No 12v lights or flush working following move

what about any other 12 volt appliance? Could be as simple as a fuse that's popped ..... they do age, and 170 miles of being bumped along might have been too much for it. 

Sometimes you need to have the light switch turned on in order for the wc to work.  Otherwise agree with MM.

If it's a multiplicity of 12v appliances, it's almost certainly a fuse.

12v may need to be re-selected to be on after towing.

On panel above door maybe?

Thanks everyone. Any idea where the fuses are likely to be ? The lights did flicker before going off though a couple of times, which seems odd. Someone suggested a bad to connection to teh battery maybe, but not sure where taht is either. The trips are all loocated in a box under a seat, where there also seems to eb some kind of additional charger. I have one wherring away next to where the mains supply is plugged in and this other one next to the trip board.

Thanks

Could you have dislodged the connection to the battery by moving it?  Fuses are often inaccessible under the beds!  My current one has been at the front under the bed - and have also had them under the bed nearest the kitchen. 

It does sound more and more like a fuse.  Have you not got a panel somewhere containing a load of spade type fuses (same type as in a car) which protect the various circuits, in my Bailey they are by a front bed.   Also near the battery there will  be a fuse on the red cable which may be faulty - mine is tucked under the battery box accessible from under the bed.  Get them all out check them and clean them.

Doesn't the handbook help? A multimeter is a useful bit of kit to have for the amateur to check for electrical faults.  If in doubt get the system checked out properly by an electrician who shoulld solve the problem in a couple of minutes!

I take it you do not have a handbook?  Do you know the model year?

The number engraved on the windows can give you that if you do not know.

Then you can get handbooks from the Swift website.

Maybe some help here......

Excellent, thanks all. I will get a copy of the owners manual and check out the fuses.
