12v socket in habitation area only live with ign off

[sueandjohn]

I want to run 12v device in 12v socket in habitation area. But it’s only live with ignition turned off.
Does anyone know how to make it live with ignition on

(I appreciate the problem of running down the leisure battery )

Thanks in advance

Make and model? Guessing it is a UK manufacturer....

 

[sueandjohn]

It’s a swift escape 664

Swift use Sargent control systems for the habitation power and the UK specification is that habitation power cannot be energised while the engine is running.

I expect the Sargent controller is sensing the Ignition live and switching on the habitation power only when the ignition key is in the off position.

You need to run an new socket from the vehicle circuit

Why not fit a new socket and power direct from the leisure battery.

Assuming you want to use a cigar lighter type plug, why not take a fused lead direct from leisure batteries and fit one of these where you want it....



If it is a USB lead you want to use, fit one of these....




Beaten again Doh!!

Another vote for running a seperate feed and socket.
Easier than messing about with the vans system.
It's a UK spec / build thing where the hab electrics go off while moving. No idea why..

 

[pappajohn]

No idea why..

National caravan Council recommendation I believe.
No standing in law like anything else they say.

Don't forget one of these

Can anyone come up with a LOGICAL reason for that?. We can use the inverter to run the Slow cooker, whilst travelling. Result?. HOT meal on arrival

Is it NCC or just a Sargent thing? My IH is British and has the NCC Approved Tick on the side. The 12v is active with the engine/ignition on.

Well,you learn something new every day...........like some vans don’t have hab electricity whilst engine is running.
So........how does the hab battery ever get charged,other than through ehu??
Or,am I being thick....again?

The leisure batteries are charged by the alternator when the engine is running.

Ah. Yes,I was being thick. Thank you for not pointing that out!!

I believe it's the cheap way out to avoiding EMC testing of the whole hab side for certification purposes with respect to, say, YourGadget in the hab area trigging an airbag or ABS brakes, sort of thing. Pure nonsense, every other country manages it OK.

Pull out the relay and fit a nice thick wire link. Or maybe it's not so simple with the Sargent controller.

Easy solution buy a German van - job done.

It's what I did. Trivial if you know a bit about wires.

If the leisure battery is under a seat it easy to mount a few sockets through the seat base direct to the leisure battery.

..or in an accident, knocked out by slow cooker flying forward and then burned by contents.

The clue is in the word "caravan". Nobody is in a caravan when it is being towed so no electrics needed. Then the rule was mindlessly applied to these new fangled motorhomes. Most British motorhome manufacturers came very late to the motorhome party.

Believe me ... It aint that easy !!!!!!

Doubtful in the extreme, Because the S-C sits in the kitchen sink and is behind the cross panel which has the massive seatbelt frame in front of it. We did it a lot in the USA and it works well.
