I have read with interest the recent forums on 12s socket, recently after picking my caravan 04 Bailey up from service I turned on battery power to find no power (I was plugged into car at time) so I can only assume that my car 03 Octavia has incorrectly wired socket, it was okay with my 92 Monza. So presumably the car is not charging caravan battery whilst travelling, is not working fridge and can't be used in emergency if leisure battery dies. Can anyone advise if this is common problem? I don't remember my towbar fitter asking me what age van I towed and how can I rectify it? Thanks in anticipation
