .

 

[ianwilliams1008]

thanks .. Who's Damien?

 

[WoodlandsCamper]

thanks .. Who's Damien?

The person who answered you higher up in the thread. :lol:

 

[ianwilliams1008]

Damien, I have been told you are the guy to ask, please read the full thread, it was not the in line fuse...

 

[SirRogerFFS]

Ian ...Damian is a Moderator on this board and hes also a service engineer this is more up his street than ours.He did reply earlier to this thread. I can only advise on basics and problems I have had but Im sure Damian will have come across this problem before and Im sure he will pop back in again .

Ian just had a thought. Does the toilet flush work.I know when our power is switched off the toilet will still flush.Im thinking maybe power is still not getting through.Is there anyway you can check power is getting past your fuse you have found
Sir Roger

 

[ianwilliams1008]

Hi Sir Roger, will check toilet, but one thing to remember the meter is showing full battery, this is located in main switchboard on entry to the caravan.. will reply about the toilet in a mo

 

[ianwilliams1008]

just checked no power to toilet flush either

 

[SirRogerFFS]

Ian Have you got a multimeter.Or anyway you can actually check what is in you battery as the onboards are not that accurate.I would have thought the toilet would flush as our van is from the swift stable and flushes when power is turned off Again Ian Im clutching at straws now. If you can put a meter across your battery and get a reading that way.

 

[ianwilliams1008]

Thanks, but sadly I don't am afraid it will have to be a call out to a local servicing guy see if he can sort..
but appreciate all the feedback

 

[Damian]

Sorry for taking so long to get back.
I assume that for the purposes of testing your system that the main power from the mains supply is disconnected?

If it is not, then the battery meter in the van will be showing what the charger is supplying.
Can you advise what power distribution system you have, is it Nordelettronica?

If it is, that is where the fault will be.

 

[ianwilliams1008]

all Sorted now thanks To Richard Young of Mercia Mobiles
it was a fuse n the 230 electric box, we would never have found it

 

[SirRogerFFS]

Well done Ian and thanks for letting us know.Each problem solved is a help to the forum.
