i have a bailey ranger 2008 460/4.when i connect caravan to my car electrics (Grey plug) it keeps blowing the battery fuse and car fuse in my caravan fuse box.Disconect the plug and replace fuses the fuses are fine until i conect back to car then they blow again.i have checked wiring in grey plug and the wires are ok. Any ideas what the problem can be please?

Hi Ian, you dont say if either car or caravan are new acquisitions? Has the towbar just been put on, or is this a problem that has occurred after previously being ok.

Hi Chris
It is a problem that has occurred since i have had caravan serviced,they put a new grey plug on caravan electrics (checked wiring and it is ok)dealer said i must have a dud battery on caravan.

I agree with Damian here sounds definately like a dead short or battery polarity reversed. First thing to check is battery polarity which is easy enough to do. I would then double check the plug wiring if it has only happened since a new one was fitted. Do you have a multimeter? If so check that the earth is sound, and then check to each other cable looking for very low resistance.
Do you have another car you can connect to? At least this would prove for sure that the fault is the van and not the car....

Stop and think for a minute peeps. When the OP plugs the cable into the car the fuses in the caravan blow, so (a) it clearly cannot be a reversed wire in the plug and (b) it must be something after the fuses that is blowing it.
Agreed a reversed battery connection could cause it, but so could any electrical appliance that is 'on line' and has reverse polarity protection.
One question to ask: does it blow when plugged into the car if the 12V on the caravan is switched off? If it does not then it must be an appliance, if it does then it can only be the battery.
