12v Lighting problem help please

[obree]

I have a 2005 Coachman Pastiche 540/4 , I have a problem with the caravan's 12v lighting . The lights in the toilet back bed area and one light in the lounge area are working fine but the remainder of the lounge area lights the outside light the kitchen lights and two ceiling lights are not working the fuses are ok . Can anyone help me please .

This maybe blatantly obvious,but have you checked the bulbs are ok.

Sounds like a broken wire somewhere . Best to check . There will be a junction connecting block where the power splits to the different parts of the caravan. Quite possible one circuit has become detached. Finding the wires is not easy. Sorry 🙂

Sometimes lighting circuits are split into front/rear or other sets. If your check of the fuses was just visual, change them anyway - occasionally they look ok but are still faulty.
As DD says, this is not easy. Perhaps another Pastiche owner knows how accessible the wiring is. This could be either a power or earth wire fault too.
You have one light working in the lounge,so expose the wires to this, and one of the non-working lights. Connect a cable between the two earth connections - if the dead light now works, at least you have narrowed to problem to the earth side. If it doesn't, repeat with power wires. Either way this should pin down which wire to chase down.
