Bailey Bathroom Lights sometimes not working?

[GlennB]

I've got an intermittent fault with the bathroom lights on my Series 7 Pageant Bretagne. A bad connection somewhere means they sometimes wont work. I don’t think it’s the switch, I think there is a fault with the wiring.
My question is does anyone know the route the wiring takes between the distribution box on the n/s & the bathroom on the o/s - and also where are the joints / connections?
The van is still under warranty so I could take it back but it's a hassle so I would rather have a quick look myself first.

If the van is under warranty and you "have a look yourself" you will invalidate the warranty for that fault.
The cost of repair will then be YOUR responsibility.
Put up with the hassle and get the supplying dealer to fix it AND maintain the warranty.

BTW it is VERY easy to identify if someone has been fiddling.

I think you are way off the mark about invalidating the warranty because I had a look myself.
The warranty will only be invalidated if I cause damage or further faults by looking - which I dont intend to do.
In this case I assume that the bad connection will be at a junction most likely behind one of the ceiling domes in which case the work needed to check will be no more invasive than it would be to change a bulb!!
I fitted my own BBQ point last year & rang the dealer to check if that would invalidate the warranty - the answer was no it would not so long as I dont try & claim in the future for water ingress caused directly by the fitting of the BBQ point.

Fixed it.
For the benefit of others the problem was corrosion on the wiring that goes into the pull cord switch. The switch brass contacts had also corroded where the wires attach. The fix was to run a drill bit down the bores of the switch & to trim about an inch off the end of the wires unitil the cores were good again. Took all of ten minutes.

Surprised at the amount of corrosion on there the van is a June 2009 & the shower has only been used maybe half a dozen times because we always use site facilities. We do use the bathroom as a drying room for towels etc so maybe that has caused it. Anyway i've put some wd40 around the contacts so it shouldn't re-occur.
