Avan poptop ceiling lights not working

Mike, Assuming that you have checked the bulbs, the most likely point of a break in the wiring is where it is stressed as the top is raised and lowered. The point where it bends to accommodate the movement of the top. It is possible that the copper conductors within the plastic outer covering are broken but with no visible evidence on the outside of the cable.

A simple troubleshooting method is to switch the lights on and be sure that there is a power supply. Then move the cable whilst watching the lights for any flicker. When moving the cable try not to pull on it but rather grasp it with two hands either side of the likely break point and press the cable in order to bring the broken ends together. Try doing this with the top not fully raised so as to not stretch the wiring tight.

If this does not produce a result then it gets a bit more complex and difficult to describe the necessary trouble shooting technique here. You may need experienced help.

Mike, most older poptops have a switch somewhere that you can move to 240 or 12 volt, if you are on 240 and the switch is set on 12v the lights wont work

hi mikeJ5
simple tests like these will eliminate before you start pulling the caravan apart
remove the globe and test it -- sit the bottom contact of the globe on the positive post of your 12v battery hold a bared end of some 12v cable onto the out side of the metal casing with your finger and put the other end onto the negative post of the battery this will light the globe if it doesnt its dead
sometimes its hard to see the break in a filament and this will prove one way or other
also if you happen to have a multi meter you can check the continuity of the globe filament and
also check for power in the globe socket with the switch on of coursethis will prove whether the power is getting
cheers

Thanks everyone for your replies. After some very helpful discussions with Avan customer service the trouble has been sorted. A small screw in the ceiling had apparanty worn through some insulation in one of the wires. Removed the screw and everything is working.
Thanks Ian from Avan.
