I have a 2005 Fleetwood Heritage 650ES twin axle caravan, I am in Australia.
No 12 volt power on fridge and the light between the radio and clothes cupboard also in the ceiling light between the toilet and shower.
Have checked all the 12 Volt fuses they are OK.
It was said the 12 volt power only works with the tow vehicle and 12 volt power attached, did that but allas still no 12 volt power.
There is no electrical diagram for the vans wiring so it is a nightmare trying to find the fault, may be it is a loose connection somewhere, but where?
Has any one experienced this? how was is diagnosed how was it fixed , what am I looking for to fix it?
Is there a decent 12 volt caravan wiring diagram for this somewhere, can I talk to some one that had the same problem.
