Clicking noise

Perhaps a bit more explanation Bullets - do you mean just a click on connection or is it continuing. I certainly have not encountered it on any of my outfits over the years.

Doesn't sound normal to me but it might be of further help if you advise is it from the car or the van and is it with the engine running or not?

Voltage sensitive relay in the car perhaps ..... you can usually tweak them

Hi all, yes sorry its only when the engine is running. noise is coming from the rear of the electic box in the caravan. it is a continuous click

I would suspect it is your car alternator rectifying circuit that is at fault and you are not feeding a clean 12v DC to your caravan. If you have had any problems with your car battery or lighting then this is almost certainly the case.

First I would check the connections between your caravan and car especially the earthing circuit.
