We have bought a 1991 Coromal Lowline Poptop which has had the fridge replaced. The cabin and outside lights do not work on 12 volt but the fridge does. Where can I get a 12 volt wiring diagram to trace where the light wires come from. This was the only low poptop that would fit under our garage roof.
Like most older caravans you'd have to be lucky to find a wiring diagram of any description. Being a Pop Top it shouldn't be too hard to trace the 12v lights wiring, there should be a flexible cable visable that goes up with the roof once you locate that it sould be easy enough to check with a multimeter & some test leads to check the light fittings to see if they are still connected.
Regards Steve.

Are the interior lights 12V or 240V? My recollection of vans of that era had 240 V lights, but I could be wrong (yet again) on that. Assuming that you have no on-board battery, the fridge 12V will come directly from the car plug and it will work whatever. If the lights are 12V, you will have a 240 V AC to 12V DC converter on board somewhere. This may be stuffed or you may simply have blown a fuse. Check under the seats for a power box. If the lights work when powered form the car, your problem is the converter itself (and you haven't blown a fuse). Good luck finding it....
We have a little 18ft full height Coromal 1998ish.
All 12v lighting.
I disconnected all the lights. and just ran some LED 2 mtr strips around the kitchen /Table area.
Draw curtains to bed area for privacy, and 2 LED strips one each side to individual bed light switche's.
TV/DVD is 12v.
Outside round light.
again removed globe. added a 5 mtr LED white strip along under inside edge of rollout.
using original sw to turn on/off. 50 times the light and brilliant white you can read by
I HATE yellow/off white light.
Simple cheap. MUCH better lighting. and uses 1/2 of one 20w globe a day if left on.
Those LED's leave all other lighting in a van for dead.and ute too.
Only 240v is Oven fan. microwave. fridge and Aircond. plus battery charger in fr boot.
HWS is Supply/demand. with internal striker battery. Gas heater, and 12v pump for flow.
Nice and simple with great lighting to read by. All over the van. inside and out.
That bloke who developed LED lighting deserves a medal times two.
I think most of these early vans have a simple ring loom
One line with take offs at each sw.
That's what we did with most Yachts we re-wired. with fuse at battery.
