I figure all the wiring in my van must go back to a distribution point, right? I mean, looking at the leisure battery there are only so many wires coming from it. How do I find out where this is? I have one ceiling light which does not work, and it seems to be a problem of no power arriving on the van wires. How do I find out where that wire goes back to to make sure it is properly connected? The other two lights work so I am guessing they are all individually wired, and not on a loop.

I have an Autotrail Apache 1990 on a Mercedes 208 D Chassis.

use a tracer, the same way you track network cables. plug the transmitter onto the dead wire then trace it using the probe to where the signal stops

pick a cheap basic one up on ebay for about £13

I had one of those once when I used to install and maintain telephone systems. Good idea.

Would they not all go through the fuse box? ::bigsmile:

This is what I am asking you silly! :Doh: Where would the fuse box be? I can't find anything which looks fuse boxy, other than the 240 volt one. Where would I look?

usually near the battery charger......

Inside cupboards
In the wardrobe
Under the wardrobe floor.

Dont expect anything big....maybe no bigger than a fag packet with 4 or 5 blade fuses in.

I doubt very much your lights will be separately wired or fused....more like a broken wire somewhere

I may be miles off the mark here, but on some older AutoTrails some of the interior lights only work off mains electric. In other words, when you are on hook up.
A relative has an older AutoTrail and there are two lights positioned just behind and above the driver/passenger seats where the cab joins the hab area. These will only work on mains.

My fuses are behind my seat and ecu (where all the wires come from) is under the drivers seat so don't rule anywhere out as John said.

My old Merc Chieftain's fuses were all behind the dash on the passenger side - and what a shambles that was! The fuses were all ceramic with bits of brass strip of varying width. The only identification was in the Merc handbook which only covered the base vehicle. I spent many an hour with a multimeter chasing odd faults, sometimes having to rewire some of the circuits. :Doh:

You know this is going to be the very next test I do! lol Although I am not certain that this is the issue - the wiring to the light fitting looks distinctly of the 12v variety. Not that I am an expert at all! lol

I'll let you know
